Texas History - Fredonian Rebellion

The Fredonian Rebellion (December 21, 1826 – January 23, 1827) was the first attempt by Anglo settlers in Texas to secede from Mexico. The settlers, led by Empresario Haden Edwards, declared independence from Mexican Texas and created the Republic of Fredonia near Nacogdoches. The short-lived republic encompassed the land the Mexican government had granted to Edwards in 1825 and included areas that had been previously settled. Edwards's actions soon alienated these established residents, and the increasing hostilities between them and settlers recruited by Edwards led Victor Blanco of the Mexican government to revoke Edwards's contract.
