In the late 1920s and early 1930s, Stalin insisted on a policy of fighting against non-communist socialist movements everywhere. In Germany, this meant cooperating with the Nazis to defeat the socialists Stalin gave a high priority to an anti-capitalist revolution in Germany. His German Communist Party (KPD) split the working-class vote with the moderate Social Democratic Party. The SPD was the historic Socialist party in Germany, but it now tempered its Marxism to drop revolutionary goals and instead focus on systematic improvement of the condition of the working-class. To succeed, it was necessary for Communists to defeat, discredit, and violently attack the SPD. The Nazi Party was growing rapidly in the early 1930s, and winning support among Protestant workers. Stalin did not see the Nazis as a revolutionary movement, or a threat, but rather as a puppet of financial capitalists. There was some fighting between the KPD and the Nazis, but Stalin designated the SPD has the main enemy in the Parliament and in the street fighting in Germany's industrial cities. In the Reichstag, the KPD delegation would cooperate with the Nazis to defeat SPD proposals. The Nazis and KPD were both trying to overthrow the Weimar regime, which was controlled by a moderate coalition of liberals, Catholics, and the SPD. The Nazis were obviously extremists, and Moscow decided that was a profound weakness such that if they ever came to power, the German government would be seriously weakened and opportunities would brighten for a communist revolution. When Hitler did come to power, he totally destroyed the KPD. A few leaders managed to escape and exile in Moscow; Stalin executed some of them and from the rest to become the eventual leaders of East Germany. Simultaneously in Germany, the Nazis completely destroyed the SPD, imprisoning its leaders or forcing them into exile.
