UPSC GK: Understanding Champaran Satyagraha


At a moment when the ideals and events of our national movement seem to be fading from public memory, it is gratifying indeed that there should be a celebrations in this country of the centenary of one of the most remarkable episodes of modern Indian history, the Champaran satyagraha of 1917 that opened a new phase in the national movement by joining it to the great struggle of the Indian peasantry for bread and land.

Ever since the Battle of Plassey in 1757, British rule had meant a constant exploitation of India, the main burden of which had fallen on its peasants, artisans and the labouring poor. It has been the great intellectual achievement of the early nationalists that they were able to show how the twin processes of drain of wealth and de-industrialisation had ruined India. One sees the exposure and analysis in its classic form, in Dadabhoy Naoroji’s Poverty and Un-British Rule in India and, in the form of a historical narrative, in R.C. Dutt’s two-volume Economic History of India under British Rule. Mahatma Gandhi himself summarised these findings in his Hind Swaraj, originally written in Gujarati.

The impoverishment of India, which the early nationalists so ably exposed, was largely accomplished through means in which Englishmen themselves hardly ever appeared as the exploiters: the land revenue was exacted through zamindars or native officials; English goods, destroying Indian crafts, were sold by Indian shopkeepers and hawkers. It was mainly in plantations and mines that the Englishman appeared directly as the oppressor. And among plantations, it was the indigo plantations where such oppression had the longest history. Indigo was a celebrated product of India, down the centuries, raised and processed locally by peasants. But in the 17th century, European-owned slave plantations in the West Indies also began to produce it, the extraction process they used being improved immensely by use of boilers. When the English conquered Bengal, European indigo planters appeared there soon enough. Obtaining zamindaris, they coerced peasants into raising indigo for the dye to be processed out of the plants in their ‘factories’. The coercion exercised by European planters on peasants to raise indigo and sell it cheaply to them – under methods portrayed in Bandhu Mitra’s famous Neel Darpan – led to peasant ‘disturbances’ in Naddia in Bengal in 1859 and 1860. But these were suppressed by the administration.

Changing forms of oppression in Champaran

Indigo plantations extended into Bihar, where too European planters used the zamindari system to force their peasant tenants to bow to their will. Where they could not buy zamindaris they obtained leases from local zamindars, and in the form of ‘thekadars’ exercised the same rights over peasants as they would have had as zamindars. In Champaran district of Bihar, most European planters obtained thekas or leases for whole villages from the large Bettiah zamindari. Here, as the demand for indigo grew with expanding textile imports, the planters imposed what came to be known as the tinkathia system, the peasants being forced to raise indigo on the best parts of their rented lands.

A crisis occurred when a synthetic dye was developed in Germany in the late 1880s. Since natural indigo dye could not compete with it, indigo exports from India declined in value from Rs 4.75 crore in 1894-95 to Rs 2.96 crore five years later. As indigo prices and the planters’ profits from indigo manufacture fell, the planters began correspondingly to increase the rent-burden on the peasants, invoking their rights as zamindars. The impositions took two major forms: As zamindars or thekadars the planters simply increased the rents paid by peasants, the increase in rent being called sharahbeshi, usually amounting to 50-60% of the previous rent. The second form was a curious one. Since indigo prices fell, the peasants did not now wish to produce indigo, as they had to under the tinkathia system. The planters, who did not wish to buy it either, allowed the peasant to shift to other crops only if he agreed to pay them a large amount, known as tawan, ‘compensation’. The amounts imposed were so large that the peasants had to undergo much hardship only to pay interest on it at the rate of 12% per annum, let alone pay the principal.

Another imposition on the peasants took the form of transferring to them plots out of the indigo factories’ own cultivated lands (zira‘at) charging high rents, under threat of throwing them out of their tenancies if they declined to agree to take these on rent. The planters also collected illegal dues (abwaband imposed fines. Alongside these exactions, the planters made full use of the traditional zamindari practice of begar, forced unpaid or ill-paid labour, requisitioning at will the peasant’s cattle, plough and carts or compelling them to provide labour for their plantations. In other words, the planters tried to throw the entire burden of the crisis caused by competition from synthetic indigo on to the shoulders of the peasants, while safeguarding or even increasing their own profits.

