Partition Definition and 307 Threads

The Partition of India was the division of British India into two independent Dominions: India and Pakistan. The two states have since gone through further reorganization: the Dominion of India is today the Republic of India (since 1950); while the Dominion of Pakistan was composed of what is known today as the Islamic Republic of Pakistan (since 1956) and the People's Republic of Bangladesh (since 1971). The partition involved the division of two provinces, Bengal and Punjab, based on district-wide non-Muslim or Muslim majorities. The partition also saw the division of the British Indian Army, the Royal Indian Navy, the Indian Civil Service, the railways, and the central treasury. The partition was outlined in the Indian Independence Act 1947 and resulted in the dissolution of the British Raj, i.e. Crown rule in India. The two self-governing independent Dominions of India and Pakistan legally came into existence at midnight on 15 August 1947.
The partition displaced between 10 and 20 million people along religious lines, creating overwhelming refugee crises in the newly constituted dominions. There was large-scale violence, with estimates of the loss of life accompanying or preceding the partition disputed and varying between several hundred thousand and two million. The violent nature of the partition created an atmosphere of hostility and suspicion between India and Pakistan that affects their relationship to this day.
The term partition of India does not cover the secession of Bangladesh from Pakistan in 1971, nor the earlier separations of Burma (now Myanmar) and Ceylon (now Sri Lanka) from the administration of British India. The term also does not cover the political integration of princely states into the two new dominions, nor the disputes of annexation or division arising in the princely states of Hyderabad, Junagadh, and Jammu and Kashmir, though violence along religious lines did break out in some princely states at the time of the partition. It does not cover the incorporation of the enclaves of French India into India during the period 1947–1954, nor the annexation of Goa and other districts of Portuguese India by India in 1961. Other contemporaneous political entities in the region in 1947—the Kingdom of Sikkim, Kingdom of Bhutan, Kingdom of Nepal, and the Maldives—were unaffected by the partition.Among princely states, the violence was often highly organised with the involvement or complicity of the rulers. It is believed that in the Sikh states (except for Jind and Kapurthala), the Maharajas were complicit in the ethnic cleansing of Muslims, while other Maharajas such as those of Patiala, Faridkot, and Bharatpur were heavily involved in ordering them. The ruler of Bharatpur, in particular, is said to have witnessed the ethnic cleansing of his population, especially at places such as Deeg.
