The early aborigines of Romblon were believed to be the Negritos from Panay and the Mangyans from Mindoro. It was in 1582 when the Loarca expeditionists came to the islands and named them collectively as “Lomlon.” A secular clergy administered the province until 1635.

In 1818 Romblon was annexed to the province of Capiz and made into a political and military station. The Americans, who came to rule in 1901, appointed a civil government to run the local affairs. About a century later, in 1917, Romblon became an autonomous province. But it was only in 1947 when this was promulgated by Republic Act. 38.
