Miguel Hidalgo y Costilla, a Catholic priest, launches the Mexican War of Independence with the issuing of his Grito de Dolores, or “Cry of Dolores.” The revolutionary tract, so-named because it was publicly read by Hidalgo in the town of Dolores, called for the end of 300 years of Spanish rule in Mexico, redistribution of land and racial equality. Thousands of Indians and mestizos flocked to Hidalgo’s banner of the Virgin of Guadalupe, and soon the peasant army was on the march to Mexico City.

The traditional German festival known as Oktoberfest begins on October 12, 1810, when Bavarian Crown Prince Louis, later King Louis I of Bavaria, marries Princess Therese von Sachsen-Hildburghausen. The Bavarian royalty invited the citizens of Munich to attend the festivities, held on the fields in front of the city gates. These famous public fields were named Theresienwiese—”Therese’s fields”—in honor of the crown princess; although locals have since abbreviated the name simply to the “Wies’n.” Horse races in the presence of the royal family concluded the popular event, celebrated in varying forms all across Bavaria.
