As a result of the Texas Revolution, Texas gained independence and eventually became the 28th state in the United States of America. After Mexico was defeated at the Battle of San Jacinto, Texas became an independent territory, but the independent state could not defend itself against future attacks from Mexico. As a result, Texas petitioned for statehood in the U.S. and was accepted in 1845.
The Texas Revolution stemmed from an increase in immigration from the United States to the Mexican state of Coahuila y Tejas. By 1830, 16,000 U.S. immigrants had settled in the northern territory of Coahuila y Tejas — what would later become Texas. While the majority of citizens in Coahuila y Tejas were people of Hispanic heritage, U.S. immigrants made up one-quarter of the population in the northern territory. This shift in demographic worried Mexican government officials because they feared it would eventually lead to rebellion or an attempt to annex part of the Coahuila y Tejas territory. As a result, the Mexican government passed several laws to limit the power of immigrants in Texas including restricting trade with the United States and banning immigration from the United States. When Generala Antonio Lopez de Santa Anna became Mexico's president, the laws governing Coahuila y Tejas only grew stricter. The Texas Revolution started in October 1835 and ended with Texas' independence on April 21, 1835. Ten years later, Texas joined the United States.
