The War of the League of the Indies (December 1570–1575) was a military conflict in which a pan-Asian alliance formed primarily by the Sultanate of Bijapur, the Sultanate of Ahmadnagar, the Kingdom of Calicut, and the Sultanate of Aceh, referred to by the Portuguese historian António Pinto Pereira as the "league of kings of India", "the confederated kings", or simply "the league", attempted to decisively overturn Portuguese presence in the Indian Ocean through a combined assault on some of the main possessions of the Portuguese State of India: Malacca, Chaul, Chale fort, and the capital of the maritime empire in Asia, Goa.
