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.
The city is the judicial capital of Uttar Pradesh with Allahabad High Court being the highest judicial body in the state. As of 2011, Allahabad is the seventh most populous city in the state, twelfth in Northern India and thirty-eighth in India, with an estimated population of 1.11 million in the city and 1.21 million in its metropolitan region.
The city lies close to Triveni Sangam, "three-river confluence", original name – Prayag, "place of sacrifice or offering" – which lies at the sangam (confluence) of the Ganga, Yamuna and Sarasvati rivers, a propitious place to conduct sacrifices. It plays a central role in Hindu scriptures. In the early 17th century, Allahabad was a provincial capital in the Mughal Empire under the reign of Jahangir.
Akbarnama mentions that the Mughal emperor Akbar founded a great city in Allahabad. `Abd al-Qadir Bada'uni and Nizamuddin Ahmad mention that Akbar laid the foundations of an imperial city there which was called Ilahabas or Ilahabad. He was said to be impressed by its strategic location and built a fort there, later renaming it Ilahabas by 1584 which was changed to Allahabad by Shah Jahan.
Located in southern Uttar Pradesh, the city's metropolitan area covers 70.5 km (27.22 sq miles). Although the city and its surrounding area are governed by several municipalities, a large portion of Allahabad District is governed by the Allahabad City Council. The city is home to colleges, research institutions and 2 dozen central and state government offices. Allahabad has hosted cultural and sporting events, including the Prayag Kumbh Mela and the Indira Marathon.
