At the turn of the 20th century, a Russian physiologist made a discovery that would fundamentally change how we understand learning and behavior.

The Mexican Revolution
08/03/2026 | 14 mins.
After Mexico gained independence from Spain in 1821, hopes for democracy gradually gave way to decades of instability and dictatorship.
By the early 20th century, frustration with the long rule of Porfirio Díaz finally erupted into revolution.
What followed was a decade of coups, assassinations, shifting alliances, and civil war involving figures like Pancho Villa and Emiliano Zapata.
The conflict would topple a regime, reshape Mexican society, and produce the modern Mexican state.
Learn more about the Mexican Revolution and why it remains one of the most important upheavals of the 20th century on this episode of Everything Everywhere Daily.
