Why why did Iranians take 53 Americans hostage at the American embassy in Iran

in 1979?

The Iranians took 53 Americans hostage at the American embassy in Iran in 1979 as a response to the United States' support of the Shah of Iran, who had been overthrown in the Iranian Revolution. The hostage-takers viewed the United States as an imperialist power that was attempting to interfere in Iranian affairs and sought to use the hostages as leverage to gain concessions from the United States.
