Thrace is a district in the southeastern Balkans, bordering on the Aegean and Black seas. Under Turkish rule from the 14th century, the western portion of Thrace was occupied by Bulgaria in 1912. In 1913, an autonomous Moslem regime briefly ousted the Bulgarians. During its ephemeral existence, this regime issued lithographed stamps, as well as overprints on Turkish, Greek and Bulgarian issues. In 1913 western Thrace was incorporated into Bulgaria, using regular Bulgarian issues. In October 1918, this area was taken from Bulgaria by the Allies, who overprinted Bulgarian stamps for use in the zone. In May 1920, western Thrace was mandated to Greece, and in August, Greece annexed the territory. Eastern Thrace remained in Turkish hands until 1918, when it, too, was occupied by the Allies. Like the western portion of the province, it was turned over to Greece in 1920. After the Greek defeat in the Greco-Turkish War (1922), it was returned to Turkey.
