A single-party state is a political system where only one political party is allowed to hold power, effectively banning all other parties. This means that the government is controlled by a single group, which often leads to limited political pluralism and restricted democratic processes. Citizens typically have little to no choice in political representation, as opposition parties are either outlawed or heavily suppressed. In a single-party state, the ruling party often justifies its dominance by claiming it promotes stability, unity, or national interests. Examples of single-party states include China under the Communist Party, and North Korea led by the Workers' Party. These governments often maintain strict control over media and public discourse to reinforce their authority.
