Mural movement

Explanation:

José Vasconcelos was an important Mexican writer, philosopher and politician, who became head of the Secretariat of Public Education (SEP) when Álvaro Obregón became president in 1920.

It was thanks to Vasconcelos that muralists Diego Rivera, José Clemente Orozco, and David Alfaro Siqueiros were given the right to paint the inner walls of the most important public buildings in Mexico, thus, creating the Mexican mural movement.

The Mexican Mural movement refers to the promotion of mural painting  generally with social and political messages in order to reunify the country under the post Revolution government. Thus, these murals had nationalistic, political and social messages so that people could identify themselves as "Mexican".

Thus, it was José Vasconcelos who helped forster the artwork of the Mexican Mural Movement, which sought to foster a sense of nationalism.
