What is Iran?

Iran is a country in the Middle East with one of the world's oldest and longest-lasting civilizations, with cities and settlements going back to around 5000 BC [1]. It has a rich history of empires, kings, and important cultural contributions that lasted thousands of years.

What happened in modern times?

In the 1900s, Iran had a king called a shah who was friends with Western countries, but many Iranians wanted their country to be independent and make its own choices [2][4]. In 1979, there was a big revolution led by a religious leader named Ayatollah Khomeini that changed Iran into a country ruled by Islamic religious principles instead of a king [3][4].

Why did things change so much?

Iranians struggled to keep their country free and independent while other countries tried to influence them [2]. People disagreed about how Iran should be governed, which eventually led to the revolution that created a new system of government based on Islam [3].

What does this mean today?

The changes from 1979 shaped Iran into what it is today—an Islamic theocracy, which means a government guided by religious Islamic leaders and principles [3]. Understanding this history helps explain why Iran is the way it is now.
