The Mexican War of Independence (1810–1821) severed control that Spain had exercised on its North American territories, and the First Mexican Empire was formed from much of the individual territory that had comprised New Spain. The victorious rebels issued a provisional governing document, the Plan de Iguala. This plan reaffirmed many of the ideals of the Spanish Constitution of 1812 and granted equal citizenship rights to all races. In the early days of the country, there was much disagreement over whether Mexico should be a federal republic or a constitutional monarchy. Agustín de Iturbide, who had drafted the Plan of Iguala, became the first monarch, Agustin I after no European royal blood sought to be emperor.
