On what date did Texas officially join the Union?

Texas officially joined the Union on December 29, 1845, marking a significant moment in both Texas and U.S. history. This date is important because it signifies the formal acceptance of Texas as the 28th state in the United States after it had declared independence from Mexico in 1836. The annexation of Texas led to various implications, including tensions that contributed to the Mexican-American War.

Understanding this date is crucial for grasping the historical context of Texas’s transition from an independent republic to statehood, as well as its implications on subsequent events in American history. The other dates listed do not represent the official admission of Texas into the Union, but rather commemorate different milestones in Texas’s history, such as its declaration of independence or other notable events.
