While the Battle of Sakarya enhanced the reputation and image of the TGNA and its army in the country, the most significant aftermath was seen in foreign relations. Most notable was that the countries that sympathize with the Turks signed either friendship treaties or treaties to solve the border disputes with the Ankara government.
The most concrete example of the treaties was the Treaty of Kars signed with the USSR on October 13, 1921 solving border disputes. The Allied Powers were shocked by the Turkish victory and tried to establish peaceful relations with the Turks again.
The French troops left Anatolia by signing a separate treaty, the Treaty of Ankara (Ankara Antlaşması) with the Ankara Government on October 20, 1921.
