In the United States, Cinco de Mayo is widely interpreted as a celebration of Mexican culture and heritage, particularly in areas with substantial Mexican-American populations. Chicano activists raised awareness of the holiday in the 1960s, in part because they identified with the victory of indigenous Mexicans over European invaders during the Battle of Puebla. Today, revelers mark the occasion with parades, parties, mariachi music, Mexican folk dancing and traditional foods such as tacos and mole poblano. Some of the largest festivals are held in Los Angeles, Chicago and Houston.
