how does the first world war helped in the independence of india
Answers
Because the British promised that if they got the help of India, they would give independence.
This is despite the fact that India was heavily involved in the First World War as a key contributor to the allied forces and at that time an important part of the British Empire.
Having made huge sacrifices and demonstrated military valour equal to that of European soldiers, Indians widely expected a transition to self-government. These expectations were shared by nationalist leaders such as Mahatma Gandhi
and Muhammad Ali Jinnah
(the founder of Pakistan), but were dashed by the extension of martial law at the end of the conflict.
Following this period, Gandhi launched his first India-wide campaign of civil disobedience against British authority in February 1919. It was not driven by anti-Western or anti-British sentiment per se, but by the pursuit of self-determination. It took a looming Second World War, and the resistance against risking more Indian lives for little tangible return, before nationalist efforts redoubled under the auspices of the Quit India Movement. But the origins of Indian independence can be traced back to the events of the First World War.
