In 1823 Mexico's southernmost provinces seceded from the union forming a Federation of their own. Texas seceded in a much different fashion, and for different reasons, but with the same intention of being free from Mexico. Thus the two nations were seen as destined for diplomacy but few missions were ever enacted, due to their differences in religion, language, and ethics. Perhaps Texas' greatest influence over the Federation was the encouragement of nationalism, and in fact the strong feeling of nationalism Texas had was growing in The Central American Provinces, triggering the fragmentation of the Federation into five independent states. Trade and relations between Texas and the former UPCA remained at a minimum, but Guatemala continued relations, and in 1845 was considering opening an embassy in Austin, Texas; however, Texas was annexed by the United States before this was possible.
