Iran, also called Persia, officially the Islamic Republic of Iran, is a country in Western Asia. Its central location in Eurasia and proximity to the Strait of Hormuz give it significant geostrategic importance. Tehran is the capital and largest city.
Iran is home to one of the world’s oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. The Iranian Revolution established the current Islamic Republic in 1979.
Iran’s political system combines elements of a presidential democracy and an Islamic theocracy. Iran is a founding member of the UN, ECO, OIC, and OPEC. It is a major regional and middle power and has large reserves of fossil fuels — including the world’s largest natural gas supply and the third largest proven oil reserves.
The country’s rich cultural legacy is reflected in part by its 22 UNESCO World Heritage Sites. Historically a multi-ethnic country, Iran remains a pluralistic society comprising numerous ethnic, linguistic, and religious groups, the largest being Persians, Azeris, Kurds, Mazandaranis and Lurs.
The police are a constituted body of persons empowered by a state, with the aim to enforce the law, to ensure the safety, health and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers include arrest and the use of force legitimized by the state via the monopoly on violence.
TikTok, known in China as Douyin, is a Chinese video-sharing social networking service owned by ByteDance, a Beijing-based Internet technology company founded in 2012 by Zhang Yiming.
