The independence war efforts saw the concurrence of integrated armies composed by Spanish Americans of diverse regions on both sides of the conflict (v.g. Patriots and Royalists), and fighting all over the territories of many future nations. For example, the Army of the Andes which was gathered in the United Provinces of the River Plate fought in Chile, Peru and Ecuador, and later integrated with Simón Bolívar's Army (which itself included troops of future Venezuela, Colombia and Ecuador) to further fight in Peru and the Upper Peru.
