Chief Commissioner's Province of Aden in the context of "Bombay Presidency"

The British Raj (/rɑːdʒ/ RAHJ; from Hindustani rāj, 'reign', 'rule' or 'government') was the rule of the British Crown on the Indian subcontinent, lasting from 1858 to 1947. It is also called Crown rule in India, or direct rule in India. The region under British control was commonly called India in contemporaneous usage and included areas directly administered by the United Kingdom, which were collectively called British India, and areas ruled by indigenous rulers, but under British paramountcy, called the princely states. The region was sometimes called the Indian Empire, though not officially. As India, it was a founding member of the League of Nations and a founding member of the United Nations in San Francisco in 1945. India was a participating state in the Summer Olympics in 1900, 1920, 1928, 1932, and 1936.

This system of governance was instituted on 28 June 1858, when, after the Indian Rebellion of 1857, the rule of the East India Company was transferred to the Crown in the person of Queen Victoria (who, in 1876, was proclaimed Empress of India). It lasted until 1947 when the British Raj was partitioned into two sovereign dominion states: the Union of India (later the Republic of India) and Dominion of Pakistan (later the Islamic Republic of Pakistan and People's Republic of Bangladesh in the 1971 Proclamation of Bangladeshi Independence). At the inception of the Raj in 1858, Lower Burma was already a part of British India; Upper Burma was added in 1886, and the resulting union, Burma, was administered as an autonomous province until 1937, when it became a separate British colony, gaining its independence in 1948. It was renamed Myanmar in 1989. The Chief Commissioner's Province of Aden was also part of British India at the inception of the British Raj and became a separate colony known as Aden Colony in 1937 as well.
