Tzantzismo was a cultural movement in the 1960s, Ecuador. It was founded in Quito in 1962 by Marco Muñoz and Ulises Estrella, and joined by other members throughout the 1960s. They were greatly influenced by other Ecuadorian intellectuals such as Jorge Enrique Adoum, César Dávila Andrade and Agustin Cueva. Tzantzismo was mainly expressed in poetry, and to a lesser extent in stories and theater. This literary revolutionary movement arose in response to a supposed degradation and gentrification in Ecuadorian literature.
