Agustín de Iturbide and Vicente Guerrero's plans finally came to fruition as the Mexican Empire declared its independence from Spain, marking the end of Spanish rule and the beginning of a new era for the Mexican people. After months of negotiations and careful planning, the two leaders successfully brought together rival factions and forged an alliance that would shape the course of Mexican history. With the signing of the Treaty of Córdoba, the Mexican Empire was officially born, and Iturbide was hailed as the "Liberator of Mexico".
