Eastern Macedonia and Thrace in the context of "Edirne Province"

The Decentralized Administration of Macedonia and Thrace (Greek: Αποκεντρωμένη Διοίκηση Μακεδονίας–Θράκης) is one of the seven decentralized administrations of Greece, consisting of the peripheries of Central Macedonia and Eastern Macedonia and Thrace. The region is centered in the metropolitan city of Thessaloniki in Central Macedonia.

The North Aegean Region (Greek: Περιφέρεια Βορείου Αιγαίου, romanized: Periféreia Voreíou Aigaíou [periˈferia voˈriu eˈʝeu]) is one of the thirteen administrative regions of Greece, and the smallest of the thirteen by population. It comprises the islands of the north-eastern Aegean Sea, called the North Aegean islands, except for Thasos and Samothrace, which belong to the Greek region of Eastern Macedonia and Thrace, and Imbros and Tenedos, which belong to Turkey.

Alexandroupolis (Ἀλεξανδρούπολις, IPA: [aleks̠anˈðɾupolis̠]) or Alexandroupoli (Αλεξανδρούπολη, IPA: [aleks̠anˈðɾupoli]), also known as Alexandrople, is a port city in Greece and the capital of the Evros regional unit, in Greek Thrace. It is the largest city in Eastern Macedonia and Thrace, with a population of 71,751 and is an important port and commercial center for Northern Greece.

The city was first settled by the Ottoman Empire in the 19th century and grew into the fishing village Dedeağaç. In 1873, it became a kaza and one year later was promoted to a sanjak. The city developed into a regional trading center. Later, it became a part of Adrianople Vilayet. During the Russo-Turkish War (1877–1878), the area was briefly captured by the Russians. Ottoman rule ended with the First Balkan War, when the city was captured by Bulgaria in 1912. In the Second Balkan War, Greece took control of the city. With the Treaty of Bucharest (10 August 1913), the city returned to Bulgaria.

Didymoteicho (Greek: Διδυμότειχο, romanized: Didymóteicho IPA: [ðiðiˈmotixo]) is a town located on the eastern edge of the Evros regional unit of Eastern Macedonia and Thrace, in northeastern Greece.

The Odrysian kingdom (/oʊˈdrɪʒən/; Ancient Greek: Βασίλειον Ὀδρυσῶν), also known as Odrysia, was an ancient Thracian state that thrived between the early 5th century BC and the early 3rd / late 1st century BC. Located in present-day Bulgaria, southeastern Romania (Northern Dobruja), northeastern Greece and European Turkey, it was a tribal amalgam dominated by the Odrysians that was the first large political entity to develop in the eastern Balkans.

The Odrysian kingdom was founded by king Teres I, who was exploiting the collapse of the Persian presence in Europe due to the failed invasion of Greece in 480–79. Teres and his son Sitalces pursued a policy of expansion, making the kingdom one of the most powerful of its time. Throughout much of its early history it remained an ally of Athens and even joined the Peloponnesian War on its side. By 400 BC the state showed first signs of fatigue, although the skilled Cotys I initiated a brief renaissance that lasted until his murder in 360 BC.

The history of Bulgaria during World War II encompasses an initial period of neutrality until 1 March 1941, a period of alliance with the Axis powers until 8 September 1944, and a period of alignment with the Allies in the final year of the war. With German consent, Bulgarian military forces occupied parts of the Kingdoms of Greece and Yugoslavia which Bulgarian irredentism claimed on the basis of the 1878 Treaty of San Stefano. Bulgaria resisted Axis pressure to join the war against the Soviet Union, which began on 22 June 1941, but did declare war on Britain and the United States on 13 December 1941. The Red Army entered Bulgaria on 8 September 1944; Bulgaria declared war on Germany the next day.

As an ally of Nazi Germany, Bulgaria participated in the Holocaust, contributing to the deaths of 11,343 Jews from the occupied territories in Greece and Yugoslavia. Though its native 48,000 Jews survived the war, they were subjected to discrimination. However, during the war, German-allied Bulgaria did not deport Jews from the core provinces of Bulgaria. Bulgaria's wartime government was pro-German under Bogdan Filov, Dobri Bozhilov, and Ivan Bagryanov. It joined the Allies under Konstantin Muraviev in early September 1944, then underwent a coup d'état a week later, and under Kimon Georgiev was pro-Soviet thereafter.

Western Thrace (Greek: Δυτική Θράκη, IPA: [ðitiˈci ˈθɾaci]), also known as Greek Thrace or Aegean Thrace, is a geographical and historical region of Greece, between the Nestos and Evros rivers in the northeast of the country. It is the western part of Thrace; East Thrace, which lies east of the river Evros, forms the European part of Turkey, and the area to the north, in Bulgaria, is known as Northern Thrace. Greek Thrace is divided into three regional units (former prefectures): Xanthi, Rhodope and Evros, which together with the Macedonian regional units of Drama, Kavala and Thasos form the region of Eastern Macedonia and Thrace. The largest city of the region is Alexandroupolis.

Inhabited since Paleolithic times, it has been under the political, cultural and linguistic influence of the Greek world since the classical era. Under the Byzantine Empire, Western Thrace was part of the theme of Thrace and then of Macedonia and benefited from its position close to the imperial heartland and became a center of medieval Greek commerce and culture; later, under the Ottoman Empire, a number of Muslims settled there, marking the birth of the Muslim minority of Greece.
