The First World War profoundly accelerated the Indian National Movement. Firstly, massive war expenditures led to increased taxes, customs duties, and the introduction of income tax, causing severe economic hardship and price inflation (goods doubled between 1913-1918). This widespread economic distress alienated the common populace. Secondly, the British initiated forced recruitment of soldiers from rural areas, generating deep resentment and anger against colonial rule. Thirdly, crop failures in 1918-19 and 1920-21 resulted in acute food shortages, exacerbated by a deadly influenza epidemic. The government's perceived inadequate response further fueled public discontent. Finally, Indian leaders, having supported Britain, expected significant political concessions towards self-government. However, the post-war constitutional reforms offered were minimal, leading to profound political disillusionment. This betrayal shattered faith in British justice, pushing nationalist leaders and the public towards more assertive and organized anti-colonial movements, intensifying the demand for Swaraj.
