Dom Francisco de Almeida, also known as the Great Dom Francisco, was a Portuguese nobleman, soldier and explorer. He distinguished himself as a counsellor to King John II of Portugal and later in the wars against the Moors and in the conquest of Granada in 1492. In 1505 he was appointed as the first governor and viceroy of the Portuguese State of India. Almeida is credited with establishing Portuguese hegemony in the Indian Ocean with his victory at the naval Battle of Diu in 1509. Before Almeida returned to Portugal he lost his life in a conflict with indigenous people at the Cape of Good Hope in 1510. His only son Lourenço de Almeida had previously been killed in the Battle of Chaul.

The State of India, also referred as the Portuguese State of India or simply Portuguese India, was a state of the Portuguese Empire founded six years after the discovery of a sea route to the Indian subcontinent by Vasco da Gama, a subject of the Kingdom of Portugal. The capital of Portuguese India served as the governing centre of a string of military forts and trading posts scattered all over the Indian Ocean.
