March On This Day: Why March 18th is a Key Date for Mexico and the World

When we look back at the March anniversaries, one date stands out, especially for Mexicans: March 18th. It's not just another day on the calendar; it's a day that witnessed events that changed the course of entire nations. If you're looking for a quick guide to understand why this day is so significant, or if you simply want a review of the most impactful moments in history, you've come to the right place. Here's your deep dive into what happened on this day.

1938: Mexico's Declaration of Sovereignty

If there's one event no Mexican forgets when discussing March anniversaries, it's the Oil Expropriation. On March 18, 1938, President Lázaro Cárdenas announced to the world, via radio, the nationalisation of the oil industry. At the time, foreign companies were exploiting the crude oil as if it were their own, ignoring the rulings of Mexican courts. Cárdenas, with a resolve that seems from another era, decreed the legal expropriation of their assets. Petróleos Mexicanos (PEMEX) was born. For many, that was the moment Mexico truly took its place among independent nations. Every March 18th, Mexicans remember that sovereignty isn't asked for; it's exercised.

The World in Motion: Other Key Events on March 18th

But history doesn't stop at the border. If we widen the lens on March anniversaries, the 18th is also a pivotal date in other countries. For example, in 1871, Parisians rose up to establish the Paris Commune, that first workers' government which, although short-lived, sowed the seeds for 20th-century social movements. And speaking of historic milestones, in 1965, Soviet cosmonaut Alexei Leonov became the first human to float in open space. Imagine: tethered to his spacecraft by a thin cord, gazing at Earth from the void. It was a giant leap that seems routine today, but was pure heroism back then.

European politics also has its chapter on March 18th. According to well-documented accounts, in 1990, the German Democratic Republic (East Germany) held its first free elections, a decisive step towards reunification. And going further back, in 1921, the Peace of Riga was signed, ending the war between Poland and Soviet Russia and redrawing the map of Eastern Europe.

Farewells and Arrivals: Notable Figures

Anniversaries are also about goodbyes. On March 18, 1584, Ivan the Terrible, the first Tsar of Russia, passed away—a figure as brutal as he was crucial to his country's history. In the world of science, we lost a visionary in 1893: Alexander Graham Bell, the inventor of the telephone, died on this day. Though the telephone today is almost unrecognisable from his invention, the revolution it brought to human communication is undeniable.

On the flip side, it's also a day that saw the birth of brilliant minds. March 18, 1837, saw the birth of Grover Cleveland, the only US president to serve two non-consecutive terms. And in 1922, the British imprisoned Mahatma Gandhi for sedition, unwittingly fuelling the legend of the man who would free India without firing a shot.

A Quick Rundown of Other March 18th Events

For those who love a fascinating fact or need a speedy historical review of March 18th, here's a list of other events that happened on this day worth remembering:
