After the war, Germany had massive debts, inflation, unemployment and food shortages
The Treaty of Versailles also imposed heavy reparations on Germany
After the Kaiser left, Germany were left with the WeirmarRepublic, which was a democracy:
It had a weak government: lots of political parties couldnt agree leading to unstable governments, allowing extremist groups like Nazis gain power
Economic crisis: The country was poor and inflation was terrible, Treaty of Versailles mad things worse
Social division: German people were angry after the war, many didnt want a democracy but a strong leader
Article 48 of Weimar Republic lets the leader take over during emergencies, he could ignore the Reichstag and make laws himself, even take away people rights
This was used by the Nazis to seize power, showing how easily democracy can be destroyed
