Polk County, named for James Knox Polk of Tennessee, President of the United States, was created by an act of the first Legislature of the State of Texas, approved on March 30, 1846, out of Liberty County, and embraced that portion from the part designated as the "Northern Division" of said county. It was one of the first of a series of 23 counties, formulated, constituted, and established by the State of Texas, after annexation to the United States.
