Eastern Samar: History
=== Spanish colonial era ===
During his circumnavigation of the globe, Ferdinand Magellan had set foot on the tiny island of Homonhon in the southern part of the province. On March 16, 1521, the area of what is now Eastern Samar is said to be the first Philippine landmass spotted by Magellan and his crew.
In 1596, many names, such as Samal, Ibabao, and Tandaya, were given to Samar Island prior to the coming of the Spaniards in 1596. During the early days of Spanish occupation, Samar was under the jurisdiction of Cebu. Samar and Leyte were later separated from Cebu in 1735. They were split in 1747 but was reversed in 1762 with the approval of the King of Spain, following complaints from the Jesuits. The province of Samar was later established as a distinct province in 1768 after it got separated from the province of Leyte. In 1777, Samar and Leyte split for the last time when it was approved in Madrid in 1786 and had been effective in 1799.

In 1944, combined Filipino-American troops involved in the liberation of the Philippines from Japan built in the town of Guiuan the largest military base in the Pacific. In the same town in 1949, approximately 5,000 Russian refugees escaping from communist China temporarily settled on Tubabao Island until 1951, when they were transferred to Australia and the United States.
==== Foundation ====
Eastern Samar, as a province, was created from Samar province through Republic Act No. 4221 on June 19, 1965. Approved by Congress in 1963, it was authored by Samar congressmen Eladio T. Balite (1st district), Fernando R. Veloso (2nd district), and Felipe J. Abrigo (3rd district). 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 Eastern Samar, aside from the lone district representative, were elected on November 14, 1967, and on January 1, 1968, they officially assumed office.
The capital town of Borongan became a component city by virtue of Republic Act No. 9394 which sought to convert the municipality into a city. The law was ratified on June 21, 2007. However, the cityhood status was lost twice in the years 2008 and 2010 after the LCP questioned the validity of the cityhood law. The cityhood status was reaffirmed after the court finalized its ruling on February 15, 2011, declaring the cityhood law constitutional.
Typhoon Haiyan (Yolanda), one of the strongest typhoons ever recorded, made its first landfall in the coastal town of Guiuan in November 2013.
