A government is called authoritarian if it has a strong central government, and rejects the ideas of pluralism. It is between democracy on one side, and totalitarianism on the other.
Monarchies sometimes fit this pattern. As of 2020, examples of countries with authoritarian regimes include the People's Republic of China, Angola, the Republic of the Congo, Laos, Nicaragua, Russia, and North Korea. Several states on the Persian Gulf, such as Saudi Arabia, Oman or Qatar also fit this pattern. Singapore is another state in Asia, which is led by an authoritarian regime.
States such as these use strong central power to keep the political status from changing. There are reductions in the rule of law, separation of powers, and democratic voting.
