John Calvin established a theocratic state in Geneva, Switzerland, during the 16th century. Under his leadership, Geneva became a center of Protestant reform and the implementation of his theological principles. The governance of the city combined civil and religious authority, reflecting Calvin's belief in the integration of faith and civic responsibility.

A theocracy; for example, the Vatican City, Israel and Iran are, or show aspects of being, theocratic.
The only theocratic governments that exist are in Iran, Vatican City, and Tibet. All of these areas with religion- based governments have been around for a long time, however I am not sure on exact years or dates. There are many countries that have a religion officially recognized as the state religion, but as far as being legitimately theocratic, (where their government decisions are strongly influenced by religion) there are only three.

As of October 2023, there are very few countries with a theocratic government. The most notable example is Iran, which is governed by a system that combines Islamic law with political authority. Other nations, such as Vatican City, also exhibit theocratic elements, but the overall number of fully theocratic states is limited. Generally, theocratic governance is rare in the modern world, with only a handful of countries fitting the definition.
