The original Republic of Texas lasted from 1836 to 1846. It gained independence from Mexico before being annexed by the United States ten years later. The annexation led to the Mexican-American War, where Mexican ceded much of its land and recognized Texas as independent. Texas would later secede from the U.S. and join the Confederate States of America in the American Civil War. Presidents Dwight D. Eisenhower and Lyndon B. Johnson were both born in Texas.
