Mexico frees slaves
On this day in 1829, the Guerrero Decree, which abolished slavery throughout the Republic of Mexico except in the Isthmus of Tehuantepec, was issued by President Vicente R. Guerrero.The decree reached Texas on October 16, but Ramón Músquiz, the political chief of the Department of Texas, withheld its publication because it violated colonization laws which guaranteed the settlers security for their persons and property. The news of the decree did alarm the Texans, who petitioned Guerrero to exempt Texas from the operation of the law. On December 2 Agustín Viesca, Mexican minister of relations, announced that no change would be made respecting the status of slavery in Texas. Though the decree was never put into operation, it left a conviction in the minds of many Texas colonists that their interests were not safe under Mexican rule.
