The Egyptian Sultanate is the name of the Egyptian state under British protection between 1914 and 1922, where British protection of Egypt was announced after the isolation of the English Khedive Abbas Helmi II and the inauguration of his uncle Hussein Kamel Sultana in 1914 at the beginning of the First World War. By changing the name of the Egyptian Khedive of the Egyptian Sultanate ended the nominal sovereignty of the Ottomans over Egypt, and thus symbolized changing the name of the Khedive of the Sultanate to match the title of the head of the Ottoman Empire; In 1917, his brother, Fuad I, was appointed ruler of Egypt until 1922, when Britain unilaterally declared the end of the protection of the United Kingdom over Egypt, known as the "February 28, 1922 Declaration." This date is the date of the establishment of the Egyptian Kingdom. He changed his title to the king of the Egyptian kingdom.
