Bagdadbahn
The Baghdad Railway had progressed as far as Aleppo by 1912, with the branch to Tripoli complete, by the start of World War I; and onwards to Nusaybin by October 1918. The Turks, who sided with Germany and the Central Powers, decided to recover the infrastructure south of Aleppo to the Lebanon in 1917. The Baghdad Railway created opportunity and problems for both sides, being unfinished but running just south of the then defined Syrian/Turkish border.
