(Note: The next paragraph was copied from Wikipedia, with small changes) The Rebellion of New Spain (1810–1821) was an armed conflict between the people of New Spain and the Spanish colonial authorities which started on 16 September 1810. The Rebellion was led by New Spaniards, Mestizos and Amerindians who sought independence from Spain. The movement for independence was far from gaining unanimous support among New Spaniards, who became divided between independentists, autonomists and loyalists.
