Eastern Samar is one of the three provinces comprising the main island of Samar. It lies facing the great Pacific Ocean to the east. Its main claim to fame as far as the history of the Philippines is concerned, is that it was in Homonhon Island, Guiuan, Eastern Samar where the Portuguese navigator, Ferdinand Magellan, first landed in March 16, 1521, thereby claiming for the King and Queen of Spain the possession of our dearly beloved land. The positive effects of the re-discovery of the Philippine Islands are her Christianization and the planting of the Catholic Faith.
During the 2nd World War, Eastern Samar became a base for Naval-Air operations in General Douglas MacArthur's drive to push the Japanese occupiers back to their homeland and to their eventual defeat.
