The Texas Revolution was a rebellion by Anglo-American immigrants as well as Hispanic Texans against the centralist government of Mexico in the Mexican state of Coahuila y Tejas. The uprising was part of a larger revolt against the Centralist Republic of Mexico that included other provinces opposed to the regime of President Antonio López de Santa Anna. The Mexican Congress passed the Tornel Decree, declaring that any foreigners fighting against Mexican troops "will be deemed pirates and dealt with as such, being citizens of no nation presently at war with the Republic and fighting under no recognized flag". Only the province of Texas succeeded in breaking with Mexico, establishing the Republic of Texas. It was eventually annexed by the United States about a decade later.
