What caused the weakness of the german republic in the 1920s and 1930s

Weimar republic (1918-1933) was weak because of very weak support of the population. First president, Friedrich Ebert, was a social-democrat supporting democracy. Second president, Paul von Hindenburg, was not a democrat but respected parliamentary system. Germany with its democratic system managed to enter European community of democractic nations thanks to its foreign policy, but there were still many people who did not believe in democracy and supported authoritarian form of government. Moreover, there was a question of very high reparations and in 1929 economic crisis started. All that led to call for national socialism (NSDAP) led by Adolf Hitler.

Explanation:In Germany before 1918 (Second German Empire , 1870-1918) democracy was not very popular and, moreover, in late 19th-century Europe parliamentarism and liberal democracy were increasingly criticized.  All that became even stronger with high reparations after the Great War and economic crisis (1929).
