Final answer:
The decade from 1920 to 1930 was a crucial time in India's journey towards self-rule, with the Congress party and the Muslim League taking separate paths to a constitutional settlement after the British left India.
Step-by-step explanation:
The decade from 1920 to 1930 marked a significant period in India's path towards self-rule, as both the Indian National Congress and the Muslim League pursued separate paths to a constitutional settlement after the British left India. Initially, the Hindus and Muslims within the Congress party worked together towards Indian self-rule. However, growing tensions and fears of Hindu domination led to the formation of the Muslim League in 1906, which sought to address the concerns of the Muslim population and eventually talked about the creation of a separate Muslim state in India.
