Some supporters criticized Madero for displaying weakness in not simply seizing the presidency from Diaz, and for failing to pass immediate reforms; however, by following the electoral process, Madero established a liberal democracy and received support from the United States and popular leaders such as Orozco, Villa, and Zapata. Francisco León de la Barra became interim president of Mexico, pending an election to be held in October 1911. Madero won the election decisively and was inaugurated as president in November 1911.
In response to this lack of action, Zapata promulgated the Plan de Ayala in November 1911, declaring himself in rebellion against Madero. He renewed guerrilla warfare in the state of Morelos. Madero sent the Federal Army to deal with Zapata, unsuccessfully.
