The area now known colloquially and officially as UP has undergone several different definitions, nomenclatures and territorial demarcations since the early 19th century, i.e. after the British East India Company had established its supremacy in the Gangetic plains. In 1833 the then Bengal Presidency of the Company was divided into two parts, one of which became Presidency of Agra; in 1836 the Agra area was named North-Western Provinces and placed under a Lieutenant Governor by the Company. In 1877, the two provinces of Agra and Oudh (Oudh was occupied by the Company, in 1858), were placed under one Colonial administrator of the British Crown; he was called Lieutenant Governor of the North-Western Provinces and Chief Commissioner of Oudh. In 1902 the name was changed to United Provinces of Agra and Oudh with Lieutenant Governor of the United Provinces of Agra and Oudh as administrator; in 1921 Lieutenant Governorship was elevated to Governorship and the name of the province was changed to United Provinces of British India. In 1935, the name was shortened to United Provinces. On independence from the British colonial rule in 1947, the princely states of Rampur, Banares and Tehri-Garwal were merged into the United Provinces. In 1950, the name of United Provinces was changed to Uttar Pradesh. In 1999 a separate Himalayan state, Uttaranchal, now known as Uttarakhand, was carved out of Uttar Pradesh.
