On the 1st of February, 1861, Texas seceded from the United States. They were admitted to the Confederacy the following month.
The event occurred as part of the Secession Convention, where it was also determined that slavery was beneficial, as “the African race” was ‘an inferior and dependent race’.
This document from the day dissolves the state’s association with the United States.
Despite heavy political support to secede, there was also significant opposition, and many Unionists were executed.
Following their defeat in the American Civil War, Texas was restored to the Union in March 1870.
