During the last days of the Third Reich, as Russia’s Red Army closes in from the east, Adolf Hitler marries his long-time partner Eva Braun in a Berlin bunker during a brief civil ceremony witnessed by Joseph Goebbels and Martin Bormann. Both Hitler and Braun commit suicide the next day, and their corpses are burned in the Reich Chancellery garden.

After refusing induction into the United States Army the day before due to religious reasons, Muhammad Ali is stripped of his heavyweight boxing title. He is found guilty of a felony in refusing to be drafted for service in Vietnam, but he does not serve prison time, and on June 28, 1971, the U.S. Supreme Court reverses his conviction. His stand against the war had made him a hated figure in mainstream America, but in the black community and the rest of the world he had become an icon.

Norwegian ethnographer and adventurer Thor Heyerdahl and his five man crew set out from Peru on a giant balsa wood raft called the Kon-Tiki in order to prove that Peruvian natives could have settled Polynesia. After a 101 day, 4,300 mile (8,000 km) journey, Kon-Tiki smashes into the reef at Raroia in the Tuamotu Islands on August 7, 1947, thus demonstrating that it is possible for a primitive craft to survive a Pacific crossing.

After two days of rumors and denials the Soviet Union admits there was an accident at the Chernobyl nuclear power plant in Ukraine. Reactor number four had suffered a meltdown, sending a plume of radioactive fallout into the atmosphere and over an extensive geographical area.

Italian dictator Benito Mussolini, his mistress Clara Petacci, and fifteen supporters are arrested by Italian partisans in Dongo, Italy while attempting to escape the region in the wake of the collapse of Mussolini’s fascist government.

Their bodies are then trucked to Milan where they are hung upside down on meathooks from the roof of a gas station, then spat upon and stoned until they are unrecognizable.

The Geheime Staatspolizei, aka Gestapo, the official secret police force of Nazi Germany, is established.

In Spain during the Spanish Civil War, the Basque town of Guernica is bombed by the German Luftwaffe, resulting in widespread destruction and casualties. The Basque government reports 1,654 people killed, while later research suggests far fewer deaths, but regardless, Guernica is viewed as an example of terror bombing and other countries learn that Nazi Germany is committed to that tactic. The bombing also becomes inspiration for Pablo Picasso, resulting in a protest painting that is not only his most famous work, but one the most important pieces of art ever produced.
