The centenary of Mahatma Gandhi’s first Satyagraha in India is being marked this April. It was undertaken in the erstwhile undivided Champaran district in northern Bihar. He went there in April, 1917 on learning about the abuses suffered by the cultivators of the district, forced into growing indigo by British planters/estate owners. ‘The Champaran tenant’, informs Gandhi, ‘was bound by law to plant three out of every twenty parts of his land with indigo for his landlord’. This system was called Tinkathia.
