Theodore Roosevelt is nominated for the presidency by the Progressive Party, a group of Republicans dissatisfied with the renomination of President William Howard Taft. Also known as the Bull Moose Party, the Progressive platform called for the direct election of U.S. senators, woman suffrage, reduction of the tariff and many social reforms. Roosevelt, who served as the 26th president of the United States from 1901 to 1909, embarked on a vigorous campaign as the party’s presidential candidate. A key point of his platform was the “Square Deal”—Roosevelt’s concept of a society based on fair business competition and increased welfare for needy Americans.

Before a campaign speech in Milwaukee, Wisconsin, presidential candidate Theodore Roosevelt is shot at close range by saloonkeeper John Schrank while greeting the public in front of the Gilpatrick Hotel. Schrank’s .32-caliber bullet, aimed directly at Roosevelt’s heart, failed to mortally wound the former president because its force was slowed by a glasses case and a bundle of manuscript in the breast pocket of Roosevelt’s heavy coat—a manuscript containing Roosevelt’s evening speech. Schrank was immediately detained and reportedly offered as his motive that “any man looking for a third term ought to be shot.”

On November 21, 1912, the Manchester Guardian breaks the news: After three years of digging in the Piltdown gravel pit in Sussex, England, amateur archaeologist Charles Dawson had discovered two skulls that appear to belong to a primitive hominid and ancestor of man, along with a canine tooth, a tool carved from an elephant’s tusk, and fossil teeth from a number of prehistoric animals. Despite muted criticism from a minority of paleontologists, the majority of the scientific community hailed the so-called Piltdown Man discovery as the missing evolutionary link between ape and man.

Bulgaria, Serbia, Greece and Montenegro sign an armistice with Turkey, ending the fighting in the first Balkan War. During the two-month conflict, a military coalition between Greece, Serbia, Bulgaria, and Montenegro—known as the Balkan League—expelled Turkey from all the Ottoman Empire’s former European possessions, with the exception of Constantinople (now Istanbul). In January 1913, a coup d’etat in Turkey led to a resumption of fighting, but the Balkan League was again victorious.
