 In the Paris Peace Conference, the outbreak of World War I was blamed on Germany and other Central Powers allies.These nations, even though having new republican governments by now, were not invited to the 1920 Summer Olympics.While all other banned nations except Germany were invited again for the 1924 Summer Olympics, held for the second time in Pierre de Coubertin's home town of Paris, and for the 1924 Winter Olympics, also held in France, the ban on Germany was not lifted until 1925.
