What event triggered the 1973 oil crisis involving Arab members of OPEC?

The event that triggered the 1973 oil crisis involving Arab members of OPEC was the Yom Kippur War. This conflict, which began in October 1973, saw Arab nations, particularly Egypt and Syria, launch a surprise attack on Israel during the Jewish holy day of Yom Kippur. In response to Western support for Israel during the conflict, Arab members of OPEC (Organization of the Petroleum Exporting Countries) imposed an oil embargo against countries perceived as supporting Israel, most notably the United States and several Western nations. This embargo led to a significant reduction in oil supplies, causing oil prices to skyrocket and resulting in widespread economic turmoil and fuel shortages in those countries affected by the embargo. The geopolitical tensions of the war and subsequent OPEC oil embargo marked a significant turning point in global energy politics and the relationship between oil and international affairs.
