Texas Annexation Timeline

Learn how the Texas territory changed hands several times before becoming a U.S. state with this helpful timeline! In this two-page social studies worksheet, students will read an annotated timeline that includes key events leading to the 1845 annexation of Texas, beginning with Mexico's independence from Spain in 1821. The timeline also reviews the Mexican-American War that immediately followed the annexation of Texas, and the territory shifts that resulted from that war. Then, on page 2, students will demonstrate their understanding of events surrounding the annexation by answering comprehension and analysis questions using the information from the timeline.
