Syria became a mandated state of France after the First World War. The border between Turkey and Syria could not be traced until the 1930s because of the dominant state, France. The Sandzak problem that France had to deal with Turkey and other problems played an effective role in this. France, for solving the problems on their behalf and for certain political goals, has placed Armenians and people who executed banditry and were advocates of Kurdish nationalism; who were known to have bad relations with Turkey, in places near the Turkish border. In this article, we will discuss how these elements placed at the border and the smuggling caused by border insecurity during these years have established new settlements and cities in Syria in a very short period of times. This study were used archive documents, period newspapers and other sources in the literature.
