The Weimar Republic had a lot of problems. The Treaty of Versailles made things very difficult for the economy. Inflation got completely out of hand. There were political problems because governments ruled only for a very short time, not long enough to be able to make important decisions. There were a lot of radical right and left extremists, for example monarchists (people who wanted back the monarchy) and communists, who believed that all things, especially property, land and money, should be shared. Political parties had their own militias to fight each other.
