Weimar Republic was fragile. The Weimar constitution had some inherent defects, which made it unstable and vulnerable to dictatorship. One was proportional representation. This made achieving a majority by any one party a near impossible task, leading to a rule by coalitions. Another defect was Article 48, which gave the President the powers to impose emergency, suspend civil rights and rule by decree. Within its short life, the Weimar Republic saw twenty different cabinets lasting on an average 239 days, and a liberal use of Article 48. Yet the crisis could not be managed. People lost confidence in the democratic parliamentary system, which seemed to offer no solutions.
