国教, or "state religion," refers to a religion that is officially endorsed or recognized by a government. In countries with a state religion, this faith often influences laws, cultural practices, and national identity. Examples of state religions include Buddhism in Thailand and Islam in Saudi Arabia. The concept of 国教 can lead to various implications for religious freedom and pluralism within a nation. In some cases, it may result in preferential treatment for the state religion, while minority religions might face restrictions. This dynamic can shape the social and political landscape of a country significantly.
