The Bardoli Satyagraha of 1928, in the state of Gujarat, India during the period of the British Raj, was a major episode of civil disobedience and revolt in the Indian Independence Movement. Its success gave rise to Vallabhbhai Patel as one of the greatest leaders of the independence struggle. The background to this movement was provided in 1925 when the taluka of Bardoli in Gujarat suffered from floods and famine, causing crop production to suffer and leaving farmers facing great financial troubles. However, the Government of the Bombay Presidency had raised the tax rate by 30% that year, and despite petitions from civic groups, refused to cancel the rise in the face of the calamities.
