Antonio López de Santa Anna was the president of Mexico during this time. He declared himself a dictator in May 1834. He then got rid of the congress and the state legislatures. Along with several other Mexican states, Coahuila y Tejas (Texas) rebelled. At first, the Texans (Tejanos) wanted the 1824 constitution brought back. But they soon changed to demand independence from Mexico. Bowie went to San Felipe, Texas to take muskets from a Mexican armory. He fought at the Battle of Concepción in October 1835 having been made a colonel of volunteers.
