Northern Samar, officially the Province of Northern Samar, is a province in the Philippines located in the Eastern Visayas region. Its capital is Catarman and is located at the northern portion of the island of Samar. Bordering the province to the south are the provinces of Samar and Eastern Samar. To the northwest, across the San Bernardino Strait is Sorsogon; to the east is the Philippine Sea of the Pacific Ocean and to the west is Samar Sea.
Historian William Henry Scott wrote that a "Samar datu by the name of Iberein was rowed out to a Spanish vessel anchored in his harbor in 1543 by oarsmen collared in gold; while wearing on his own person earrings and chains." In the local epic called siday entitled Bingi of Lawan as written in the article of Scott, Lawan is a prosperous Lakanate in Samar particularly the northernmost part. Datu Hadi Iberein came from the Lakanate of Lawan
In 1614, the Jesuits established a mission residence in Palapag among the Ibabao populace. These missionaries stayed until the late 17th century when they were expelled from the Philippines in 1768 and were replaced by the Franciscans.
As the San Bernardino Strait was along the route of the Spanish galleons plying between Manila and Acapulco, Mexico, a royal port was established in Palapag where the richly laden Manila Galleons were protected from unfavorable winds and troubled seas.
In the early years of the 16th century, shipbuilders were drafted from Palapag to the Cavite shipyards for the construction of galleons and vessels for the conservation of defense of the island. It was also at this time that these recruits ignited the Sumoroy insurrection, which signaled a general uprising against Spain in the Visayas and Mindanao. The insurrection simultaneously flared northward to Albay and southward to the northern coasts of Mindanao and then Cebu. It took over a year before the Spaniards were able to subdue the rebellion.
Later in 1898, when the Americans landed on the beach of Catarman, they organized a revolutionary army led by General Vicente Lukban who fought the invaders armed with cannons and rifles with only bolos and paltiks. Although defeated, they, however, continued to harass the Americans through guerrilla warfare.
During World War II, the people of Northern Samar organized a platoon of volunteers supported by voluntary contributions. The contingent became a part of the Philippine National Guard in Manila. The province also helped the government by purchasing a considerable amount of bonds floated to finance the National Commission for Independence, then organized by Manuel L. Quezon after a coalition of the Nacionalista and Democrata parties were formed.
Congressmen Eladio T. Balite (1st Dist. Samar), Fernando R. Veloso (2nd Dist. Samar), and Felipe J. Abrigo (3rd Dist. Samar), authored Republic Act 4221 which was approved by Congress in 1963. The law, ratified in a plebiscite on June 19, 1965, divided Samar into three: Northern Samar, Eastern Samar and (Western) Samar. The first provincial officials of Northern Samar were elected on November 14, 1967, and on January 1, 1968, they officially assumed office.
