Why does a multiparty system lead to instability?

A multiparty system can lead to instability because the presence of numerous political parties often results in fragmented legislatures, making it challenging to form a stable government. Coalition governments are frequently necessary, which can be fragile and prone to infighting among parties with differing agendas. Additionally, the competition for power among many parties can lead to polarization and political gridlock, hindering effective governance and decision-making. This environment can foster voter disillusionment and unrest, further destabilizing the political landscape.
