attacks Early in the 16th century, the Bruneian Empire under Sultan Bolkiah attacked the Kingdom of Tondo. Spanish expeditions The following table summarizes expeditions made by the Spanish to the Philippine archipelago. First expedition Although the archipelago may have been visited before by the Portuguese (who conquered Malacca City in 1511 and reached Maluku Islands in 1512), the earliest European expedition to the Philippine archipelago was led by the Portuguese navigator Ferdinand Magellan in the service of King Charles I of Spain in 1521. The Magellan expedition sighted the mountains of Samar at dawn on the 17th March 1521, making landfall the following day at the small, uninhabited island of Homonhon at the mouth of the Leyte Gulf. On Easter Sunday, 31 March 1521, in the island of Mazaua, Magellan planted a cross on the top of a hill overlooking the sea and claimed the islands he had encountered for the King of Spain, naming them Archipelago of Saint Lazarus as stated in "First Voyage Around The World" by his companion, the chronicler Antonio Pigafetta. Magellan sought alliances among the people in the islands beginning with Datu Zula of Sugbu (Cebu), and took special pride in converting them to Christianity. Magellan got involved in the political conflicts in the islands and took part in a battle against Lapulapu, chief of Mactan and an enemy of Datu Zula. At dawn on 27 April 1521, Magellan with 60 armed men and 1,000 Visayan warriors had great difficulty landing on the rocky shore of Mactan where Lapulapu had an army of 1,500 waiting on land. Magellan waded ashore with his soldiers and attacked Lapulapu's forces, telling Datu Zula and his warriors to remain on the ships and watch. Magellan underestimated the army of Lapulapu, and, grossly outnumbered, Magellan and 14 of his soldiers were killed. The rest managed to reboard the ships. The battle left the expedition with too few crewmen to man three ships, so they abandoned the "Concepción". The remaining ships – "Trinidad" and "Victoria" – sailed to the Spice Islands in present-day Indonesia. From there, the expedition split into two groups. The Trinidad, commanded by Gonzalo Gómez de Espinoza tried to sail eastward across the Pacific Ocean to the Isthmus of Panama. Disease and shipwreck disrupted Espinoza's voyage and most of the crew died. Survivors of the Trinidad returned to the Spice Islands, where the Portuguese imprisoned them. The Victoria
