What is happening in Iran, why, and who is involved? In the last 40 years, Iran has endured five convulsions.
The first, the 1978-79 Islamic Revolution, led by Āyatollāh Ruhollah Khomeini, succeeded in his goal of replacing the Shah’s 2,500-year-old Peacock Throne with an Islamic Republic. By 1983, he and his supporters consolidated power, shoving aside moderates. But the economy was wrecked, thanks in part to a costly 1980-88 war with Iraq, triggered by Saddam Hussein’s invasion of Iran. Sour relations with America owing to the 1979-81 hostage crisis didn’t help revive the economy.
