Berlin. At the outbreak of World War I in 1914, organization continued, as no one foresaw the war dragging on for four years. Eventually, though, the games were canceled. 1920–1948 After World War I, the German Empire became a republic informally known as Weimar Republic, a change which was reflected in a new flag of Germany that in fact was older than the former one, dating back to early 19th century democratic movements. In the Paris Peace Conference, the outbreak of the war was blamed on Germany and other Central Powers allies. These nations, which by now had new governments, were banned from the 1920 Summer Olympics. While all other banned nations were invited again for the 1924 Summer Olympics, held for the second time in Pierre de Coubertin's home town of Paris, the ban on Germany was not lifted until 1925. This was likely related to French Occupation of the Ruhr and the Rheinland between 1923 and 1925. After 16 years of absence, a new generation of German athletes returned in the 1928 Summer Olympics, scoring second overall. Four years later, the worldwide Great Depression prevented many athletes from competing in the 1932 Games in Los Angeles. Winning only three gold medals, the German team was ranked ninth, though it did finish tied in silver medals, with 12. In the spring of 1931 the 1936 Summer Olympics were awarded to Berlin, 20 years later than originally planned. From 1933 onwards, the Nazi Party ruled Germany, a change being marked by the use of the Nazi flag. In the games, the 348 German athletes not only outnumbered the 310 Americans, but outscored them for the first time in the medal count in which Germany ranked first. Also, German gymnasts Konrad Frey and Alfred Schwarzmann won the most medals, with six and five in total, of which three each were gold, while American Jesse Owens had won four gold medals himself. Leni Riefenstahl documented the games in the film Olympia. The 1940 Summer Olympics as well as the 1944 Summer Olympics were canceled due to World War II. For the 1948 Summer Olympics, with the war a recent memory, Germany and Japan were not invited.
