Public outcry over the president’s use of his wartime powers gave rise to a rebellion that began in Jalapa and ended with Guerrero being forcibly ousted from office at the end of December 1829. Guerrero went into hiding in the mountains of southern Mexico, until he was eventually captured, tried for treason, and executed in February 1831. Nearly all of his decrees—including the one abolishing slavery—were subsequently annulled by Mexico’s national Congress.