That crisis for the planters eased in 1914 owing to the outbreak of World War I. Germany, the main producer of synthetic indigo, being one of the belligerent powers, the competition from it ceased and planters’ profits from indigo revived, and many of them now began to compel peasants to grow indigo again under the tinkathia system, while underpaying them for the crop by taking into account not the actual produce, but the area sown with the crop. The earlier burdens on the peasants under both sharahbeshi and tawan continued as before, along with forms of begar. Peasants were thus faced with a situation where while prices increased owing to the war, they were themselves subjected to rack renting and forced to grow indigo despite a manipulated low rate of return on it, though raised in their best lands. They faced other kinds of ill treatment as well at the hands of the planters and their staff, including beatings and petty bribery. The planters’ raj was complete and there was no relief for peasants forthcoming from the Bittiah Estate (now under Court of Wards) at the time, which, having given leases to the planters, shared in the gains made out of the oppression of the peasants.

Enter Gandhi

How a delegation from Champaran, attracted by news of the Lucknow session of the Indian National Congress in December 1916, went to the session to draw attention to the Champaran peasants’ plight and how later Raj Kumar Shukla brought Gandhiji from Calcutta to Patna and inexplicably left him there in April 1917 are matters now of traditional lore. It is what followed that is of the utmost importance.

Gandhi’s handling of the Champaran struggle proved to be a model of serious leadership. He was stepping into an area where the peasants had been kept suppressed for so long that no ‘satyagraha’ of the form he had led in South Africa could here be organised. He, therefore, announced that he had come only to study the conditions and collect information, for which he was able to gather a group of intrepid men, including his principal assistant here, Brajkishore Prasad and the future principal Congress leaders of Bihar, Rajendra Prasad and Acharya Kripalani. What he and his group began to do was to move among peasants and just record their grievances. To the end, this was the form and substance of the Champaran satyagraha.

The British authorities knew that this was not as harmless an enterprise as it seemed. The very fact that once an individual peasant could go and record his complaints meant that others would follow him from the ranks of what uptill now had been a subdued demoralised raiyat. On April 16, 1917, the English district magistrate ordered Gandhiji to leave the district, the order being issued under Section 144 of the Criminal Penal Code. Defying the ban, Gandhiji pleaded “guilty” before the district magistrate at Motihari on April 18, ready to face imprisonment for following “the voice of conscience”. It was this combination of moderation with determination that won the day.

The administration, trying to tie down Gandhiji with a long drawn-out case, was flabbergasted at his cutting it short by the “guilty” plea. On the other hand, now not only the volunteers, including the famous Bihar Congress leader Mazharul Haq, but also a crowd of peasants gathered at the court, this being perhaps, the first real peasant demonstration taking place in Champaran. The English magistrate did not know what to do and adjourned the court, releasing Gandhiji on his own assurance of presence. Finally, the government climbed down: On April 21 Gandhiji received intimation from the lieutenant governor of Bihar and Orissa (no less!) of the withdrawal of the proceedings against him with even instructions issued to local officials to assist his “enquiry”.

This success opened the gates to the voicing and recording of complaints from peasants. Local vakils in large numbers joined his band of volunteers. The recording project turned into a real mass movement. As many as 8,000 peasants came and recorded their complaints, defying the planters and their men whose authority visibly crumbled. Peasants also began defiantly to return the high-rent carrying zira‘at lands that planters had imposed on them.

The work of collection of peasants’ complaints took Gandhiji and his volunteers to poverty-stricken villages, where peasants could at last obtain a ray of hope that things could change. Not long afterwards, he received an invitation from another quarter: he was graciously invited to meet a high official of the government, ‘Honourable W. Maude’ at Ranchi on May 10. Gandhiji, as usual, never rejected negotiations and duly met Maude, whom he promised to send a preliminary report on his findings, which he did on May 13. But he politely rejected Maude’s suggestion that he dissolve his team and abandon further pursuit of the enquiry into peasant grievances.

By now the planters and their association had exhausted all their arsenal: threats and inducements to individual peasants, manufactured incidents of violence or arson, canvassing, of English officials as men of their own race and overtures to the great zamindars of Bihar. Gandhiji, on his part, won the moral battle by being ever ready to meet the planters and being unfailingly polite and courteous with them at the personal level. But he never left the side of the peasants.

