In the early morning hours of November 4, 1979, university students stormed the United States Embassy in Tehran. Although supporters of the Ayatollah Ruhollah Khomeinei, who had taken power from Reza Shah Pahlavi in the Iranian Revolution earlier in the year, they were largely acting of their own accord. They ended up taking hostage the Americans inside the Embassy. Khomeini quickly gave his support to the hostage takers, and America was faced with a new geopolitical crisis, which would last 444 days. All because a group of students came into the United States Embassy.
Which is What Happened Today, November 4, in 1979.
