Central Europe in the context of "Romania"

The Ottoman Empire, also known as the Turkish Empire, controlled much of Southeast Europe, West Asia, and North Africa from the 14th century to the early 20th century. It also controlled parts of southeastern Central Europe between the early 16th and early 18th centuries.

The empire emerged from a beylik, or principality, founded in northwestern Anatolia in c. 1299 by the Turkoman tribal leader Osman I. His successors conquered much of Anatolia and expanded into the Balkans by the mid-14th century, transforming their petty kingdom into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Mehmed II. With its capital at Constantinople and control over a significant portion of the Mediterranean Basin, the Ottoman Empire was at the centre of interactions between the Middle East and Europe for six centuries. Ruling over so many peoples, the empire granted varying levels of autonomy to its many confessional communities, or millets, to manage their own affairs per Islamic law. During the reigns of Selim I and Suleiman the Magnificent in the 16th century, the Ottoman Empire became a global power.

Serbia, officially the Republic of Serbia, is a landlocked country in Southeast and Central Europe. Located in the Balkans, it borders Hungary to the north, Romania to the northeast, Bulgaria to the southeast, North Macedonia to the south, Croatia to the northwest, Bosnia and Herzegovina to the west, and Montenegro to the southwest. Serbia also claims to share a border with Albania through the disputed territory of Kosovo. Serbia has about 6.6 million inhabitants, excluding Kosovo. Serbia's capital, Belgrade, is also the largest city in the country.

Continuously inhabited since the Paleolithic age, the territory of modern-day Serbia faced Slavic migrations in the 6th century. Several regional states were founded in the Early Middle Ages and were at times recognised as tributaries to the Byzantine, Frankish and Hungarian kingdoms. The Serbian Kingdom obtained recognition by the Holy See and Constantinople in 1217, reaching its territorial apex in 1346 as the Serbian Empire. By the mid-16th century, the Ottoman Empire annexed the entirety of modern-day Serbia; their rule was at times interrupted by the Habsburg Empire, which began expanding towards Central Serbia from the end of the 17th century while maintaining a foothold in Vojvodina. In the early 19th century, the Serbian Revolution established the nation-state as the region's first constitutional monarchy, which subsequently expanded its territory.

The early Slavs were an Indo-European peoples and speakers of the Indo-European dialectswho lived during the Migration Period and the Early Middle Ages (approximately from the 5th to the 10th centuries AD) in Central, Eastern and Southeast Europe and established the foundations for the Slavic nations through the Slavic states of the Early and High Middle Ages. The Slavs' original homeland is still a matter of debate due to a lack of historical records; however, scholars generally place it in Eastern Europe, with Polesia being the most commonly accepted location.

It is generally agreed that ancient Roman writers referred to the ancestors of Slavs as Venedi. The proto-Slavic term Slav shares roots with Slavic terms for speech, word, and perhaps was used by early Slavic people themselves to denote other people, who spoke languages similar to theirs. The first written use of the name "Slavs" dates to the 6th century, when the Slavic tribes inhabited a large portion of Central and Eastern Europe. By then, the nomadic Iranian-speaking peoples living in the European Pontic Steppe (the Scythians, Sarmatians, Alans, etc.) had been absorbed by the region's Slavic-speaking population. Over the next two centuries, the Slavs expanded westwards (to the Elbe river and in the Alps), and southwards (into the Balkans, absorbing Illyrian and Thracian peoples in the process), and also moved eastwards (in the direction of the Volga River). Between the sixth and seventh centuries, large parts of Europe came to be controlled or occupied by Slavs, a process less understood and documented than that of the Germanic ethnogenesis in the west. Yet the effects of Slavicization were far more profound.

The Slavs or Slavic people are a major ethnic group in Europe. They speak Slavic languages and preserve Slavic culture. There are 13 Slavic countries in Europe, which include: Poland, the Czech Republic, Slovakia, Russia, Belarus, Ukraine, Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, North Macedonia, and Bulgaria; the Slavs comprise a population of around 300 million people. There are three different Slavic ethnic groups: the West Slavs, the East Slavs, and the South Slavs; the Poles, Silesians, Kashubians, Sorbs, Czechs, and Slovaks are West Slavs; Russians, Belarusians, Ukrainians, and Rusyns are East Slavs; while Slovenes, Resians, Croats, Bosniaks, Serbs, Montenegrins, Torlakians, the Gorani, the Torbeši, Macedonians, and Bulgarians are South Slavs. Slavs are geographically distributed throughout the northern parts of Eurasia; they predominantly inhabit Central Europe, Eastern Europe, Southeastern Europe, and Northern Asia, though there is a large Slavic minority scattered across the Baltic states and Central Asia, and a substantial Slavic diaspora in the Americas, Western Europe, and Northern Europe.

Early Slavs lived during the Migration Period and the Early Middle Ages (approximately from the 5th to the 10th century AD), and came to control large parts of Central, Eastern, and Southeast Europe between the sixth and seventh centuries. Beginning in the 7th century, they were gradually Christianized. By the 12th century, they formed the core population of a number of medieval Christian states: East Slavs in the Kievan Rus', South Slavs in the Bulgarian Empire, the Principality of Serbia, the Duchy of Croatia and the Banate of Bosnia, and West Slavs in the Principality of Nitra, Great Moravia, the Duchy of Bohemia, and the Kingdom of Poland.

