Treaty of Ankara

The Treaty of Ankara (1926), also known as the Frontier Treaty of 1926, was signed on 5 June 1926 in Ankara by Turkey, the United Kingdom and Mandatory Iraq.^¹ The treaty aimed to solve the so-called "Mosul Question" by determining a mutually satisfactory border between Turkey and Iraq and to regulate their neighbourly relations.^¹ One important aspect of the treaty was that Turkey would have the right to engage in militarily conflict in the border region in the event of it being destabilised.^¹ This sphere of influence which is beyond Turkey's modern boundaries mainly covers the northern part of Iraq, notably the Mosul and Kirkuk region.^¹
