The 1936 Summer Olympics (German: "Olympische Sommerspiele 1936"), officially known as the Games of the XI Olympiad, was an international multi-sport event that was held in 1936 in Berlin, Germany. Berlin won the bid to host the Games over Barcelona, Spain, on 26 April 1931, at the 29th IOC Session in Barcelona (two years before the Nazis came to power). It marked the second and final time the International Olympic Committee gathered to vote in a city that was bidding to host those Games. 

To outdo the Los Angeles games of 1932, Adolf Hitler had built a new 100,000-seat track and field stadium, six gymnasiums, and many other smaller arenas. The games were the first to be televised, and radio broadcasts reached 41 countries. Filmmaker Leni Riefenstahl was commissioned by the German Olympic Committee to film the Games for $7 million. Her film, titled "Olympia", pioneered many of the techniques now common in the filming of sports. 

Reich Chancellor Adolf Hitler saw the Games as an opportunity to promote his government and ideals of racial supremacy and antisemitism, and the official Nazi party paper, the "Völkischer Beobachter", wrote in the strongest terms that Jews should not be allowed to participate in the Games. When threatened with a boycott of the Games by other nations, Hitler appeared to allow athletes of other ethnicities from other countries to participate. However German Jewish athletes were barred or prevented from taking part by a variety of methods and Jewish athletes from other countries (notably the US) seem to have been side-lined in order not to offend the Nazi government.
