Middle class in India : Problems and Prospects

 Why is it in the news ?

1. Budget of FY 25-26 gave concessions to the middle class by alleviating the tax burden upon them. The finance minister raised the income tax exemption threshold from ₹7 lakh to ₹12 lakh per annum. The inclusion of ₹75000 as standard deduction alleviates the tax free income limit to ₹12.75 lakh. Thus, those taxpayers who are earning ₹25 lakh annually can save up to ₹1.1 lakh, individuals earning ₹10 lakh can save ₹50 thousand and individuals earning ₹15 lakh can save ₹75 thousand.

The new tax slabs would give the following benefit to the people

Income	Total Benefit
Up to 8 Lakh	₹30000
9 Lakh	₹40000
10 Lakh	₹50000
11 Lakh	₹65000
12 Lakh	₹80000
16 Lakh	₹50000
20 Lakh	₹90000
24 Lakh	₹110000

The tax concession caused a revenue loss of approximately ₹1 lakh crore to the government. However, the government expects that the tax reduction would boost household consumption and improve economic growth by creating aggregate demand in the economy.  The government was forced to give concessions to the middle class because according to RBI data, the net household savings as percentage of GDP was at the lowest level in the last 50 years. Secondly, the mounting unsecured loans have pushed net savings to a low level, leaving families with less disposable income. Elevated food inflation, high interest rates and shrinking discretionary income have made it difficult for the middle class to maintain their previous spending levels.

Who is middle class in India ? 

1. According to the People Research on India’s Consumer Economy (PRICE), the middle class consists of individuals having annual income between ₹5 lakh to 30 lakh. 

2. According to NCAER (Council for Applied Economic Research), the middle class in India are those whose annual earning is between ₹2 lakh to 10 lakh. 

3. According to the World Bank, individuals earning between $10 and $20 per day (₹313200-522000)are in the middle class. 

4. According to Pew Research Centre, individuals earning between $10 to $20 per day can be put under middle class. 

5.Apart from income criteria, the middle class can be defined also on the basis of occupation. It includes salaried professionals, government employees, small business owners and skilled workers.  

Changing contours of middle class in India

1. The middle class now represents 31% of India’s population of 1.40 billion. It is projected to hit 38% by 2031 and 60% by 2047. Thus, by the middle of this century India is projected to have a middle class population of around 1 billion. 

2. During the British Rule, a small number of middle class arose on account of industrialisation in India. They were professionals, business managers, lawyers, doctors, bankers, teachers etc. 

3. After independence, the middle class was largely created by the public sector undertaking. However, by 1995, the organised private sector became also powerful employing 80.6 lakh while the public sector employed 194.7 lakh. Before the year 2000, public sector undertakings and railways had a predominant share in employment but after 2011-12, the trend shifted towards IT companies. Now they employ more than railways, public sector undertakings and defence. Similarly, the private banks also surpassed in 2023-24 the scheduled commercial banks in matters of employment. Thus, IT, finance, accountancy, legal, health, hospitality, tourism, transportation, logistics, aviation, media, advertising, sports, entertainment, real estate and retail services led to the growth of the middle class in India. The middle class has now become all pervasive. It has now spread even to rural areas because of the rising incomes of farmers and individuals living in villages. The new middle class arose because of the exponential growth in the services sector.  They are employed more in IT, MNCs, and the Gig economy. They have multiple sources of income. They are highly entrepreneurial and want to launch a startup to get self employment instead depending upon government jobs.  However, since the Indian economy did not experience structural transformation like in China, the middle class rose more in the services sector. The limited growth of manufacturing and agriculture sectors put a limit on the growth of the middle class in the primary and secondary sectors. Even in the services sector, the growth of the middle class is limited because of insecurity of job and low paid salaries to workers employed in the unorganised sector which constitute 94% of the total employment in India. Similarly, India witnessed huge growth of Gig workers in companies like Zomato, Uber, Ola, Flipkart, Amazon. But because of their insecurity of job and low paid salaries, these sectors put a break upon the growth of the middle class in India. 