Finally, the government capitulated. No less a person than E. A. Gait, the lieutenant governor of Bihar and Orissa, along with the chief secretary, H. McPherson, held a long meeting with Gandhiji on June 5 at Ranchi, and here a settlement was worked out. A committee of enquiry, with such broad terms of reference as to cover all the matters that were relevant to peasants’ grievances was to be instituted, the committee to include Gandhiji, as member along with a representative of planters and another of zamindars and three British officials, including the president of the committee. All the evidence that Gandhiji had collected could be placed before it. It was assumed that its recommendations would be honoured by government. In return, Gandhiji at last agreed to terminate his campaign of collecting peasant grievances.

The mass movement at Champaran revolving around the recording of grievances was over. But the actual work of alleviating the grievances had now to be taken up. Again, it is a sign of Gandhiji’s mature leadership that he took up work on this committee with the greatest care and earnestness. He attended all its meetings, presented full evidence before it and was alert in assessing promptly all the proposals that were put before it.

Gandhiji kept the European planters’ transgressions alone as the target of attack. The planters expressed their readiness to reduce the sharahbeshi rent by only 25%, while Gandhiji demanded a reduction of at least 40%. When the official members proposed that the balance of 15% might be met from the revenues of the Bettiah Estate, Gandhiji at once demurred. Clearly, he did not wish to annoy the zamindars of Bihar, who had remarkably remained neutral in the matter. Ultimately, he accepted a 26% reduction in sharahbeshi, this to be borne entirely by the cost of planters.

It is remarkable that the committee was able to present a unanimous, well-written, factually-rich report by October 3, 1917. It practically conceded the truth of all the grievances that Gandhiji’s own “enquiries” had brought out. It recommended the abolition of the tinkathia system and gave freedom to the peasants to grow whatever crop they chose. It denounced the payment by planters for indigo by the area sown and not actual outturn. The reduction of sharahbeshi rent by 26% (as settled by Gandhiji with planters) was approved; and it was recommended that the tawan be abolished, no further payment of principal or interest on this account to be levied on the peasants. All abwabs or additional levies and perquisites as well as fines were held illegal. It recommended that a proclamation to this effect, with penalties to be prescribed, be issued. Above all, the thekadari or village-contracting system by which the planters gained zamindari rights over peasants in villages outside their plantations was to be phased out. Rights in hides were to belong to the peasant owners of the animals, not the planters. The minutes of the committee meetings show how Gandhiji took up every issue of interest to the peasants and argued their case mostly successfully.

The major recommendations of the committee required certain changes to be embodied in law and so the government ordered a law to be prepared in the very month of October 1917, this taking the form of the Champaran Agrarian Act, 1918. It is characteristic of Gandhiji that he also scrutinised the draft Bill and suggested changes in its text to protect the tenants’ interests. Characteristically too, he spent little time in celebrating the huge success he had achieved for the peasants and the poor of Champaran.

The Champaran satyagraha was the first struggle that Gandhiji undertook on Indian soil after his great 20-year long movement for the defence of Indians’ rights in South Africa. It was to be followed quickly by the Ahmedabad workers’ strike against indigenous millowners and by the Kheda satyagraha against revenue enhancements, both in 1918; and then the all-India April satyagraha of 1919 against the Rowlatt Acts and, finally, the non-cooperation and Khilafat movement of 1920-22. But the Champaran satyagraha will always remain as the crucial starting point, the yoking, for the first time, of peasant unrest to the national movement, an assured guarantee for the ultimate success of the latter. As we observe the centenary of the event, one wonders how any tribute could be adequate for the firmness and determination shown by Gandhi and the unflinching resistance offered by the long-oppressed Champaran peasants at his call.

Q.) What do you understand by Gravitational waves?

It is simplest to visualise them using an analogy. One can think of the space-time continuum of general relativity as a malleable rubber sheet. It is bent by heavy bodies such as stars.

The heavier the body, the more is the space-time continuum bent, and the greater is its curvature. Black holes bend it maximally.

Now imagine two such bodies moving towards each other, and finally colliding. On a rubber sheet, two colliding heavy balls would send out ripples as they approach each other. The same thing happens in general relativity.


