英埃領スーダン
From 1898, the United Kingdom and Egypt administered all of present-day Sudan as the Anglo-Egyptian Sudan, but northern and southern Sudan were administered as separate [[province]]s of the [[History of Anglo-Egyptian Sudan|condominium]]. In the very early 1920s, the British passed the Closed Districts Ordinances which stipulated that passports were required for travel between the two zones, and permits were required to conduct business from one zone into the other, and totally separate administrations prevailed.