Problems of middle class

1. Although the middle class in India produces half of the national income, it is being confronted with several problems. These are : 

• Wages are not increasing in proportion to the rising inflation. 

• There is huge competition for getting government jobs. Thousands of candidates apply for the high salaried jobs for a few posts, showing acute unemployment among the middle class in India. 

• Because of the advent of artificial intelligence and automation, most of the managerial posts in the companies are disappearing. 

• Because of the digital platform, the Gig economy is rising. But Gig workers have low paid salaries and insecurity of tenures, putting a break upon the growth of the middle class. 

• High cost of education and healthcare further reduce the disposable income of the middle class. 

• Skyrocketing property prices makes it difficult for the middle class to own houses in the urban centres.

• Increasing expenses on account of rising cost of diesel and petrol have put a break upon their mobility.  

• Long hours of work in banking, IT and corporates have strained their physical and mental health. Work pressure leaves little time for their personal upkeep and prevents them from leading a good family life. 

Prospects of middle class 

1.The prospects of the middle class in India in the coming year are very bright.

2. It is expected that by 2050, the population of the middle class would go to one billion. Thus, it would have more political clout than before. 

3. With the increasing disposable income , the middle class would be investing more in mutual funds stocks and crypto currencies. 

4. Due to the government's efforts to launch a smart cities mission, the middle class will find affordable housing facilities. 

5. The increased income of the middle class would further lead to the growth of real estate, automobiles and consumer goods.   

6. With the increasing population of the middle class, there would be a shift from blue colour jobs to white colour jobs in the sectors like E-commerce, IT, Finance and Health sector. 

7. The digitalisation of the economy would further boost the expansion of the Gig economy, E-learning and skilling. These new avenues would further boost the growth of the middle class in the country.  

8. With the higher disposable income, the new middle class would venture  start-ups more vigorously.  

9. The National Manufacturing Mission initiated by the government would further broaden the base of the middle class in the sectors of manufacturing, construction and transportation. 

10. The expansion of the Green Revolution in Eastern India by the injection of new technologies would further raise the income level of farmers and individuals living in rural areas. This would further expand the base of the middle class in the agricultural sector.  Dhan Dhanya Krishi Yojana initiated in the budget 2025-26 would further boost the production and productivity in the 100 low productivity districts in India, increasing the income of individuals living in rural areas. This would further broaden the base of the middle class not only in the urban centres but in rural areas also.   

Conclusion 

1. The Indian middle class is an aspirational class. With the increasing income, digitalisation, urbanisation, transformation in agricultural and industrial sectors, the middle class is going to become the most powerful class and the engine of growth of the Indian economy. It is hoped that with the growth of the middle class, Indian democracy will further strengthen. 

2. The rising middle class would be able to surpass the US by 2050 in nominal GDP, becoming the second largest economy of the world after China. Thus, the future of India lies with the growth and aspirations of the middle class.

Why are Indian Rupees dipping vis-a-vis USD?

 Why is it in the news? 

1.The Indian rupee slumped to 49 paise to breach the 87 mark against the US dollar on the last Monday. This downward value of rupee was on account of the meltdown of currencies of the most emerging market currencies and stock markets across Asia and Europe when President Donald Trump imposed higher tariffs on Canada, Mexico and China. He also talked about reciprocal tariffs. This led to the adverse market sentiments all over the world. 

2.It should be noted that in November 2024, the value of rupee was 84.36 rupees vis-a-vis one USD. Within a short span of three months Indian rupees further slid to 87.12 rupees per USD. 

