the Treaty of Bucharest. In the following years, the Central Powers (Germany, Austria-Hungary, and the Ottoman Empire), with which Bulgaria had sided, lost World War I, and as a result, Bulgaria had to surrender Western Thrace under the terms of the 1919 Treaty of Neuilly. Western Thrace was under temporary management of the Entente led by French General Charles Antoine Charpy. In late April 1920, as per the San Remo conference with gathered the leaders of the main allies of the Entente powers (except the US), Western Thrace was given to Greece. Throughout the Balkan Wars and World War I, Bulgaria, Greece and Turkey each forced respective minority populations in the Thrace region out of areas they controlled. A large population of Greeks in Eastern Thrace, and Black Sea coastal and southern Bulgaria, was expelled south and west into Greek-controlled Thrace. Concurrently, a large population of Bulgarians was forced from the region into Bulgaria by Greek and Turkish actions. Turkish populations in the area were also targeted by Bulgarian and Greek forces and pushed eastward. As part of the Treaty of Neuilly and subsequent agreements, the status of the expelled populations was legitimized. This was followed by a further population exchange which radically changed the demographics of the region toward increased ethnic homogenization within the territories each respective country was ultimately awarded. This was followed by the large-scale Greek-Turkish population exchanges of 1923 (Treaty of Lausanne), which finalized the reversal of Western and Eastern Thrace region's pre-Balkan War demography. The treaty granted the status of a minority to the Muslims in Western Thrace, in exchange for a similar status for the ethnic Greek minority in Istanbul and the Aegean islands of Imbros and Tenedos. After the German invasion (April 1941), the area was occupied by Bulgarian troops, as part of the triple Axis occupation of Greece, during World War II. During this period (1941-1944) the demographic distribution was further changed, with the arrest of the region's approximately 4,500 Jews by the Bulgarian police and their deportation to death camps administered by Germany. None of them survived. Economy The economy of Thrace in recent years has become less dependent on agriculture. A number of Greek-owned high-tech industries belonging to the telecommunications industry have settled in the area. The Egnatia Odos motorway which passes through Thrace, has contributed to the further development of the region. Tourism is slowly becoming more and more
