In the period 1920-23 France and Britain signed a series of agreements, collectively known as the Paulet–Newcombe Agreement, which created the modern Jordan-Syria and Iraq–Syria borders, as an amendment to what had been designated the "A zone" in the Sykes–Picot Agreement. A more detailed description of the Jordan–Syria border was agreed upon on 31 October 1931.
