The modern map of the heartland of the Middle East was largely designed by British and French diplomats and strategists (namely Mark Sykes of Britain and Georges Picot of France) during World War I.

The Entente powers defeated the Central powers, the latter comprising first and foremost Germany but also, importantly for the future of the Middle East, the Ottoman empire, which ostensibly controlled the Levant — what today comprises most of what we know as Syria, Jordan, Israel, Palestine and Iraq. The Entente victory essentially allowed for the implementation of Sykes-Picot. It divided the heartland of the Middle East into spheres of influence between the two powers after what they assumed would be victory.

After the war, various Western-dominated conferences solidified the main components of Sykes-Picot into the mandate system, which was officially meant as a mechanism of transition for Middle Eastern peoples and their allotted territories toward independence, but in reality it just replaced Ottoman suzerainty with that of British and French colonial control.

What emerged were largely artificial constructions that reflected British and French competition and imperial (mostly geostrategic and oil pipeline) interests rather than the natural ethnic, religious, economic and geographic contours of the region itself. It was to all intents and purposes the imposition of the Western-based Westphalian nation-state system onto the Middle East. Centuries of pre-existing orientations were cast aside.
