The All-Palestine Protectorate, also known as All-Palestine, the Gaza Protectorate or the Gaza Strip, was a short-lived client state with limited recognition, corresponding to the area of the modern Gaza Strip, that was established in the area captured by the Kingdom of Egypt during the 1948 Arab–Israeli War and allowed to run as a protectorate under the All-Palestine Government. The Protectorate was declared on 22 September 1948 in Gaza City, and the All-Palestine Government was formed. The President of the Gaza-seated administration was Hajj Amin al-Husseini, the former chairman of the Arab Higher Committee, while the Prime Minister was Ahmed Hilmi Pasha. In December 1948, just three months after the declaration, the All-Palestine Government was relocated to Cairo and was never allowed to return to Gaza, making it a government in exile. With a further resolution of the Arab League to put the Gaza Strip under the official protection of Egypt in 1952, the All-Palestine Government was gradually stripped of its authority. In 1953, the government was nominally dissolved, though the Palestinian Prime Minister, Hilmi Pasha, continued to attend Arab League meetings on its behalf. In 1959, the protectorate was de jure merged into the United Arab Republic, while de facto turning Gaza into a military occupation area of Egypt.

The All-Palestine Government was established on 22 September 1948, during the 1948 Arab–Israeli War, to govern the Egyptian-controlled territory in Gaza, which Egypt had on the same day declared as the All-Palestine Protectorate. It was confirmed by the Arab League and recognised by six of the then seven Arab League members, with Transjordan being the exception. Though it claimed jurisdiction over the whole of the former Mandatory Palestine, its effective jurisdiction was limited to the All-Palestine Protectorate, which came to be called the Gaza Strip. The President of the protectorate was Hajj Amin al-Husseini, former chairman of the Arab Higher Committee, and the Prime Minister was Ahmed Hilmi Pasha. The legislative body was the All-Palestine National Council.