Gravitational waves are these ripples in the very geometry of space-time. The ripples are tiny when the bodies are far away but gain strength as the bodies approach one other. When they collide, the ripples can have cataclysmic strength. If the two bodies are black holes, space-time is shaken so violently that there is a veritable tsunami in the very fabric of space-time. In a tiny fraction of a second, more energy is emitted than one would obtain by “burning” a few suns, converting their entire mass into energy!


Q.) How does the detection of gravitational waves influence our understanding of our universe?

Ever since the human race started gazing at the night sky and pondering about the nature of heavenly bodies, all our information about the universe has come in the form of electromagnetic waves.

Until the middle of the last century, we only knew what was revealed to us in visible light. By and large, the universe appeared to be rather calm. But then we broadened the frequency bands and looked at the universe using radio waves, through infrared light, through X-rays and through gamma rays. The universe seen at these frequencies, we found, was dramatically different.

Brand new phenomena were seen to unfold. There were huge bursts of energy in the form of jets. There were radio bursts. We saw brand new processes heavenly bodies engage in that had not been even imagined before. As a result, our view of the universe today is very different from what it was half a century ago.

The novel and exotic phenomena are now part of the standard picture. They were always there. But we were blind to them in spite of centuries of careful observations simply because we did not have the appropriate detectors to receive the messengers that the cosmos has been sending.

Gravitational waves are a whole new genre of cosmic messengers, entirely different from our electromagnetic channels. Starting now, we will be blessed with novel, unforeseen opportunities. It is as if a curtain is being drawn back, exposing us to new aspects of the cosmos we inhabit.

We cannot see black hole collisions through any of the electromagnetic frequencies. The only messengers that can inform us of such phenomena are gravitational waves. Over the last quarter of a century, astronomers have pondered a great deal about black holes. But they have been unsure of whether our universe harbours black holes of tens of solar masses. The very first gravitational-wave signal has dispelled that doubt.

Gravitational waves have opened an entirely new branch of astronomy, with various frequency bands of its own. They will reveal to us an untold number of new phenomena. Over the next quarter of a century, our view of the universe is likely to change dramatically.


Q.) What role did India play in Gravitational Wave Detection?

Over several decades, Indian researchers at the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in Pune and the Raman Research Institute in Bengaluru have been deeply involved in gravitational-wave science, making important theoretical contributions to diverse aspects of the problem, ranging from mathematical studies within general relativity to novel aspects of statistics and analysis of large data sets.

* Bala Iyer’s group at the Raman Research Institute (RRI), Bengaluru: pioneered the mathematical calculations used to model the GW signals expected from orbiting black holes and neutron stars.

* Sanjeev Dhurandhar’s group at the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune: did foundational work on developing the data analysis techniques used to detect these weak signals buried deep in the detector noise.

Currently, under the umbrella of the IndIGO consortium, some 60 scientists from nine institutions are members of the LIGO Scientific Collaboration, and the paper reporting the first detection includes 35 authors from these institutions.

These researchers have proposed the creation of a Laser Interferometer Gravitational-wave Observatory in India itself, which will become an integral part of the international network of such observatories, including two in the U.S., one in Europe and one in Japan.

We heard recently that the Union Cabinet has now given its approval, clearing the way for the construction of this observatory. Through a bilateral agreement, the U.S. will provide an advanced detector valued approximately at $120 million and India will invest upwards of Rs.1,200 crore to create the observatory.

The present Indian GW research community has essentially grown out of research programmes these two groups carried out. Over the past decade, the Indian GW community has expanded to a number of educational and research institutions.

·    Chennai Mathematical Institute, the Indian Institute of Science Education and Research (IISER) Thiruvananthapuram, and IISER Kolkata; TIFR Mumbai.


Q.) What benefits can accrue to India by participating in this initiative?

LIGO-India has the potential to impact precision experiments and cutting-edge technology in the country. The project has interfaces with quantum metrology, laser physics and technology, vacuum technologies, optical engineering, sensor technologies, control systems, grid and cloud computing, to list a few. As Beverly Berger of the U.S. National Science Foundation said: “Every single technology they are touching they are pushing and there is a lot of technologies they are touching.”