[Source: The Hindu] 

Causes of falling of Indian Rupees vis-a-vis USD

1. Dollar index has been high over the last couple of months. The dollar is appreciating. Dollar index is pretty high against all currencies not only of emerging markets but even with the developed countries. The dollar index has picked up again and is above 109. The dollar index is a measure of the value of the US dollar relative to a basket of 6 major foreign currencies. These major currencies are Euro, Japanese Yen, British Pound, Canadian dollar, Swedish Krona and Swiss Franc. When the dollar index rises, it means the USD is strengthening against these currencies. A strong dollar makes imports cheaper for the US market but can hurt emerging markets like India and imports become more expensive. Thus, a rising dollar index often leads to rupee depreciation. The strengthening of the US dollar has been due to high interest rates which attracts global investors. Rising US treasury yields attract investors to prefer US bonds over emerging market assets, leading to the capital outflow from India. 

2.Secondly, rising prices of crude oil has increased the demand for USD, thereby putting pressure on the Indian rupee. It should be noted that India is dependent on foreign countries for 88% of its energy needs. Since, trade in crude oil and LNG (Liquified Natural Gas) is done in USD, any increase in the prices of these commodities put pressure on Indian rupees and raise the demands for more USD. 

3.Thirdly, geo-political tensions like Ukraine-Russia War, Israel-Hamas War in the Middle East, protectionist policies adopted by developed countries and slow global trade reduced the confidence of investors in the emerging markets like India. 

4.Apart from global factors, there are domestic factors which cause weakening of rupees vis-a-vis the American dollar. These are -

• Trade deficit - India imports more than exports. This leads to an increase in demand for USD and weakening of rupees. Export in merchandise trade reached USD 284.31 billion and service trade reached USD 215.98 billion between April to October 2024. While imports of merchandise goods stood at USD 486.73 billion and import of services reached USD 114.57 billion between April to October 2024 [Source : PIB]. Thus, there is a trade deficit of USD 101.01 billion in the above period. 

• High inflation in India reduces purchasing power of rupees and thus, weakens confidence of the investors. 

• Slow down in FDI and remittances further decreases the supply of USD.

• Outflow of foreign portfolios further weakens rupees and increases demand for buying USD. In 2024, foreign portfolio investors withdrew approximately $9 billion from Indian equities.  

• Fiscal deficit and government borrowings - a high deficit often leads to higher borrowings which increase inflationary trend in the economy leading to the weakening of Rupees. That’s why the government has set the target of achieving a 4.4% fiscal deficit of the GDP in the current budget of 2025-26.

What should India do to arrest the slump of rupees ?

1. India needs to strengthen its exports by diversifying its trade agreements with emerging markets of the world. 

2. RBI should intervene whenever there is volatility in the market to arrest the fall of rupees vis-a-vis the US dollar. 

3. More emphasis should be given on foreign direct investment because it entails long term investment rather than on Foreign Portfolio Investment which is only for short term investment. 

4. Domestic institutional investments should be given more priority over FPI and FDI so that DIIs can offset the loss of money on account of outflows of FPI. 

5. There is a need to raise vocal for local so that indigenous production of goods and services gets priority over foreign goods and services. Moreover, India needs to become a manufacturing hub like China so that its dependency on imports is drastically reduced. More emphasis should be given on renewables so that rising import bills on crude oils and LNG are reduced. 

6. Fiscal deficit should be reduced so that inflationary trend in the economy is checked. This is why the current budget of 2025-26 aims at keeping the fiscal deficit at 4.4% of GDP. 

Conclusion 

India should seek alternative methods in international trading. Instead of depending upon USD, it should explore ways and means to trade in local currencies as it had done with Russia so that its dependency upon USD is further reduced. Moreover, India should strive for self-reliance in production of machinery, electronics, IT ,pharmaceuticals and renewables.

Uniform Civil Code

 

Why is it in the news?

1. Uttarakhand officially implemented the uniform civil code for all residents of the state on 27th January, 2025 except scheduled tribes and natives who have migrated out of the state. Thus, Uttarakhand has become the first Indian State to implement the UCC after independence as mandated by the constitution of India under article 44. Goa already had a common civil code in India. Several BJP ruled states like Haryana, Assam, Madhya Pradesh and Gujarat have constituted committees to enforce uniform civil code in near future. 

