East Thrace in the context of "Marmara region"

Southeast Europe or Southeastern Europe is a geographical sub-region of Europe, consisting primarily of the region of the Balkans, as well as adjacent regions and archipelagos. There are overlapping and conflicting definitions of the region, due to political, economic, historical, cultural, and geographical considerations.

Sovereign states and territories that may be included in the region are Albania, Bosnia and Herzegovina, Bulgaria, Croatia (alternatively placed in Central Europe), Greece (alternatively placed in the broader region of Southern Europe), Kosovo, Montenegro, North Macedonia, Romania (alternatively placed in Eastern Europe), Serbia, and the European part of Turkey (alternatively placed in the broader region of Southern Europe, also in Western Asia with the rest of the country). Sometimes, Cyprus (most often placed in West Asia), Hungary (most often placed in Central Europe), Moldova (most often placed in Eastern Europe), and Slovenia (most often placed in Central Europe) are also included due to cultural or historical factors and affiliation.

Turkey, officially the Republic of Türkiye, is a country mainly located in Anatolia in West Asia, with a relatively small part called East Thrace in Southeast Europe. It borders the Black Sea to the north; Georgia, Armenia, Azerbaijan, and Iran to the east; Iraq, Syria, and the Mediterranean Sea to the south; and the Aegean Sea, Greece, and Bulgaria to the west. Turkey is home to over 85 million people; most are ethnic Turks, while Kurds are the largest ethnic minority. Officially a secular state, Turkey has a Muslim-majority population. Ankara is Turkey's capital and second-largest city. Istanbul is its largest city and economic center. Other major cities include İzmir, Bursa, and Antalya.

First inhabited by modern humans during the Late Paleolithic, present-day Turkey was home to various ancient peoples. The Hattians were assimilated by the Hittites and other Anatolian peoples. Classical Anatolia transitioned into cultural Hellenization after Alexander the Great's conquests, and later Romanization during the Roman and Byzantine eras. The Seljuk Turks began migrating into Anatolia in the 11th century, starting the Turkification process. The Seljuk Sultanate of Rum ruled Anatolia until the Mongol invasion in 1243, when it disintegrated into Turkish principalities. Beginning in 1299, the Ottomans united the principalities and expanded. Mehmed II conquered Constantinople (modern-day Istanbul) in 1453. During the reigns of Selim I and Suleiman the Magnificent, the Ottoman Empire became a global power. From 1789 onwards, the empire saw major changes, reforms, centralization, and rising nationalism while its territory declined.

The Greeks in Turkey constitute a small population of Greek and Greek-speaking Eastern Orthodox Christians who mostly live in Istanbul, as well as on the two islands of the western entrance to the Dardanelles: Imbros and Tenedos (Turkish: Gökçeada and Bozcaada). Greeks are one of the four ethnic minorities officially recognized in Turkey by the 1923 Treaty of Lausanne, together with Jews, Armenians, and Bulgarians.

They are the remnants of the estimated 200,000 Greeks who were permitted under the provisions of the Convention Concerning the Exchange of Greek and Turkish Populations to remain in Turkey following the 1923 population exchange, which involved the forcible resettlement of approximately 1.2 million Greeks from Anatolia and East Thrace and of half a million Turks from all of Greece except for Western Thrace. After years of persecution (e.g. the Varlık Vergisi, the Istanbul Pogrom and the 1964 expulsion of Istanbul Greeks), emigration of ethnic Greeks from the Istanbul region greatly accelerated, reducing the Greek minority population from 119,822 before the 1955 pogrom to about 7,000 by 1978. The 2008 figures released by the Turkish Foreign Ministry places the current number of Turkish citizens of Greek descent at the 3,000–4,000 mark.However, according to the Human Rights Watch the Greek population in Turkey is estimated at 2,500 in 2006. The Greek population in Turkey is collapsing as the community is now far too small to sustain itself demographically, due to emigration, much higher death rates than birth rates and continuing discrimination.

The Eastern Mediterranean is a loosely delimited region comprising the easternmost portion of the Mediterranean Sea, and well as the adjoining land—often defined as the countries around the Levantine Sea. It includes the southern half of Turkey's main region, Anatolia; its smaller Hatay Province; the island of Cyprus; the Greek Dodecanese islands; and the countries of Egypt, Israel, Jordan, Palestine, Syria and Lebanon.

