What role (effect) did the American Revolution (war against the government) play (have) in Mexican independence (freedom)?

The Revolution also unleashed powerful political, social, and economic forces that would transform the post-Revolution politics and society, including increased participation in politics and governance, the legal institutionalization of religious toleration, and the growth and diffusion of the population. Eleven years after the outbreak of the Mexican War of Independence, Spanish Viceroy Juan de O'Donojú signs the Treaty of Córdoba, which approves a plan to make Mexico an independent constitutional monarchy.
