Uttar Pradesh is a state in northern India. With roughly 200 million inhabitants, it is the most populous state in India as well as the most populous country subdivision in the world. It was created on 1 April 1937 as the United Provinces of Agra and Oudh during British rule, and was renamed Uttar Pradesh in 1950.
The state is divided into 18 divisions and 75 districts with the capital being Lucknow. The main ethnic group is the Hindavi people, forming the demographic plurality. On 9 November 2000, a new state, Uttarakhand, was carved out from the state's Himalayan hill region.
The two major rivers of the state, the Ganga and Yamuna, join at Allahabad (Prayagraj) and then flow as the Ganga further east. Hindi is the most widely spoken language and is also the official language of the state, along with Urdu.
