Constitution of the State of Texas
This is the first constitution of the state of Texas. Ratified by Texas citizens and the U.S. Congress in 1845, it was modified in 1861 to transfer allegiance to the Confederacy. After the Civil War, Texas was required to write a new constitution before it could be readmitted to the United States.
