The Treaty of Ankara (1926), also known as the Frontier Treaty of 1926 (Turkish: Ankara Antlaşması), was signed on 5 June 1926 in Ankara by Turkey, the United Kingdom and Mandatory Iraq. 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. 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. 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] [2]
"After the 1926 Treaty, relations between Turkey and Iraq gradually started to improve. In 1928, each side opened legations in the other's capitals and both countries presented their credentials. King Faisal and his ministers made a state visit to the Turkish capital in July 1931, and early in 1932, The Turco-Iraqi Treaties of Residence, Commerce, and Extradition was signed. Although, The Treaty of Bilateral Commerce and Friendship was signed between the Turkish and Iraqi governments in 1932, it was not approved by Britain, which shows the continuation of British control over Iraqi foreign policy after the mandate. In 1937, a non-aggression Treaty was signed with Iraq, called the Saadabad Pact."
