Notable Bahri sultans include Qutuz, who defeated the invading Mongol army of Hulagu at the Battle of Ain Jalut, and Baibars, who finally recaptured the last remnants of the Crusader Kingdom of Jerusalem.
Seeking to rival and ultimately supplant the Ottoman Sultan, Muhammad Ali implemented a rapid modernization and militarization program, and expanded Egypt's borders south into Sudan and north into Syria.
Muhammad Ali's grandson, Ismail I, acceded to the Egyptian throne in 1863 and immediately set about achieving his grandfather's aims, though in a less confrontation manner.
The subsequent Orabi Revolt resulted in Great Britain invading Egypt in 1882 on the invitation of Khedive Tewfik, and beginning its decades long occupation of the country.
From 1882 onwards, Egypt's status became deeply convoluted: officially a province of the Ottoman Empire, semi-officially a virtually independent state with its own monarchy, armed forces, and territorial possessions in Sudan, and for practical purposes a British puppet.
Symbolizing the official end of Ottoman rule, Hussein Kamel took the title Sultan as did his brother Fuad I who succeeded him in 1917, though in reality Egypt remained under British domination.
Another reason offered for the change in title, is that it reflected the growing secularization of Egypt at the time, as sultan has Islamic overtones, whereas the Arabic word for king, malik, does not.
However, since the revolutionaries had already decided to abolish the Egyptian monarchy after a brief period of consolidating their hold on power, they determined that it would be an idle gesture and Farouk's son was duly declared King Fuad II.
