To place the events in chronological order from earliest to latest, the sequence is as follows:
- Immediately after Mexico gains independence in 1821, the Mexican government invites Americans to settle in its territory of Texas.
- American settlers in Texas rebel against Mexico and create an independent country called Texas.
- Mexico refuses to recognize the independence of Texas. Meanwhile, independent Texas asked the United States to annex it.
- Even though Mexico warns the United States that annexation would be considered an act of war, the United States annexes Texas anyway.
