The Demak-Portuguese conflicts were a series of conflicts between the Portuguese Empire and the Demak Sultanate and its allies fought in the East Indies, particularly in the Strait of Malacca, Sea of Java, and the Northern coast of Java, Demak Sultanate started attacking Portuguese forces in the wake of the fall of Malacca in 1511. The first military expedition sent by the Demak sultans was a series of attacks launched against the Portuguese city of Malacca between 1512 and 1521, hoping to restore the overthrown Sultanate of Malacca, but both attacks were failures. However in 1522, after learning that the Portuguese had made an agreement with the Hindu-Sunda Kingdom of Pajajaran, one of Demak enemies, the sultanate attacked the Sundanese Kingdom and secured the region against future Portuguese incursions while establishing trading posts in the coastal area of the region, one of which known today as Jakarta.
