The Egyptians lost and retired to Memphis; the city fell to the Persian control and the Pharaoh was carried off in captivity to Susa in Persia. Roman and Byzantine Periods Rhinocorura (Greek for "Cut-off Noses") and the eponymous region around it were used by Ptolemaid Egypt as a place of banishment for criminals, today known as Arish. After the death of the last Nabatean king, Rabbel II Soter, in 106, the Roman emperor Trajan faced practically no resistance and conquered the kingdom on 22 March 106. With this conquest, the Roman Empire went on to control all shores of the Mediterranean Sea. The Sinai Peninsula became part of the Roman province of Arabia Petraea. Saint Catherine's Monastery on the foot of Mount Sinai was constructed by order of the Emperor Justinian between 527 and 565. Most of the Sinai Peninsula became part of the province of Palaestina Salutaris in the 6th century. Ayyubid Period During the Crusades it was under the control of Fatimid Caliphate. Later, Sultan Saladin abolished the Fatimid Caliphate in Egypt and took this region under his control too. It was the military route from Cairo to Damascus during the Crusades. And in order to secure this route, he built a citadel on the island of Pharaoh (near present Taba) known by his name 'Saladin's Citadel'. Mamluk and Ottoman Periods The peninsula was governed as part of Egypt under the Mamluk Sultanate of Egypt from 1260 until 1517, when the Ottoman Sultan, Selim the Grim, defeated the Egyptians at the Battles of Marj Dabiq and al-Raydaniyya, and incorporated Egypt into the Ottoman Empire. From then until 1906, Sinai was administered by the Ottoman provincial government of the Pashalik of Egypt, even following the establishment of the Muhammad Ali Dynasty's rule over the rest of Egypt in 1805. British control In 1906, the Ottoman Porte formally transferred administration of Sinai to the Khedivate of Egypt, which essentially meant that it fell under the control of the British Empire, who had occupied and largely controlled Egypt since the 1882 Anglo-Egyptian War. The border imposed by the British runs in an almost straight line from Rafah on the Mediterranean shore to Taba on the Gulf of Aqaba. This line has served as the eastern border of Egypt ever since. Israeli invasions and occupation In 1956, Egypt nationalised the Suez Canal, a waterway marking the boundary between Egyptian territory in Africa