2. The Act bans practices like Halala, Iddat and Talaq. It ensures that women are given equal rights in matters related to property and inheritance. 

3. According to the provision of UCC in Uttrakhand, all those people who have got married since March,26,2010, will have to be registered in the government portal within the six months. Marriages that have taken place after the implementation of the law should be registered within 60 days from the date of marriage. Similarly, live-in-relationship established before and after the implementation of UCC will have to be registered within one month from the date of implementation of the UCC.  

4. If the woman becomes pregnant during the live-in, then it is mandatory to inform the government within 30 days of the birth of the child. The UCC also mandates that a landlord cannot deny a house to any couple whose live-in registration is done. Thus, It mandates online registration of marriages, divorces and live-in relationships. A government portal has been formed for this purpose. People can access records, register complaints and also upload their will on the portal.  The government claims that the UCC will bring equality and harmony. It also hopes that the stream of equality emanating from Uttarakhand will irrigate the entire country in the future.

What is Uniform Civil Code?

1. UCC refers to replacing personal laws based on religious scriptures and customs with a common set of rules governing every citizen. These laws cover marriage, adoption, inheritance, divorce and maintenance governed by respective religious scriptures. 

2.  Under article 44 of our constitution Uniform Civil Code has been put under the directive principle of state policy. The provision states that the state shall endeavour to secure a UCC for all citizens throughout the territory of India. 

3. It is suggested that UCC would lead to equality, gender justice , promote national integration, eliminate complexities of different personal laws and modernise civil laws as per the needs of the contemporary society. 

4. Detractors give the following arguments against UCC : - 

• It would infringe the religious freedom guaranteed by the constitution of India under article 25, whereby every citizen is entitled to propagate, profess and practise his own religion. 

• India has cultural diversity. Different communities have different customs and traditions. Even among tribals, the customs and traditions of North Eastern Tribes are quite different from that of tribals living in Central India. 

• Different religious communities have resisted the implementation of UCC in India, alleging that it would compromise their religious freedom. 

• Political parties except, BJP, dither to implement UCC lest they get alienated from minorities. 

Difference between Uniform Civil Code and Common Civil Code

1. UCC stands for uniform laws for all citizens irrespective of their religious affiliations. It is secular and universal. It is rigid and uniform for all communities.

Common Civil Code on the other hand does not necessarily mandate complete uniformity. 

2. It can allow for some degree of flexibility. It allows diversities while seeking harmony. Thus, it gives special consideration to customs and traditions. 

The present position of UCC in the different countries of the world.

Most of the western countries like the United States, Canada, France, Germany, Australia have UCC. Islamic countries like Turkey, Tunisia, Indonesia, Kazakhstan, Uzbekistan and other Central Asian Republics have adopted UCC. While other Muslim countries have still clung to Sharia laws.  

Historical Background 

The UCC was fairly discussed in the constituent assembly.  No unanimity among its members could be arrived at. Both Jawaharlal Nehru, Dr. Ambedkar, K M Munshi and women members were in favour of the binding implementation of UCC but the Muslim and Christian members vehemently protested against making UCC as enforceable by law.  Thus, a compromise was arrived at for want of consensus and it was put under Directive Principle of State Policy under article 44. 

Why has the uniform civil code not been implemented in India despite a constitutional mandate?

1. The fear of losing religious identity among minorities.

2. Political parties refrained from implementing UCC due to fear of backlash from minorities during the election.

3. Apprehension of social unrest by minorities.

4. Lack of consensus among majority and minority communities. 

5. Lack of awareness with regard to UCC.

6. Diversity and plurality of Indian society makes the UCC unfeasible. 

7. Encroachment upon the right to minorities under article 29 and 30 of our constitution.

The Way out 

UCC can be implemented by making consensus among all stakeholders. It requires gradual rather than drastic implementations. Moreover, citizens should be educated with regard to the benefits of the UCC. But the customs and traditions of tribal and other vulnerable communities must not be interfered with through the UCC.   