This initiative represents a truly extraordinary opportunity for development of both fundamental science and technology. On the scientific front, the participating institutions will create human resources not only in physics and astronomy but also in statistics, computational science and data analysis. Through summer schools, workshops and visits to other institutions in the U.S. and Europe, young researchers will be trained in state-of-the-art techniques in all these areas. The opportunities to push forefront technology to new heights are truly immense.

The observatory will feature 4-km-long tunnels in which laser beams bounce back and forth between suspended mirrors. Through the vacuum systems employed in the 4-km-long tunnels, through the powerful lasers used in the interferometer, and through the novel methods that go in the building of the required mirrors and the suspension system that holds them, research and development efforts have already improved technologies used in vacuum systems, optics and material science by several orders of magnitude. It is a true blessing for young researchers to be able to put together, use, and further develop such fine instruments. Through this participation, they will remain at the very cusp of technology in these areas for years to come.


Q.) What lessons can be learnt from India’s successful participation in the LIGO project?

There are three unique aspects of the IndIGO Consortium that have possibly contributed to its success thus far:

* The consortium set goals that projected well ahead into the future, allowing time for a healthy next generation of young researchers to be established. It also allowed time to consolidate expertise scattered across different laboratories in India under a common umbrella. It has also gained international recognition as a channel for Indian researchers abroad to explore possibilities of returning and contributing to the national effort.

* The IndIGO Consortium was an informal collection of researchers devoid of any institutional affiliation. This allowed these researchers to take bold uninhibited steps driven solely by scientific and technological considerations rather than by existing funding and institutional structures. (The IndIGO Consortium enjoyed logistic support from IUCAA to carry out many of its activities and that was formalised recently in an MoU.) Despite being an informal body, the consortium was formally recognised in the global GW community with a membership in the GWIC. The consortium benefited immensely from the cooperative nature of GW endeavours.

* The open and non-institutional nature of the consortium encouraged an influx of experts from all forms of institutional settings, national and international, such as large research laboratories, IISERs, IITs, National Institutes of Technology (NITs), and from other related fields of experimentation and theory. On the other hand, the globally cooperative and collaborative nature of GW science has instilled among the members the spirit of working effectively in a large scientific collaboration.

Note: How the expertise and culture is spreading to other institutes in India: Over the last decade, the Indian GW community, mainly consisting of researchers trained at the research groups in the IUCAA and the RRI, have spread to take up faculty positions at a number of educational and research institutions in India.


Q.) Miscellaneous Points that can be used in Essays

Importance of Persistence:

THE recent detection of gravitational-waves (GWs) by the Laser Interferometer Gravitational-wave Observatory (LIGO), nearly 100 years after they were first recognised by Einstein as a consequence of his general theory of relativity, is the result of one of modern science’s longest campaigns. For more than 40 years, the theoretical world debated back and forth about whether what was predicted was a real phenomenon or just a mathematical artefact with no physical significance.

Role played by Frugal Engineering

Scaling the interferometer to multi-kilometre arm length includes engineering challenges as well. To achieve the required sensitivity, the laser beams must travel in ultra-high vacuum pipes, aligned to millimetre accuracy. While the techniques for building such a large vacuum system were available when LIGO was first proposed, they would have been too expensive for such an uncertain venture. LIGO scientists and engineers worked with commercial companies to develop lower-cost ways to fabricate and install the high vacuum tubes that carry the laser beams. This led to new fabrication techniques for high-vacuum systems, new treatments for the stainless steel used to fabricate them, and even one of the first demonstrations of the use of GPS for precision alignment over long baselines.

Failures as a stepping stone towards success

From the early days of LIGO, it was structured as a two-step programme: first, an initial set of LIGO detectors which would use the best technologies available in the late 1990s, to be followed by a set of advanced detectors incorporating technologies that needed more time for development.

* However the first generation detectors could not detect the GWs.

* But the experience with the first-generation detectors would be extremely valuable in refining the developments needed for the advanced detectors.

* From 2010 to 2015, the initial LIGO detectors were replaced with entirely new, advanced ones.

* These advanced detectors, in very early stage of commissioning, were able to detect the GWs, ending the 100 year old quest for their search.
