Ayutla (äyōtˈlä) [key], town (1990 pop. 6,214), Guerrero state, S Mexico. Its full name is Ayutla de los Libres [Ayutla of the free]. It is the commercial center for an agricultural, cattle-raising, and lumbering area. The Plan of Ayutla, drawn up in 1854, was a reform program directed toward removing the dictator Santa Anna and convening a constituent assembly to frame a federal constitution. Preparing the way for the War of Reform (1856–61), the plan and the subsequent Revolution of Ayutla (which exiled Santa Anna and established a liberal government) was initially supported by Juan Álvarez, Ignacio Comonfort, Miguel and Sebastián Lerdo de Tejada, and Benito Juárez.
