  • On December 29, 1845, Texas became the 28th state in the United States. Formerly part of Mexico, Texas had been an independent country since 1836.

    Since its independence, Texas had sought annexation by the U.S. However, the process took nearly ten years due to political divisions over slavery. Texas entered the nation as a slave state, and seceded from it 15 years later as part of the Confederate States of America.
