Manuel Felguérez Barra was a Mexican abstract artist, part of the Generación de la Ruptura that broke with the muralist movement of Diego Rivera and others in the mid 20th century.

Generación de la Ruptura is the name given by art critic Teresa del Conde to the generation of Mexican artists against the established Mexican School of Painting, more commonly called Mexican muralism post World War II. It began with the criticisms of José Luis Cuevas in the early 1950s, followed by others who thought the established art had become dogmatic, formulaic and nationalistic and the artists too deferential to the government. This new generation of artists was not bound by a particular artistic style but was more interested in personal rather than social issues and influenced by a number of international trends in art such as Abstract expressionism. Early reaction to them was strong and negative but by the end of the 1950s, they had succeeded in having their art shown in the major venues of Mexico. The Generación de la Ruptura had influence on other arts in Mexico, such as literature but it did not end the production of murals in Mexico with social and nationalist purposes.
