The Weimar Republic was established in Germany after World War 1 and the abdication of Kaiser Wilhelm II. It was governed by a democratic constitution that guaranteed many civil liberties and rights. The President was elected directly by the people and had power to appoint the Chancellor and rule by emergency decree. The Reichstag was elected using proportional representation which weakened governing coalitions. The constitution's protections of liberties and use of proportional representation contributed to political instability under the Weimar Republic.
