History
Formed in 1846 from Liberty County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Polk County was created from Liberty County on March 30, 1846, though it was not fully organized until July 10, 1846. In 1870, Polk County lost territory to the creation of San Jacinto County, but gained territory from Trinity County in 1875.
