War of the Indian Sultanates (No America)

The war of the  Indian Sultanates, 1503-1534, saw the European powers starting to exert more influence in the east Indies, as they propped up Hindu states against the rise of muslim sultanates, influenced and backed by the strong muslim trade that existed in the region. The kingdoms of Portugal and Spain put aside their differences to further their interests against the hostile states. In the Treaty of Seville, 1528, the two powers agreed on their respectively spheres of influence in the area, thereby avoiding conflict.

History
The war of the Indian Sultanates began with the seizure of the Malaccan straits, the core of the Malaccan Sultanate, and the expulsion of their leader, by Afonso de Albuquerque in 1503. European explorers and traders had already been hostile to rival muslim trading interests they had met in the far east and India, but this was the largest conquest yet seen of a muslim state.
