The History of Constitution Day?

In the early 20th century, Mexico was undergoing profound social and political upheaval. The Mexican Revolution (1910–1920) began as a struggle against the long dictatorship of Porfirio Díaz, whose regime favored the wealthy elite and foreign investors while oppressing peasants and workers. Revolutionary leaders called for democratic change, land reform, and labor rights. As the revolution unfolded, the need for a new constitution became central to uniting the country.

A constitutional convention was convened in Querétaro in December 1916. After intense debate, the new Mexican Constitution was promulgated on February 5, 1917. It replaced the earlier Constitution of 1857, which had been liberal but failed to address social inequality and workers' rights. The 1917 Constitution was groundbreaking for its time, influencing future constitutions around the world.

February 5 was declared Constitution Day to commemorate the promulgation of the 1917 Constitution in Querétaro. It became a national public holiday, honoring both the document and the ideals of the revolution — liberty, equality and justice.

In 2006, Mexico's federal government adjusted the observance under the Federal Labor Law, moving the public holiday to the first Monday in February to create a long weekend. This change allowed more citizens to rest and travel while still honoring the Constitution's importance.

Today, the 1917 Constitution remains the foundation of Mexican law and governance, though it has been amended over 700 times to adapt to modern challenges.
