Iraq–Syria border

The Iraqi–Syrian border is the border between Syria and Iraq and runs for a total length of 599 km (372 mi) across Upper Mesopotamia and the Syrian desert, from the tripoint with Jordan in the south-west to the tripoint with Turkey in the north-east.

The Tigris then forms a short 3-4 mile section of the border up to the Turkish tripoint at the confluence with the Khabur river at 37°06′22″N 42°21′26″E / 37.1060°N 42.3572°E / 37.1060; 42.3572.

[2] During the First World War, an Arab Revolt - supported by Britain - succeeded in removing the Ottomans from most of the Middle East.

As a result of the Anglo-French Sykes-Picot Agreement, Britain gained control of the Ottoman vilayets of Mosul, Baghdad and Basra, which it organised into the mandate of Iraq in 1920, with France organising a mandate over Syria.

[4] Most of the border region on both sides was part of the Islamic State of Iraq and the Levant (ISIL) for some years, although its northernmost portion remained under Kurdish control, forming the border between Rojava and Iraqi Kurdistan.