Why did Sultan Mohammad Tughlaq fail miserably as a ruler?

 

1. Sultan Mohammad Tughlaq was a widely read person. He was well- versed in History, Theology, Mathematics and Persian. No Sultan before and after him was so educated as he was. But he was impatient and acted in haste. He did not give enough time to his project to be implemented efficiently, with the result that most of his experiments/projects failed. These failures sapped the vitality of the Sultanate. The final nail in the coffin of the Sultanate was struck by Taimur Lang in 1398. Taimur looted and plundered Delhi, massacred its people and took away thousands of cattle, artisans, valuable goods with him to his capital,Samarkand.

2. The Sultan annexed the entire South India. But it could not be administered properly from Delhi for want of proper communication in those days. In 1327, he made Devgiri as his second capital to control South India. A road was built to connect Delhi with Devgiri, renamed Daulatabad. Trees were planted on either side of the road. Sarais or halting places were constructed every two miles (1 mile = 1.6 km).  Nobles, Sufi Saints and people from Delhi were exhorted to shift to Daulatabad. They were provided lands and residential places. But the experiment failed miserably. It came out that as South India could not be controlled from Delhi, so North India could not be controlled and administered from Daulatabad, a town situated 1500 km away from Delhi. Thus, the experiment was shelved in 1333, after a gap of six years. But, the experiment caused heavy casualties of people and loss of wealth. A large number of people died of exhaustion because the experiment was carried on in the summer season. Secondly, those nobles or landed gentry settled at Daulatabad got homesick. They did not like the surroundings of Daulatabad. Moreover, the locals resisted them. So, some of the nobles returned to Delhi while others perished enroute. Although the experiment failed miserably, it led to the commingling of Hindu and Islamic cultures.  Islam hitherto restricted to North India, penetrated into Deccan and South India. The exodus of muslim theologians, sufi saints, military officers, nobles and landed gentry to Deccan led to the establishment of Bahmani Kingdom in 1347. Secondly, the commingling of Persian and Hindavi gave rise to a new language called Urdu. While Hindavi provided sub structure (base), the Persian provided super structure (Persian Vocabulary) to Urdu. In later years, Urdu proliferated to North India. And it is now the lingua franca of Pakistan. While in the states of UP,Bihar, Jharkhand, West Bengal, Jammu & Kashmir, Delhi and Telangana, it is the additional official language. 

3. Introduction of token currency - The Sultan introduced token currency in the sultanate. Thus, the face value of a copper coin was put at par with a silver coin. In modern times, almost all countries have adopted token currency. But in those days it was very new for the people in the sultanate. It is suggested that the Sultan took this measure because there was paucity of silver metal. Earlier, the Chinese emperors and Kublai Khan had also experimented with token currency. But the token currency in India introduced by Mohammad Tughlaq failed miserably because the Sultanate did not take sufficient measures to check the counterfeiting of coins. The administration failed to stop the imitation of token currency. People started hoarding gold and silver and paying taxes in counterfeiting currency. This led to the decline of trade and commerce and the overall economy of the sultanate. The sultan was forced to withdraw token currency. He ordered the genuine token currency of copper to be exchanged by silver coins. This experiment further put a heavy burden upon the exchequer of the sultanate.

4. The sultan tried to curb the power and influence of Ulema who had controlled the religious and judiciary department. He ordered that the monopoly of Ulema must be dismantled and all those people who were meritorious should get access to the judiciary, religious and ecclesiastical department. This infuriated the Ulema, theologians and orthodox elements in the Sultanate and therefore, started lobbying against the Sultan. But when the sultanate witnessed a series of revolts in the second half of his reign, the sultan was forced to make compromises with the orthodox elements of the sultanate. He invited Giasuddin, a distant relative of Khalifa and bestowed upon him respect and huge gifts. Similarly, most of the Ulemas and their descendants were restored to their original positions in the judiciary, religious, educational and ecclesiastical department. 

