Iran celebrating a revolution that many don’t remember

Today marks the 30th anniversary of a momentous event in history: the Iranian Revolution. Thirty years ago, Iran was a monarchy ruled by the U.S.-backed Shah. The revolution saw the overthrow of the Shah and the coming to power of Islamic clerics under Ayatollah Khomenei. But did you know that almost half the current population of modern-day Iran are under the age of 25? That means that a huge percentage of modern Iran don’t remember the revolution at all, because they weren’t there. But that doesn’t mean the revolution of 1979 has not shaped their lives.
