When the General Colonization Law went into effect in 1824, followed by the 1825 State Colonization Law of Coahuila y Tejas, Robert Leftwich obtained a grant to settle 800 families in Texas.   The grant went through several legal challenges, and later became Robertson's Colony, named for Sterling C. Robertson. The grant encompassed all or parts of 30 present-day Texas counties  Settlers began moving into the area after Fort Gates was established at Gatesville. The Texas state legislature created the county in 1854, naming it after James Coryell.  
Originally, Coryell was to be named Pierce County, but was changed after James' Coryell's death.
