Cass County. Formed from Bowie County land. Created April 25, 1846; organized July 13, 1846. Named in honor of Gen. Lewis Cass (1782-1866), United States soldier and statesman, a strong advocate of annexation of Texas. Important river port city of Jefferson was county seat until Marion County was carved out of Cass in 1860; Linden, near center of county, then became county seat. During wave of sectional patriotism in 1861, the name "Cass" was changed to "Davis", in honor of Jefferson Davis, president of the Confederate states. The original name was restored in 1871.
