A one-party system is commonly associated with a totalitarian government. In this system, there is only one political party that is allowed to exist, and all other political parties are banned or prevented from participating in elections. The ruling party exercises total control over the government and the society, and there is no opposition or alternative voices to challenge the ruling party's policies or decisions. This type of government is often characterized by a lack of political freedom, civil liberties, and human rights, as well as a tendency towards authoritarianism and repression.
