Eugenio Daza in the context of "Principalía"

Samar (/ˈsɑːmɑːr/ SAH-mar) is the third largest island in the Philippines, with a total population of 1,924,651 as of the 2024 census. It is located in the eastern Visayas and its main language and ethnicity is Waray while its main religion is Roman Catholic. Since 1965, the island is divided into three provinces: Western Samar, Northern Samar, and Eastern Samar. The capitals of these provinces are, respectively, Catarman, Catbalogan, and Borongan., all part of the Eastern Visayas region. In commemoration of the establishment of these provinces, June 19 is celebrated as an annual holiday. The island was first sighted by Ferdinand Magellan on March 16, 1521. Although he did not land, other expeditions were made. Many names, such as Samal, Ibabao, and Tandaya, were given to the island prior to the arrival of the Spaniards in 1596. During the early days of Spanish occupation, Samar was under the jurisdiction of Cebu. In the Philippine–American War, Eugenio Daza led a successful attack against the United States Army, later called the Balangiga massacre. This attack led to the Pacification of Samar and deaths of 2,000 people.

In the American colonization of the Philippines, two uprisings were created; the former was the Pulajan movement which caused massacres in the country. The Battle off Samar was held off the island. In the martial law under Ferdinand Marcos, the Sag-od massacre was caused. After the martial law, the island still has the New People's Army rebellion. Samar is the easternmost island in the Visayas archipelago. The island lies to the northeast of Leyte and lies to the southeast of the Bicol Peninsula on Luzon. To the west is the Samar Sea, and to the north and east of Samar lies the Philippine Sea. The island has the Samar Island Natural Park and has numerous biological discoveries and forests.