5.Similarly, the Sultan expanded the base of nobility by recruiting not only foreign Muslims but also native Muslims. Hindus were also recruited in the nobility. Thus, instead of hereditary, the merit found utmost importance. The liberality of the Sultan was very much detested by the orthodox elements and foreign Muslims. The cohesiveness of the nobility was completely torn asunder. 

6.The Sultan embarked upon agrarian reforms in Doab. An agricultural department called Diwan-e-Kohi was established to help farmers with Taqavi loans, seeds and implements. But because of the sudden outbreak of famine in Doab, the agrarian reform failed miserably. Moreover, the land was not measured before fixing the land revenue as was done by Allauddin Khilji. The land revenue was fixed as high as half of the produce. The outcome was that most of the farmers abandoned farming and fled to the jungles. 

7. The Sultan recruited 3 lakh 70 thousand soldiers and paid them a salary of one year in advance. The purpose was to capture Khurasan in central Asia. But on account of the changing scenario in central Asia, the project was shelved. This caused a heavy economic burden on the exchequer. Similarly, the expedition to Qarajal, situated in the foothills of Himalayas, proved a disaster. Almost all 10,000 soldiers perished in the hilly terrain.

8. The Sultan failed to check on revolt one after another revolt in his vast sultanate. Thus, Bengal liberated itself from the sultanate. In South India, Harihar and Bukka established Vijay Nagar kingdom in 1336. In Deccan, Hasan Gangu, a foreign Muslim, established independent Bahamani Kingdom in 1347. In Rajputana, Hamir Dev declared independence and defeated the sultanate army at Sugoli in 1336. Thus, in the second half of his reign, the Sultan kept on quelling one revolt after another revolt and died at Thatta in 1351 while subduing the revolt in Sindh. 

9. To conclude, several historians like Elphinstone and  V A Smith accused Mohammad Tughlaq of insanity or a mixture of opposites but this is not true. Most of his experiments were ahead of his time. Moreover, they lacked the force of proper implementation. The Sultan was in haste and was hot headed. He left most of his experiments in the middle without going for a final conclusion. Moreover, he lacked a sense of proportion so much so that he could not discriminate between the serious and trivial crime and so awarded harsh punishment disproportionate to the gravity of the crime. The nobility, the Ulema, the regional warlords, the foreign Muslims were always in the lookout to undermine the position of Sultan. These were the reasons for the failure of Sultan Mohammad Tughlaq.  However, the credit goes to the Sultan that he valiantly fought against Mongols and defeated them. In spite of so many revolts, the sultanate was saved from crumbling. 

Achievements in Science and Technology in Ancient India

Why is it in the news?

1.The noted historian William Dalrymple wrote the “Golden Road : How Ancient India Transformed the World?”. The book was published earlier this year, which gives the complete idea as to how India was everything that happened in the ancient world right up to the early stages of the rise of Islam. 

2.According to him, India, not China, was at the heart of ancient commerce. It was the bristling maritime trade between India and the rest of the world which boosted international trade. That India was indeed a maritime power touching Egyptian ports to the West and Indonesia and the rest of SouthEast Asia to its East. The outcome of this association was the construction  of the largest Hindu Temple complex at Angkor Wat in Cambodia and Borobudur, the world’s largest Buddhist shrine in Indonesia. 

3. Through the ages scholars, kings, caliph, emperors across the world from China to Western and Central Asia admired India as the principal knowledge hub even after the advent of Islam. India’s rich mathematical and astronomical tradition continued to dazzle the world. The Chinese emperors gave shelter to Indian mathematicians, astronomers, and scholars in their courts. 

