The first world war, khilafat and …

First World War: The War led to a huge increase in defence expenditure. This was financed by war loans and by increasing taxes. Customs duties were raised and income tax was introduced to raise extra revenue. Prices of items increased during the war years. The prices doubled between 1913 and 1918. The common people were the worst sufferers because of price rise. Forced recruitment of rural people in the army was another cause of widespread anger among people.

Khilafat Movement:The Khilafat issue gave him the opportunity to bring the Hindus and Muslims on a common platform. The Ottoman Turkey was badly defeated in the First World War. There were rumours about a harsh peace treating likely to be imposed on the Ottoman emperor; who was the spiritual head of the Islamic world (the Khalifa). A Khilafat committed was formed in Bombay in March 1919 to defend the Khalifa. This committee had leaders like the brothers Muhammad Ali and Shaukat Ali. They also wanted Mahatma Gandhi to take up the cause to build a united mass action. At the Calcutta session of the Congress in September 1920, the resolution was passed to launch a non-cooperation movement in support of Khilafat and also for swaraj.
Non-Cooperation Movement:In his famous book Hind Swaraj (1909) Mahatma Gandhi declared that British rule was established in India with the cooperation of Indians, and had survived only because of this cooperation. If Indians refused to cooperate, British rule in India would collapse within a year, and swaraj would come. Gandhiji believed that if Indians begin to refuse to cooperate, the British rulers will have no other way than to leave India.
