Ferdinand Magellan was a Portuguese explorer best known for having planned and led the 1519 Spanish expedition to the East Indies across the Pacific Ocean to open a maritime trade route, during which he discovered the interoceanic passage thereafter bearing his name and achieved the first European navigation to Asia via the Pacific. After his death, this expedition was the first to circumnavigate the globe in 1519–22 in the service of Spain.

The Battle of Mactan was fought on a beach in Mactan Island between Spanish forces led by the Portuguese explorer Ferdinand Magellan along with local allies, and Lapulapu, the chieftain of the island, on the early morning hours of April 27, 1521. Magellan, a Portuguese-born commander serving the Spanish Empire who led an expedition that ultimately circumnavigated the world for the first time, commanded a small Spanish contingent in an effort to subdue Mactan led by Lapulapu under the Spanish crown. The sheer number of Lapulapu's forces, compounded with issues on the location and armor, ultimately resulted in a disastrous defeat to the Europeans and the death of Magellan. Surviving members of Magellan's crew continued the expedition under the command of Juan Sebastian de Elcano, who completed the journey in September 1522.
