Settlement was still thin when Texas won its independence. Angelina County was organized on April 22, 1846, when Nacogdoches County was divided. The first permanent settler after the county was formed is thought to have been George W. Collins. The population increased quickly thereafter due to the good farming land and to the rivers, which made steamboat transportation possible. The population reached 1,165, of whom 196 were slaves, in 1850. The first county seat was Marion; successively, Jonesville became county seat in 1854, Homer in 1858, and Lufkin in 1892. Lufkin was favored by the route of the Houston, East and West Texas Railway (now the Southern Pacific), which had been built in 1882 from Houston to Shreveport.
