History of Cameron County
The county was founded in 1848 and is named for Ewen Cameron, a Captain during the Texas Revolution and in the ill-fated Mier Expedition. During the later 19th century and through World War II, Fort Brown was a US Army outpost here, stimulating the development of the city of Brownsville. Cameron County comprises the Brownsville–Harlingen metropolitan area, as well as the Brownsville-Harlingen-Raymondville combined statistical area, which itself is part of the larger Rio Grande Valley region. The county is home to the SpaceX Starbase spaceport, situated in Boca Chica; it is also the residence of Elon Musk.
