The 1979 Oil Crisis was a significant event that led to a sharp increase in oil prices and widespread economic disruption. It was triggered by the Iranian Revolution, which resulted in the overthrow of the Shah and the establishment of an Islamic Republic. This upheaval caused a decrease in oil production in Iran, leading to fears of shortages and panic buying in other countries. As a result, the price of crude oil nearly quadrupled, reaching about $39 per barrel by 1980. The crisis affected many nations, particularly in the United States, where long lines formed at gas stations, and fuel rationing was implemented. The event highlighted the world's dependence on oil and prompted efforts to find alternative energy sources.
