The partition of Bengal in 1905 further increased the revolutionary movement for Indian independence. The disenfranchisement lead some to take violent action. The British themselves adopted a "carrot and stick" approach in recognition of India's support during the First World War and in response to renewed nationalist demands. The means of achieving the proposed measure were later enshrined in the Government of India Act 1919, which introduced the principle of a dual mode of administration, or diarchy, in which elected Indian legislators and appointed British officials shared power. In 1919, Colonel Reginald Dyer ordered his troops to fire their weapons on peaceful protestors, including unarmed women and children, resulting in the Jallianwala Bagh massacre; which led to the Non-cooperation Movement of 1920–22. The massacre was a decisive episode towards the end of British rule in India. From 1920 leaders such as Mahatma Gandhi began highly popular mass movements to campaign against the British Raj using largely peaceful methods. The Gandhi-led independence movement opposed the British rule using non-violent methods like non-co-operation, civil disobedience and economic resistance. However, revolutionary activities against the British rule took place throughout the Indian subcontinent and some others adopted a militant approach like the Hindustan Republican Association, founded by Chandrasekhar Azad, Bhagat Singh, Sukhdev Thapar and others, that sought to overthrow British rule by armed struggle. The Government of India Act 1935 was a major success in this regard. The All India Azad Muslim Conference gathered in Delhi in April 1940 to voice its support for an independent and united India. Its members included several Islamic organisations in India, as well as 1400 nationalist Muslim delegates. The pro-separatist All-India Muslim League worked to try to silence those nationalist Muslims who stood against the partition of India, often using "intimidation and coercion". The murder of the All India Azad Muslim Conference leader Allah Bakhsh Soomro also made it easier for the pro-separatist All-India Muslim League to demand the creation of a Pakistan. In January 1946, several mutinies broke out in the armed services, starting with that of RAF servicemen frustrated with their slow repatriation to Britain. The mutinies came to a head with mutiny of the Royal Indian Navy in Bombay in February 1946, followed by others in Calcutta, Madras, and Karachi. The mutinies were rapidly suppressed. Also in early 1946, new elections were called and Congress candidates won in eight of the eleven provinces.
