Migration to Texas occurred during a period of slavery controversy, with many Americans concerned about the extension of slavery. Realistically, the extension of cotton culture into Texas was no more surprising than the creation of a wheat-growing empire in Minnesota and Dakota.
Increasingly, Mexicans were outnumbered in Texas by Americans. The Texas War of Independence in 1836 was preceded for several years with petitions and conventions during which time Texans demanded changes by the Mexican government. Santa Anna’s move against the Texans resulted in Texas independence. Texas quickly began to request annexation by the United States, which after years of controversy occurred; it became a state in December 1845.
