Proportional representation was were Weimar Germans would vote for a party, and each party would then be allocated seats in the Reichstag. This would mirror the number of people who had voted for the party. This made voting in general more fair, and gives parties a greater chance of getting at least one seat. However, they soon realised it was a disaster as it ended up with dozens of tiny parties, none of the parties were strong enough to get a majority, therefore, there was no government to get its laws passed in the Reichstag, meaning that it all ended crumbling down.
