Depends on who you are talking about in the Alamo. There was a healthy mix Irishman, Native Americans, Mexicans, a man from Denmark, People from free states others from slave states. Many Mexicans revolted due to the increase centralization of the Mexican government at the time. Within 5 years of the Alamo multiple states would declare independence from Mexico such as the Yucatán, rio grand and Tabasco within 10 years California would declare independence
