Have women ever been prohibited from voting in Germany during the past 100 years?

Dear crabcakes,

Yes, women were prohibited from voting in Germany before 30 November
1918. On that day, only 20 days after the end of the monarchy, the
Decree on the Elections for the constituent German National Assembly
gave women full suffrage. The Reich Electoral Law adopted this
regulation.

An interesting side note: Although women were not allowed to vote
prior to 1918, they could be members in political parties since 1908.
However, before 1908 several German states had laws explicitly
prohibiting women from membership in political parties. Prussian law,
for example, stated that students, apprentices, insanes and women
could not be members of political organizations...

All the best,
