This agreement was established between the leaders of the independence movement and the Spanish Crown, recognizing Mexico's sovereignty. It laid the groundwork for the establishment of the independent nation of Mexico. The treaty was significant as it acknowledged the efforts of key figures like Agustín de Iturbide, who played a crucial role in the independence struggle.
