The political system where one party holds total control over the government is known as a one-party state. In such systems, the ruling party typically monopolizes political power, limiting or suppressing opposition parties and dissent. This concentration of power can manifest in various ways, including restricted elections, censorship, and the use of coercion to maintain authority. Examples of countries with one-party systems include China and Cuba. These systems often prioritize the party's ideology over democratic principles, leading to challenges in governance and accountability.
