Context paragraphs:
Enrique of Malacca: Enrique of Malacca (Spanish: "Enrique de Malaca" ; Portuguese: "Henrique de Malaca" ), was a native of the Malay Archipelago who became a slave of the Portuguese explorer Ferdinand Magellan in the 16th century.  Italian historian Antonio Pigafetta, who wrote the most comprehensive account of Magellan's voyage, named him "Henrique" (which was Hispanicised as "Enrique" in official Spanish documents).  Pigafetta explicitly states that "Henrique" was a native of Sumatra.  According to biographer-philosopher Stefan Zweig, he is the first person to circumnavigate the world.  His name appears as "Henrique", which is Portuguese, and is probably the name given to him at his christening, as he was baptised a Roman Catholic by his Portuguese captors.  His name appears only in Pigafetta's account, in Magellan's Last Will, and in official documents at the "Casa de Contratación de las Indias" of the Magellan expedition to the Philippines.

Magellan Shrine: The Magellan Shrine is a large memorial tower erected in 1866 in honor of the Portuguese explorer Ferdinand Magellan on the Mactan Island of Cebu, the Philippines.  The spot is believed to be the site where Magellan was killed in the 1521 Battle of Mactan.

Walang Sugat: Walang Sugat (literally, "no wound" or "unwounded") is an 1898 Tagalog-language zarzuela (a Spanish lyric-dramatic genre that includes music, singing, and poetry) written by Filipino playwright Severino Reyes.  The music for the original version of the play was written by Filipino composer Fulgencio Tolentino.  "Walang Sugat" was written when the zarzuela became a "potent means" of expressing Filipino nationalism during the Spanish Occupation of the Philippines that followed three centuries of Spanish rule.

History of the Philippines (1521–1898): 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 documented European expedition to the Philippines was that led by Ferdinand Magellan, in the service of the king of Spain.  The expedition first sighted the mountains of Samar at dawn on the 16th 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, at Limasawa Island, Southern Leyte, as is stated in Pigafetta's Primo Viaggio Intorno El Mondo (First Voyage Around the World), Magellan solemnly planted a cross on the summit of a hill overlooking the sea and claimed for the king of Spain possession of the islands he had seen, naming them "Archipelago of Saint Lazarus".

Rajah Humabon: Rajah Humabon, later baptized as Don Carlos, was the Rajah of Cebu at the time of Portuguese explorer Ferdinand Magellan's arrival in the Philippines in 1521.  There is no official record of his existence before the Spanish contact in 1521.  The existing information was written by Magellan's voyage chronicler, Antonio Pigafetta on Humabon and the indigenous Philippine realms that existed prior to Spanish colonisation.

Trinidad (ship): Trinidad was the flagship of Ferdinand Magellan's voyage of circumnavigation.  Unlike Elcano's "Victoria", which returned to Spain sailing across the Indian Ocean, "Trinidad" tried and failed to sail east across the Pacific to New Spain or modern-day Mexico.  "Trinidad" was a "nao" (ship) of 100 tons (or 110 tons, Morrison has both) with square sails on the fore and main masts and a lateen mizzen.  Its original crew was 61.  After Magellan's death and the burning of the "Concepcion", "Victoria" and "Trinidad" (the "San Antonio" and the "Santiago" being lost earlier) reached Tidore on 8 November 1521.  In mid-December both ships attempted to depart loaded with cloves, but "Trinidad" almost immediately began to leak badly.  Inspection showed that the problem was serious.  It was agreed that "Victoria" would leave for Spain and "Trinidad" would remain for repairs.

Armada de Molucca: The Armada de Molucca was the name of the Spanish fleet led by Ferdinand Magellan in the first expedition to sail to the Spice Islands from Europe and the first world circumnavigation.  The fleet sailed from Spain in 1519 across the Atlantic and then Pacific Oceans.  After Magellan's death in the Philippines in 1521, Juan Sebastian Elcano took command of the fleet which arrived in the Spice Islands a few months later, and led the expedition back to Spain across the Indian Ocean where they arrived in 1522.

Santo Niño de Cebú: The Santo Niño de Cebú (Cebuano: "Balaang Bata sa Sugbo" , Filipino: "Batang Banal ng Cebu" , Spanish: "Santo Niño de Cebú" ) is a Roman Catholic title of a statue of the Child Jesus in Cebu City of Philippines.  The image is venerated as miraculous by many Filipino Catholics.  It is one of the oldest Christian relics in the Philippines, originally given in 1521 as a gift by explorer Ferdinand Magellan to Rajah Humabon and his wife when he landed on the island.

Lapu-Lapu: Lapu-Lapu (Baybayin: "ᜎᜉᜓᜎᜉᜓ", Abecedario: "Lápú-Lápú") (fl.  1521) was a ruler of Mactan in Visayas.  Modern Filipino society regards him as the first Filipino hero because he was the first native to resist Spanish colonization.  He is best known for the Battle of Mactan that happened at dawn on April 27, 1521, where he and his soldiers defeated Ferdinand Magellan.  The battle ended up in the killing of Magellan and the end of his expedition and it delayed the Spanish occupation of the islands by over forty years until the expedition of Miguel López de Legazpi in 1564.  Monuments to Lapu-Lapu have been built in Manila and Cebu while the Philippine National Police and the Bureau of Fire Protection use his image.

Estêvão Gomes: Estêvão Gomes, also known in the Spanish versions of his name as Estevan Gómez or Esteban Gómez, (Porto, Kingdom of Portugal, c. 1483 - Paraguay River, 1538), was a Portuguese cartographer and explorer.  He sailed at the service of Castile in the fleet of Ferdinand Magellan, but deserted the expedition before reaching the Strait of Magellan, and returned to Spain in May 1521.  In 1524 he explored present-day Nova Scotia sailing South along the Maine coast.  While historical accounts vary, Gomes may have entered New York Harbor and seen the Hudson River.  Because of his expedition, the 1529 Diogo Ribeiro world map outlines the East coast of North America almost perfectly.