4.The Historian William Dalrymple, brought out how ancient India was as great and as dynamic civilisation as China was at a time when the west was hardly in reckoning. According to him, Indians made astonishing advances in science and technology in ancient India.

Achievements in Science and Technology in ancient India

1.Ancient Indians made three important contributions. These are the notation system, the decimal system and the use of zero. The notational system was adopted by the Arab who spread it to the western world. The decimal system was borrowed by the Chinese from Buddhist missionaries. Similarly, Indians invented Algebra which was acquired by Arabs and spread to the western Europe. Brahmagupta and Bhaskaracharya further contributed in the development of Algebra and trigonometry. 

2. Zero was discovered by Indians in about the 2nd century BC. It was considered a separate numeral. The Arabs learnt the use of zero and then spread it to Europe. 

3. Aryabhatt calculated the positions of the planets. He discovered the cause of the solar and lunar eclipses. He measured the circumference of the Earth. He said that the Earth rotates around the Sun rather than vice-versa. He wrote Aryabhatiya. 

4. In the book Brihat Samhita, Varahmihir said that the Moon rotated around the Earth and Earth rotated around the Sun. 

5. In the field of medicine, Sushruta and Charak were prominent surgeons and physicians respectively. While Sushruta in his book Sushruta Samhita gives detailed description about the method of operating cataract, stoned diseases and many implements to be used for surgery, the Charak Samhita discusses various types of diseases and prescribes medicines for their cure. 

6. The drainage system and town planning adopted by the Harappans clearly show that they had knowledge of measurement and geometry. Sulba Sutras provides early examples of geometry. It provides precise methods to construct altars. Aryabhatt formulated a method for calculating the area of a triangle which led to the origin of trigonometry. The ancient Indians developed temple building engineering. The marvellous Ellora temples and Kailashnath temple which have been carved out from the single rock is an example of extraordinary engineering feat. 

7. The Lokayat philosophy provided by the Charvak argued that what is not experienced by man through his sensory organ does not really exist. Thus, he repudiated the existence of god. Similarly, philosophy of Sankhya was propounded by Kapil Muni. According to him, the soul can get liberation only through real knowledge which can be acquired through perception, inference and hearing. 

8. Indians developed the art of dyeing, the lasting colour is found in the paintings of Ajanta. 

9.Indians developed great expertise in the art of making steel. The iron pillar at Mehrauli (Delhi) did not rust even after the lapse of 1600 years. 

10.Kanad Rishi devises the atomic theory. He speculated about the existence of small indestructible particles much like an atom. He further held that atoms of the same substance combined with each other in a specific and synchronous manner  produced dviyanuka (diatomic molecules) and tryanuka (Triatomic molecules). 

11. India was the first to smelt zinc by the distillation process. This led to the making of bronze alloy by the mixing of tin with zinc. 

Decline of Science and Technology in India 

The science and technology declined after the onset of Muslim rule in India. The Sultanate period and thereafter, the Mughal period saw the growth of orthodox elements in the society. The Muslim religious leaders like Ulema, Mullah and Maulavi increased religiosity in the society. Among Hindus, the Bhakti movement took its root. The religious leaders like Ramanuja, Madhavacharya, Vallabhacharya, Nanak, Kabir, Tulsidas, Surdas, Mirabai spread the Bhakti cult in India. Thus, the ecosystem of science and technology was relegated to the background. Religious orthodoxy took precedence over logic and scientific temper. Moreover, the progressive and learned Brahamanas were denied privileges like land grants during the Muslim rule and so their creativity was stifled. The status of education further deteriorated during the period. And thus, India lagged behind in science and technology in the mediaeval period.  It was only after the second half of the British rule that science and scientific studies were given importance. Thus, the scientists like J C Bose, C V Raman, Homi Jehangir Bhabha,  Srinivasa Ramanujan, Vikram Sarabhai, Satyendra Nath Bose and Subrahmanyan Chandrasekhar were produced in India who made marks in the field of science and technology.
