What year was Texas annexed to the United States?

Texas was annexed to the United States in 1845. This significant event followed the Texas Revolution, during which Texas gained independence from Mexico in 1836. The annexation process involved various political negotiations and was driven by Texas’ desire for statehood and security against potential threats. The inclusion of Texas as the 28th state was officially completed when President John Tyler signed the joint resolution for annexation in March 1845, and Texas formally joined the Union later that year in December. This event played a crucial role in shaping U.S. territorial expansion and contributed to the complexities that would later lead to the Mexican-American War.
