Theocracy

The word theocracy comes from the Greek theokratia, meaning "rule of God," and was coined by the Jewish historian Josephus in the first century CE to describe the political order of ancient Israel. In contemporary usage, a theocracy is a state in which sovereignty is understood to belong to a deity and is exercised on that deity's behalf by clergy, religious jurists, or rulers claiming divine sanction. Religious doctrine functions as the supreme source of law, and political legitimacy depends on conformity with that doctrine.

Theocracies differ from states that merely have an established religion (such as the United Kingdom or Denmark, where the church is official but legislation is secular and pluralistic). The defining feature is that clerical bodies or religious law hold binding authority over legislation, judicial decisions, and executive action.

The clearest modern example is the Islamic Republic of Iran, established after the 1979 Revolution under Ayatollah Ruhollah Khomeini. Its 1979 constitution institutionalizes the doctrine of velayat-e faqih (guardianship of the jurist), placing a Supreme Leader drawn from the Shia clergy above the elected president and parliament, with a Guardian Council vetting laws and candidates for compliance with Islamic principles. Vatican City, governed by the Pope as an absolute elective monarch, is also commonly classified as a theocracy, as is Saudi Arabia in many analyses, given the constitutional status of the Qur'an and Sunna and the role of the ulama. The Taliban's Islamic Emirate of Afghanistan (1996–2001 and again from 2021) governs through clerical decree under its interpretation of Sharia.

Historical examples include the Papal States until 1870, Geneva under John Calvin's consistory in the 16th century, and Tibet under the Dalai Lamas before 1959. Theocratic systems generate ongoing tensions in international relations around human rights, religious freedom under Article 18 of the ICCPR, and the rights of women and religious minorities.
