Many of the modern borders of the Arab World were drawn by European imperial powers during the 19th and early 20th century. However, some of the larger states (in particular Egypt and Syria) have historically maintained geographically definable boundaries, on which some of the modern states are roughly based. The 14th-century Egyptian historian Al-Maqrizi, for instance, defines Egypt's boundaries as extending from the Mediterranean in the north to lower Nubia in the south; and between the Red Sea in the east and the oases of the Western/Libyan desert. The modern borders of Egypt, therefore, are not a creation of European powers, and are at least in part based on historically definable entities which are in turn based on certain cultural and ethnic identifications.
