History
Early history
Legend has it, that the inhabitants found an "odiong" struck to a tree; thus, the place was called Inodiongan, meaning "struck by an arrow", which later metamorphosed to Odiongan. Historically, Odiongan, as of most of Tablas Island, was first settled by migrant Negrito and Mangyan tribes from the Panay Island to south and Mindoro Island respectively. This was followed shortly by Onhan-speaking settlers from Panay. Around 1810, a group of Bantoanon-speaking people settled in the area in search of a place more suitable for agriculture. However, the settlement founded by these Bantoanons were destroyed and pillaged by Muslimpirates. In 1840, another attempt was made by a different group of Bantoanons; this time, they constructed a fort or cota which protected the settlement from attacks and natural calamities. In 1855, the settlement was officially designated by the Spanish colonial authorities as a pueblo or town. When the Philippine Revolution broke out in 1896, the town joined the cause of the revolutionaries led by Tomas Fiedacan.
Modern history
During the American colonial period in the Philippines, Odiongan faced a number of catastrophes: a cholera epidemic in 1902 killed much of the town's population, a strong typhoon lashed the town in 1908, and famine struck the town in 1914. However, the perseverance and determination of the townsfolk led to the town's continuous existence. In 1940, the town became the seat of the special municipality of Tablas, created by virtue of Commonwealth Act No. 581, which covered the entire island. It remained so throughout the Japanese occupation of the Philippines from 1941-1945. During that time, Odiongan was chosen as the headquarters of the resistance movement in the province, under the leadership of Lt. Col. Enrique Jurado. On 4 September 1943, a Japanese gunboat shelled the town to force the guerrillas out of hiding. This was followed the following month by a landing of Japanese forces from Panay, which massacred people in the various towns of Tablas, Romblon, and Sibuyan, including Odiongan. On 1 October 1946, the special municipality of Tablas was abolished by Republic Act No. 38. The following year, Odiongan was restored to its original jurisdiction as municipality in the province of Romblon.