Its broadest uses can encompass the Libyan Sea (thus Libya), the Aegean Sea (thus European Turkey and the mainland and islands of Greece), and the Ionian Sea (thus southern Albania in Southeast Europe) and can extend west to Italy's farthest south-eastern coasts. Jordan is climatically and economically part of the region.

The Turkish Straits (Turkish: Türk Boğazları) are two internationally significant waterways in northwestern Turkey. The Straits create a series of international passages that connect the Aegean and Mediterranean seas to the Black Sea. They consist of the Dardanelles and the Bosphorus. The straits are on opposite ends of the Sea of Marmara. The straits and the Sea of Marmara are part of the sovereign sea territory of Turkey and are treated as Turkish internal waters.

Located in the western part of the landmass of Eurasia, the Straits are conventionally considered the boundary between the continents of Europe and Asia, as well as the dividing line between European Turkey and Asian Turkey. Owing to their strategic importance in international commerce, politics, and warfare, the Straits have played a significant role in European and world history. Since 1936, they have been governed in accordance with the Montreux Convention.

The Balkan Wars were two conflicts that took place in the Balkan states in 1912 and 1913. In the First Balkan War, the four Balkan states of Greece, Serbia, Montenegro and Bulgaria declared war upon the Ottoman Empire and defeated it, in the process stripping the Ottomans of their European provinces, leaving only Eastern Thrace under Ottoman control. In the Second Balkan War, Bulgaria fought against the other four combatants of the first war. It also faced an attack from Romania from the north. The Ottoman Empire lost the bulk of its territory in Europe. Although not involved as a combatant, Austria-Hungary became relatively weaker as a much enlarged Serbia pushed for union of the South Slavic peoples. The war set the stage for the July crisis of 1914 and as a prelude to the First World War.

By the early 20th century, Bulgaria, Greece, Montenegro and Serbia had achieved independence from the Ottoman Empire, but large elements of their ethnic populations remained under Ottoman rule. Over the course of the Macedonian Struggle these states fought for influence between themselves and the Ottoman government within Ottoman Macedonia, during which their governments came under the control of nationalists. In 1912, these countries united to formed the Balkan League. The First Balkan War began on 8 October 1912, when the League member states attacked the Ottoman Empire, and ended eight months later with the signing on 30 May 1913 of the Treaty of London negotiated together with the Great Powers. The Great Powers - particularly Italy and Austria-Hungary -- included independence for Albania in the Treaty. The Second Balkan War began on 16 June 1913, when Bulgaria, dissatisfied with its allotment of territory from Macedonia, attacked its former Balkan League allies. The combined forces of the Serbian and Greek armies, with their superior numbers repelled the Bulgarian offensive and counter-attacked by invading Bulgaria from the west and the south. Romania, having taken no part in the first conflict, had intact armies to strike with and invaded Bulgaria from the north in violation of a peace treaty between the two states. The Ottoman Empire also attacked Bulgaria and advanced in Thrace, regaining Adrianople. In the resulting Treaty of Bucharest, Bulgaria managed to retain most of the territories it had gained in the First Balkan War. However, it was forced to cede the ex-Ottoman south part of Dobruja province to Romania.

The Sea of Marmara, also known as the Sea of Marmora or the Marmara Sea, is a small inland sea entirely within the borders of Turkey. It links the Black Sea and the Aegean Sea via the Bosporus and Dardanelles straits, separating Turkey's European and Asian sides. It has an area of 11,350 km (4,380 sq mi), and its dimensions are 280 km × 80 km (174 mi × 50 mi). Its greatest depth is 1,370 m (4,490 ft).

The Bosporus or Bosphorus Strait (/ˈbɒspərəs, ˈbɒsfərəs/ BOSS-pər-əs, BOSS-fər-əs; Turkish: İstanbul Boğazı, lit. 'Istanbul strait', colloquially Boğaz) is a natural strait and an internationally significant waterway located in Turkey which is straddled by the city of Istanbul. The Bosporus connects the Black Sea to the Sea of Marmara and forms one of the continental boundaries between Asia and Europe. It also divides Turkey by separating Asia Minor from Thrace. It is the world's narrowest strait used for international navigation.

