Mexican Americans wanted to rejuvenate their cultural heritage.

Explanation:

From Study Island:

As part of the Mexican American artistic and literary renaissance of the 1960s, Chicano artists began painting murals on neighborhood buildings, schools, and churches in an effort to rejuvenate Mexican cultural heritage. This movement took place throughout the Southwest. El Paso and San Antonio are two cities with a strong Chicano mural presence. In fact, in El Paso alone, 100 murals have been painted since the 1960s.
