Agra ( Hindi: आगरा, Urdu: آ گرہ) aka Akbarabad is a city on the banks of the river Yamuna in the northern state of Uttar Pradesh, India. With a population of 1686976 (2010 est.), it is one of the most populous cities in Uttar Pradesh and the 19th most populous in India. Because 80 percent of the city's sewage flows into Yamuna River, it is 20th most polluted city in India. The city finds mention in the epic Mahābhārata where it was called Agrevaṇa, or 'the border of the forest'. Legend ascribes the founding of the city to Rājā Badal Singh, a Sikarwar Rajput king (circa 1475), whose fort, Badalgarh, stood on or near the site of the present Fort. It achieved fame as the capital of the Mughal emperors from 1526 to 1658 and remains a major tourist destination because of its many splendid Mughal-era buildings, most notably the Tāj Mahal, Agra Fort and Fatehpūr Sikrī, all three of which are UNESCO World Heritage Sites.
