1977 expulsion of Egyptians from Libya
The 1977 expulsion of Egyptians from Libya occurred during heightened tensions between the two countries, when the Libyan leader Muammar Gaddafi accused Egypt of provoking a war to seize Libyan oil fields. With this order, almost all Egyptians living in Libya were required to leave the country by 1 July 1977 or face arrest.
