Czech Republic in the context of "AM 50"

Historical regions (or historical areas) are geographical regions which, at some point in history, had a cultural, ethnic, linguistic or political basis, regardless of latter-day borders. There are some historical regions that can be considered as "active", for example: Moravia, which is held by the Czech Republic, is both a recognized part of the country as well as a historical region. They are used as delimitations for studying and analysing social development of period-specific cultures without any reference to contemporary political, economic or social organisations.

Definitions of regions vary, and regions can include macroregions such as Europe, territories of traditional sovereign states or smaller microregional areas. Geographic proximity is generally the required precondition for the emergence of a regional identity. In Europe, regional identities are often derived from the Migration Period but for the contemporary era are also often related to the territorial transformations that followed World War I and those that followed the Cold War.

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.

Moravia is a historical region in the east of the Czech Republic and one of three historical Czech lands, with Bohemia and Czech Silesia.

The medieval and early modern Margraviate of Moravia was a crown land of the Lands of the Bohemian Crown from 1348 to 1918, an imperial state of the Holy Roman Empire from 1004 to 1806, a crown land of the Austrian Empire from 1804 to 1867, and a part of Austria-Hungary from 1867 to 1918. Moravia was one of the five lands of Czechoslovakia founded in 1918. In 1928 it was merged with Czech Silesia, and then dissolved in 1948 during the abolition of the land system following the communist coup d'état.

Germany, officially the Federal Republic of Germany, is a country in Western and Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen constituent states have a total population of over 83 million, making it the most populous member state of the European Union. Germany borders Denmark to the north; Poland and the Czech Republic to the east; Austria and Switzerland to the south; and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr.

Settlement in the territory of modern Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts, with Germanic tribes inhabiting the north. Romans named the area Germania. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation. Following the Napoleonic Wars and the dissolution of the Holy Roman Empire in 1806, the German Confederation was formed in 1815.

Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps. It is a federation of nine states, of which the capital Vienna is the most populous city and state. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of 83,879 km (32,386 sq mi) and has a population of around 9 million.

The area of today's Austria has been inhabited since at least the Paleolithic period. Around 400 BC, it was inhabited by the Celts and then annexed by the Romans in the late 1st century BC. Christianization in the region began in the 4th and 5th centuries, during the late Roman period, followed by the arrival of numerous Germanic tribes during the Migration Period.

In the Czech Republic, 47.8% of the population is irreligious (atheist, agnostic or other irreligious life stances), while 21.3% of the population are believers. The religious identity of the country has changed drastically since the first half of the 20th century, when more than 90% of Czechs were Christians. As of 2021, 11.7% of the population identified with Christianity (9.3% identifying with Catholicism and 2.4% with all other Christian denominations); 10.8% identified with other religious identities or beliefs. According to sociologist Jan Spousta, not all the irreligious people are atheists; indeed, since the late 20th century there has been an increasing distancing from both Christian dogmatism and atheism, and at the same time ideas and non-institutional models similar to those of Eastern religions have become widespread through movements started by various gurus, and hermetic and mystical paths.

Slovakia, officially the Slovak Republic, is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the west, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about 49,000 km (19,000 sq mi), hosting a population exceeding 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice.

The Slavs arrived in the territory of the present-day Slovakia in the 5th and 6th centuries. From the late 6th century, parts of modern Slovakia were incorporated into the Avar Khaghanate. In the 7th century, the Slavs played a significant role in the creation of Samo's Empire. When the Avar Khaghanate dissolved in the 9th century, the Slavs established the Principality of Nitra before it was annexed by the Principality of Moravia, which later became Great Moravia. When Great Moravia fell in the 10th century, the territory was integrated into the Principality of Hungary at the end of the 9th century, which later became the Kingdom of Hungary in 1000. In 1241 and 1242, after the Mongol invasion of Europe, much of the territory was destroyed, but was recovered largely thanks to Hungarian king Béla IV. During the 16th and 17th centuries, southern portions of present-day Slovakia were incorporated into provinces of the Ottoman Empire. The Ottoman-controlled areas were ceded to the Habsburgs by the turn of the 18th century. The Hungarian declaration of independence in 1848 was followed in the same year by the Slovak Uprising through the establishment of the Slovak National Council. While the uprising did not achieve its aim, it played an important role in cementing a Slovak national identity. The Hungarian wars of independence eventually resulted in a compromise that established the Austro-Hungarian Empire.

Poland, officially the Republic of Poland, is a country in Central Europe. It extends from the Baltic Sea in the north to the Sudetes and Carpathian Mountains in the south, and borders Lithuania and Russia to the northeast; Belarus and Ukraine to the east; Slovakia and the Czech Republic to the south; and Germany to the west. The territory has a varied landscape, diverse ecosystems, and a temperate climate. Poland is composed of sixteen voivodeships and is the fifth most populous member state of the European Union (EU), with over 38 million people, and the fifth largest EU country by land area, covering 312,696 km (120,733 sq mi). The capital and largest city is Warsaw; other major cities include Kraków, Wrocław, Łódź, Poznań, and Gdańsk.

Prehistoric human activity on Polish soil dates to the Lower Paleolithic, with continuous settlement since the end of the Last Glacial Period. Culturally diverse throughout late antiquity, in the early medieval period the region became inhabited by the West Slavic tribal Polans, who gave Poland its name. The process of establishing statehood coincided with the conversion of a pagan ruler of the Polans to Christianity in 966. Under the auspices of the Roman Catholic Church, the dominion became part of the Western world. In 1025, the Kingdom of Poland emerged, and in 1569 it cemented its long-standing association with Lithuania, forming the Polish–Lithuanian Commonwealth. At the time, the Commonwealth was one of Europe's great powers, with an elective monarchy and a uniquely liberal political system. It adopted Europe's first modern constitution in 1791.

Central Europe is a geographical region of Europe between Eastern, Southern, Western and Northern Europe. Central Europe is known for its cultural diversity; however, countries in this region also share certain historical and cultural similarities.

The region is variously defined but often includes Austria, Croatia, the Czech Republic, Germany, Hungary, Liechtenstein, Lithuania, Poland, Slovakia, Slovenia and Switzerland. Throughout much of the Early Modern period, the territories of Poland and Lithuania were part of the Polish–Lithuanian Commonwealth. Meanwhile, the Ottoman Empire came to occupy most of present-day Croatia and present-day Hungary, and southern parts of present-day Slovakia. The Archduchy of Austria, the Kingdom of Bohemia (Czech Republic), the Duchy of Carniola (part of present-day Slovenia), the various German Principalities and the Old Swiss Confederacy were within the Holy Roman Empire. During the 18th century, the Habsburg monarchy came to reign over the territories of Austria, Croatia, the Czech Republic, Hungary, Slovakia and Slovenia, alongside parts of Serbia, Germany, Italy and Switzerland. Bosnia and Herzegovina, however, was not under Habsburg control during the 18th century; it was occupied in 1878 following the Congress of Berlin and formally annexed in 1908. Between the early 18th and the early 20th centuries, Central Europe had a substantial Jewish population.
