1. Cinco de Mayo is often associated with Mexican celebrations, but it actually has roots in New Mexico history. On May 5, 1862, the Battle of Puebla took place in Mexico, where the underdog Mexican army defeated the larger and more experienced French army. The victory was seen as a symbol of Mexican resistance against foreign dominance and soon spread throughout the Southwest.

2. In New Mexico, Cinco de Mayo has been celebrated in various ways, from parades and mariachi performances to reenactments of the Battle of Puebla. Many communities also hold fiestas, which combine Catholic and indigenous traditions, and include food, music, and dance.

3. Another significant event that took place on May 5 in New Mexico history is the 1968 student walkout at Albuquerque's West Mesa High School. Latino students were protesting discriminatory treatment and inadequate educational resources, and their actions inspired similar protests in other parts of the country.

4. May 5 is also the anniversary of the dedication of the Rio Grande Bridge near Velarde in 1915. The bridge was a major feat of engineering at the time, spanning over 1,200 feet and allowing for easier transportation and commerce in the region.

5. The New Mexico Department of Veterans Services holds a ceremony every May 5 to honor the service and sacrifice of Hispanic veterans from the state. The event includes a wreath-laying ceremony and patriotic music, and pays tribute to the contributions of Hispanic Americans to the military and their country.
