How did Diego Rivera seek to create a national style of art?

From 1913 to 1917 Rivera, influenced by the work of Picasso and others, painted in the cubist style.

In 1917, he shifted into Post-Impressionism.

In 1921, he became involved in the government-sponsored Mexican Mural program. Mexican Muralism is an art movement that stands out because of its political undertones, which are chiefly Marxist in nature.
