Introduction
Diu is a city in Diu district in the union territory of Daman and Diu, India. It was the location of the pivotal Battle of Diu in 1509 between Portugal and a combined force of Turkey, Egypt, Venice, the Republic of Ragusa (now known as Dubrovnik) and the then Sultan of Gujarat, Mahmud Begada.
Diu District is an island lying off the south coast of Gujarat's Kathiawar peninsula, separated from the mainland by a tidal creek. It has an area of 40 km², and a population of 44,110 (2001 census). The town of Diu lies at the eastern end of the island, and is known for its fortress and old Portuguese Cathedral. It is also a fishing town. The village of Ghoghla, which lies on the mainland opposite the eastern end of the island, is also part of the union territory.
Diu is listed by the name Dangarvadi on Google Maps.

History
In 1535 Bahadur Shah, the Sultan of Gujarat, concluded a defensive alliance with the Portuguese against the Mughal emperor Humayun, and allowed the Portuguese to construct the Diu Fort and maintain a garrison on the island. The alliance quickly unraveled, and attempts by the Sultans to oust the Portuguese from Diu between 1537 and 1546 failed. The Siege of Diu by the Ottoman Empire in 1538 was unsuccessful to repel the Portuguese. The fortress, completed by Dom João de Castro after the siege of 1545, still stands. The island was occupied by the Indian military on 19 December 1961.
