Día de la Raza is better known by many people as "Columbus Day". In Mexico this celebration takes on dual meaning. The first part commemorates Christopher Columbus's landing in the Western Hemisphere, ushering in the European immigration that would vastly transform the area. The second reason that Mexican's observe this day is a more specific aspect of the transformation that was seen. Columbus's arrival is viewed as the creation point of the current Mexican race. The majority of people that live in Mexico today are descendant from a mix of Spanish and Indigenous blood, meaning that their specific race didn't come into existence until Columbus showed up.
