Felix Diaz escapes from prison, and plans a coup against Madero, leading to ten days of intense fighting in Mexico City, the "Decena Tragica" (10 Tragic Days). Victoriano Huerta, conspiring with Henry Lane Wilson, the American ambassador under president Woodrow Wilson, betrays Madero. Huerta assumes power in Mexico, as president, and has Madero, his brother, and his vice-president killed "while trying to escape." -

The fighting shifts to a conflict between the followers of Zapata and Carranza. In Morelos, the Zapata's forces are beaten and forced to retreat into the mountains by the Carrancistas. General John J. Pershing leads 10,000 American soldiers into Mexican territory in retaliation for a raid on Columbus, New Mexico by General Francisco "Pancho" Villa. Pershing chases Villa unsuccessfully around the northern states. -

In January, After 11 fruitless months, Pershing is forced to return to the U.S. without ever catching sight of Villa. U.S.-Mexican relations suffer because of the invasion.

When Carranza is elected president (although not recognized as legitimate by the Zapata), it becomes evident that he has no intention of enforcing the new constitution.
