  • Texas Independence

    Texas Independence
    "The Texas Declaration of Independence is enacted, creating the Republic of Texas. This independent state is never officially recognized by either Mexico or the United States. The U.S. government refuses to recognize Texas because it does not want to agitate sectional strife; abolitionists oppose Texas's admission to the Union because they know it will become a slave state. But the U.S. does commence secret annexation negotiations with Texas in 1843." -Shmoop.com

    Texas Revolution
    Mexico had been inviting Americans into the Texas territory for decades and soon the white population became many times greater than the Mexican population. This led many of the settlers in Texas to fight for their independence. Although seriously outnumbered and out gunned, the Texans defeated Mexican troops adn gained their independence. Because most Texans were of American descent, Texas later decided to become a part of the United States. This infuriated Mexico.
