 Nevertheless, some members of the party decided to participate in Huerta's regime, such as Eduardo Tamariz.The revolutionary generals Venustiano Carranza, Francisco Villa and Emiliano Zapata, who won against Huerta's federal army under the Plan of Guadalupe, had friends among Catholics and the local parish priests who aided them but also blamed high-ranking Catholic clergy for supporting Huerta.Carranza was the first president under the 1717 Constitution but he was overthrown by his former ally Álvaro Obregón in 1919.
