Six Flags Over Texas: The Nations That Ruled Texas

Texas has been governed by six sovereign entities since 1821:

1. Spain (until 1821)
2. Mexico (1821–1836)
3. Republic of Texas (1836–1845)
4. United States (1845–1861, 1865–present)
5. Confederate States (1861–1865)
6. United States (restored) (1865–present)

The "Six Flags" theme originates from this history, celebrated at the state capitol and theme parks.
