Significance of the Event Commemorated

The event alludes to the enactment of Mexico’s Magna Carta, which has its origins in the Mexican Revolution. At the time, the Mexican Constitution was considered one of the most progressive in the world because of its social and nationalistic content. Since then, it has been the backbone and guide for building and framing Contemporary Mexico.
