In 1979, Iranian religious scholar Ayatollah Khomeini forced his way into power with a military coup
Explanation:
Massive Iranian protests and strikes since January 1978 forced Pahlavi to flee the country in January the following year, and a few days later Khomeini returned from exile to Tehran, where he was greeted by millions.
The Pahlavi monarchy officially ended on February 11, 1979, when the Iranian army (formerly loyal to Pahlavi) declared neutrality, and the Iranian revolution itself ended on April 1, when the Islamic Republic of Iran was declared a 98.2% victory after the referendum.
A new constitution was adopted in December of the same year when Khomeini became a supreme leader. His rule is marked by sharp political clashes with the United States, namely the Iraqi attack on Iran.
Originally known as the Advanced Research Projects Agency (ARPA), the agency was created in February 7, 1958 by President Dwight D. Eisenhower in response to the Soviet launching of Sputnik 1 in 1957.