Eastern Europe is a subregion of the European continent. As a largely ambiguous term, it has a wide range of geopolitical, geographical, ethnic, cultural and socio-economic connotations. Its eastern boundary is marked by the Ural Mountains, and its western boundary is defined in various ways. Narrow definitions, in which Central and Southeast Europe are counted as separate regions, include Belarus, Russia and Ukraine. In contrast, broader definitions include Moldova and Romania, but also some or all of the Balkans, the Baltic states, the Caucasus, and the Visegrád group. In Eastern Europe, Russia is the largest and most populous country.

The region represents a significant part of European culture; the main socio-cultural characteristics of Eastern Europe have historically largely been defined by the traditions of the Slavs, as well as by the influence of Eastern Christianity as it developed through the Eastern Roman Empire and the Ottoman Empire. Another definition was created by the Cold War, as Europe was ideologically divided by the Iron Curtain, with "Eastern Europe" being synonymous with communist states constituting the Eastern Bloc under the influence of the Soviet Union.

The Czech Republic, also known as Czechia and historically known as Bohemia, is a landlocked country in Central Europe. The country is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of 78,871 square kilometers (30,452 sq mi) with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec.

The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial Estate of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, all of the Lands of the Bohemian Crown were gradually integrated into the Habsburg monarchy. Nearly a hundred years later, the Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Roman Empire in 1806, the Crown lands became part of the Austrian Empire.

The revolutions of 1989, also known as the fall of communism, were a wave of liberal democratic movements that resulted in the collapse of most Marxist–Leninist governments in the Eastern Bloc and other parts of the world. This wave is sometimes referred to as the "autumn of nations", in reference to the revolutions of 1848 as the "spring of nations". The revolutions of 1989 were a key factor in the dissolution of the Soviet Union—one of the two superpowers—and abandonment of communist regimes in many parts of the world, some of which were violently overthrown. These events drastically altered the world's balance of power, marking the end of the Cold War and beginning of the post-Cold War era.

The earliest recorded protests, which led to the revolutions, began in Poland on 14 August 1980, the massive general strike which led to the August Agreements and establishment of Solidarity, the first and only independent trade union in the Eastern Bloc, whose peak membership reached 10 million. The main region of the 1989 revolutions was Central Europe, starting in Poland with the 1988 Polish strikes, and continued in Hungary, East Germany, Bulgaria, Czechoslovakia, and Romania. On 4 June 1989, Poland conducted the first elections that led to the dissolution of the communist government, with Solidarity winning an overwhelming victory, leading to the peaceful fall of communism in Poland. Influenced by Poland, Hungary organised round table-format talks and began dismantling its section of the Iron Curtain. In August 1989, over a quarter of the Baltic states population physically chained for 675 kilometres (419 mi) in the Baltic Way protesting the occupation by the Soviet Union, while the opening of a border gate between Austria and Hungary set in motion a peaceful chain reaction, in which the Eastern Bloc disintegrated. This led to mass demonstrations in cities of East Germany and the fall of the Berlin Wall in November 1989, which served as the symbolic gateway to German reunification in 1990. A feature common to these developments was the extensive use of campaigns of civil resistance, demonstrating popular opposition to the continuation of one-party rule and contributing to pressure for change. Romania was the only country in which citizens and opposition forces used violence to overthrow its communist regime, although Romania was politically isolated from the rest of the Eastern Bloc.

Switzerland, officially the Swiss Confederation, is a landlocked country located at the intersection of Central, Western, and Southern Europe. It is bordered by Germany to the north, France to the west, Austria and Liechtenstein to the east, and Italy to the south. Switzerland is geographically divided among the Swiss Alps, the Swiss Plateau, and the Jura mountains; the Alps cover most of the country's territory, whereas the majority of its 9 million people are concentrated on the plateau, which hosts many of the largest cities and economic centres, including Zurich, Geneva, Basel, Bern, Lausanne, Winterthur, and Lucerne.

Switzerland is a federal republic composed of 26 cantons, with Bern serving as the federal city and the seat of the national government. The country encompasses four principal linguistic and cultural regions—German, French, Italian, and Romansh—reflecting a long-standing tradition of multilingualism and cultural pluralism. Swiss national identity nonetheless remains fairly cohesive, rooted in a shared historical background, common values such as federalism and direct democracy, and Alpine symbolism. Swiss nationhood transcends language, ethnicity, and religion, leading to Switzerland being described as a Willensnation ("nation of volition") rather than a conventional nation state.

The Iron Age (c. 1200 – c. 550 BC) is the final epoch of the three historical Metal Ages, after the Copper Age and Bronze Age. It has also been considered as the final age of the three-age division starting with prehistory (before recorded history) and progressing to protohistory (before written history). In this usage, it is preceded by the Stone Age (subdivided into the Paleolithic, Mesolithic and Neolithic) and Bronze Age. These concepts originated for describing Iron Age Europe and the ancient Near East. In the archaeology of the Americas, a five-period system is conventionally used instead; indigenous cultures there did not develop an iron economy in the pre-Columbian era, though some did work copper and silver. Indigenous metalworking arrived in Australia with European contact. Although meteoric iron has been used for millennia in many regions, the beginning of the Iron Age is defined locally around the world by archaeological convention when the production of smelted iron (especially steel tools and weapons) replaces their bronze equivalents in common use.

In Anatolia and the Caucasus, or Southeast Europe, the Iron Age began c. 1300 BC. In the ancient Near East, this transition occurred simultaneously with the Late Bronze Age collapse, during the 12th century BC. The technology soon spread throughout the Mediterranean basin region and to South Asia between the 12th and 11th centuries BC. Its further spread to Central Asia, Eastern Europe, and Central Europe was somewhat delayed, and Northern Europe was not reached until c. the 5th century BC.