Most of the shores of the Bosporus Strait, except for the area to the north, are heavily settled, with the city of Istanbul's metropolitan population of 17 million inhabitants extending inland from both banks.

Strandzha (Bulgarian: Странджа, also transliterated as Strandja, pronounced [ˈstrand͡ʒɐ]; Turkish: Istranca [ɯstɾand͡ʒa], or Yıldız [jɯɫdɯz]) is a mountain massif in southeastern Bulgaria and East Thrace, the European part of Turkey. It is in the southeastern part of the Balkans between the plains of Thrace to the west, the lowlands near Burgas to the north, and the Black Sea to the east. Its highest peak is Mahya Dağı (Bulgarian: Махиада, Mahiada) (1,031 m or 3,383 ft) in Turkey, while the highest point on Bulgarian territory is Golyamo Gradishte (Bulgarian: Голямо Градище) (710 m or 2,329 ft). The total area is approximately 10,000 km (3,861 sq mi).

Thrace (/θreɪs/, thrayss; Bulgarian: Тракия, romanised: Trakiya; Greek: Θράκη, romanised: Thráki; Turkish: Trakya) is a geographical and historical region in Southeast Europe roughly corresponding to the province of Thrace in the Roman Empire. Bounded by the Balkan Mountains to the north, the Aegean Sea to the south, and the Black Sea to the east, it comprises present-day southeastern Bulgaria (Northern Thrace), northeastern Greece (Western Thrace), and the European part of Turkey (East Thrace). Lands also inhabited by ancient Thracians extended in the north to modern-day Northern Bulgaria and Romania and to the west into Macedonia.

The Middle East is a geopolitical region encompassing the Arabian Peninsula, Egypt, Iran, Iraq, the Levant, and Turkey.

The term came into widespread usage by Western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai region) and all of Turkey (including East Thrace).

This list of European countries by population comprises the 51 countries and 5 territories and dependencies in Europe, broadly defined, including Cyprus, Kazakhstan, Turkey, and the countries of the Caucasus.

The most populous European country is Russia, with a population of over 144 million. Turkey, with a population of about 85 million, has most of its population living within its Asian part; though within its territory in Europe, some one-tenth of its population is situated. Excluding Turkey, Germany is the second-most populous country on the continent, with a population of about 84 million.

Bulgarians in Turkey (Turkish: Türkiye'deki Bulgarlar, Bulgarian: Българи в Турция) form a minority of Turkey. They are Bulgarian expatriates in Turkey or Turkish citizens who were born there of full or partially Bulgarian descent. People of Bulgarian ancestry include a large number from the Pomak and a very small number of Orthodox of ethnic Bulgarian origin. Bulgarian Christians are officially recognized as a minority by the Turkey-Bulgaria Friendship Treaty of 18 October 1925.

Prior to the ethnic cleansing of Thracian Bulgarians in 1913, the Christian Bulgarians had been more than the Pomaks, afterwards Pomak refugees arrived from Greece and Bulgaria. Pomaks are also Muslim and speak a Bulgarian dialect. According to Ethnologue at present 300,000 Pomaks in European Turkey speak Bulgarian as their mother tongue.It is very hard to estimate the number of Pomaks along with the Turkified Pomaks who live in Turkey, as they have blended into the Turkish society and have been often linguistically and culturally assimilated. According to Milliyet and Turkish Daily News reports, the number of the Pomaks is 600,000. The origin of the Pomaks has been debated, but there is an academic consensus that they are descendants of native Bulgarians who converted to Islam during the Ottoman rule of the Balkans.

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; 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.

Inhabited since Paleolithic times, it has been under the political, cultural and linguistic influence of the Greek world since the classical era; Greeks from the Aegean islands extensively colonized the region (especially the coastal part) and built prosperous cities such as Abdera (home of Democritus, the 5th-century BC philosopher who developed an atomic particle theory, and of Protagoras, a leading sophist) and Sale (near present-day Alexandroupolis). Under the Byzantine Empire, Western Thrace 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.
