Why did governments often change in the Weimar Republic?

Correct answer: Because coalition governments were weak

Direct answer: Option C is correct. Governments in the Weimar Republic often changed because many political parties competed in parliament and coalition governments were difficult to keep united. A coalition is a government formed by two or more parties when no single party has a majority. The reasoning is step by step: several parties won seats; no party could easily control parliament alone; parties had different aims; disagreements weakened coalitions; when a coalition lost support, the government had to resign or be replaced. This produced political instability and made it harder for citizens to see democracy as strong and effective. Option A is wrong because the Weimar Republic did have a parliament, called the Reichstag. Option B is wrong because Germany was a republic after the emperor abdicated; a king was not ruling the country. Option C is correct because weak coalitions explain frequent changes most directly. Option D is wrong because elections did take place, and election results helped determine the composition of parliament. The problem was not the complete absence of elections but the difficulty of turning divided results into a stable majority. Memory cue: many parties plus no stable majority equals fragile coalition and frequent government change.
