Today, March 2nd, is Texas Independence Day. This holiday, celebrated by Texans, marks the day the Texas Declaration of Independence was adopted officially breaking Texas off from Mexico and creating the Republic of Texas. The date of March 2, 1836 marks Texas declaration of independence, but they had to fight many battles in order to get there. The Texas revolution officially began on October 2, 1835 when the first shots of the Battle of Gonzales were fired. Other battles such as the Battle of the Alamo give Texans pride in their heritage and their tenacity to fight. The fighting would end April 22, 1836, leaving Texas as its own sovereign country. For you trivia buffs out there, Texas is the only U.S. state that was at one time an independent nation, and it was the only state to enter the Union through treaty instead of territorial annexation.
