Claim: In 1861, Texas joined the Confederate States of America and a year later, martial law was imposed on Central Texas.
Evidence: A slave state before the American Civil War, Texas declared its secession from the U.S. in early 1861, and officially joined the Confederate States of America on March 2 of the same year. Because of these sentiments, the Confederate States of America imposed martial law on Central Texas. The Nueces Massacre, also known as the Massacre on the Nueces, was a violent confrontation between Confederate soldiers and German Texans on August 10, 1862, in Kinney County, Texas.
