Allahabad, officially known as Prayagraj, and also known as Illahabad and Prayag, is a city in the Indian state of Uttar Pradesh. It is the administrative headquarters of Allahabad district—the most populous district in the state and 13th most populous district in India—and the Allahabad division.
Prayagraj is one of the largest cities of the North Indian state of Uttar Pradesh in India. Although Prayaga was renamed Ilahabad in 1575, the name later became Allahabad in an anglicized version in Roman script. The city is situated on an inland peninsula, surrounded by the rivers Ganges and Yamuna on three sides, with only one side connected to the mainland Doab region, of which it is a part. This position is of importance in Hindu scriptures for it is situated at the confluence, known as Triveni Sangam, of the holy rivers. As per Rigveda the Sarasvati River (now dried up) was part of the three river confluence in ancient times. It is one of four sites of the Kumbh Mela, an important mass Hindu pilgrimage.
