In Mexican history, a plan was a declaration of principles announced in conjunction with a rebellion, usually armed, against the central government of the country (or, in the case of a regional rebellion, against the state government). Mexican plans were often more formal than the pronunciamientos that were their equivalent elsewhere in Spanish America and Spain. Some were as detailed as the United States Declaration of Independence (which in Mexican terms would no doubt have been called the “Plan of Philadelphia”), though some plans merely announced that the current government was null and void and that the signer of the plan was the new president.
Over one hundred plans were declared over all. One compendium, Planes políticos, proclamas, manifiestos y otros documentos de la Independencia al México moderno, 1812-1940, compiled by Román Iglesias González (Mexico City: UNAM, 1998), contains the full texts of 105 plans. About a dozen of these are widely considered to be of great importance in discussions of Mexican history.
