In 1952, Gamal Abdel Nasser led some army officers in a coup d'état against King Farouk, which overthrew the Kingdom of Egypt and established a republic. Nasser's mainstream policy was pan-Arab nationalism and socialism. The ethnic Copts were severely affected by Nasser's nationalization policies, though they represented about 10–20% of the population. In addition, Nasser's pan-Arab policies undermined the Copts' strong attachment to and sense of identity about their Egyptian pre-Arab, and certainly non-Arab identity which resulted in permits to construct churches to be delayed along with Christian religious courts to be closed.
