The 1967 Oil Embargo began on June 6, 1967, the second day of the Six-Day War, with a joint Arab decision to deter any countries from supporting Israel militarily. Several Middle Eastern countries eventually limited their oil shipments, some embargoing only the United States and the United Kingdom, while others placed a total ban on oil exports. The Oil Embargo did not significantly decrease the amount of oil available in the United States or any affected European countries, due mainly to a lack of solidarity and uniformity in embargoing specific countries. The embargo was effectively ended on September 1 with the issuance of the Khartoum Resolution.
