How WWI's broken promises radicalised India's independence movement

When Great Britain declared war on Germany on 4 August 1914, India — as a Crown dependency — was automatically drawn into the conflict. The subcontinent contributed over a million soldiers to the Allied war effort, fighting across theatres from the Western Front to Mesopotamia and East Africa. This was not a conscript army; India possessed one of the largest voluntary armies in the world at the time, and recruitment surged dramatically in the war's opening months. Punjab alone supplied 13,400 of the 27,522 new recruits enlisted between August and December 1914, reflecting both the martial-class recruitment policies of the colonial army and the genuine economic incentives that drew men to military service.

The Indian National Congress had, through the early twentieth century, evolved from a body of moderate petitioners into an organisation increasingly confident in asserting constitutional rights. The Lucknow Session of 1916 marked a significant moment: Congress passed a resolution demanding that Britain formally declare its 'aim and intention to confer self-government on India at an early date.' Simultaneously, the Lucknow Pact of 1916 — a historic agreement between Congress and the Muslim League — presented a united political front, signalling that Indian political opinion had coalesced around the demand for self-governance. Britain's wartime dependence on Indian manpower and resources made it impossible to dismiss these demands outright, even as it had no genuine intention of accelerating the timeline for Indian self-rule.
