"Cinco de Mayo" Queens Parade at Flushing Park, New York City, USA. Today, It´s considered an important date to celebrate the music, culture, and food of the large Mexican community in USA. Texas, New Mexico, Arizona, and California were once part of the Mexican Republic just 15 years before the battle of 5 de Mayo. But the epic battle was celebrated by all those Mexican-Americans to show solidarity with their mother country. Well, to all of compatriots ¡¡¡Happy 5 de Mayo!!!
