The Ukrainian People's Republic was founded in 1918 and stood in opposition to the Bolshevik USSR. After the conquest by the USSR in 1920, the Ukrainian Soviet Socialist Republic was established.
The Soviet Union (SU or USSR) was a state in Eastern Europe, Central and Northern Asia that existed from 1922 to 1991. It emerged from the so-called Soviet Russia, the successor state of the Russian Empire. The Russian Soviet Republic formed the core of the union and at the same time its largest part, with further constituent republics added. Their number varied over time and was related to the occupation of other countries (Estonia, Latvia, Lithuania), Soviet republics that existed only for a short time (Karelo-Finlandia) or the division or merger of Soviet republics. In addition, there were numerous autonomous republics or other territorial units with an autonomy status that was essentially limited to linguistic autonomy for minorities.
Before its formal dissolution, the USSR consisted of 15 Soviet republics with a population of approximately 290 million people. At around 22.4 million km², it was the largest territorial state in the world at the time. The Soviet Union was a socialist soviet republic with a one-party system and an absence of separation of powers.
Galicia is a historical landscape, which today is almost entirely located on the territory of Poland and Ukraine. The part in southeastern Poland is usually referred to as Western Galicia, and the part in western Ukraine as Eastern Galicia. Before 1772, Galicia belonged for centuries to the Polish-Lithuanian noble republic, and subsequently and until 1918 - as part of the crown land "Kingdom of Galicia and Lodomeria" - to the Habsburg Empire.
Austria-Hungary (Hungarian: Osztrák-Magyar Monarchia), also known as Imperial and Royal Hungary Monarchy, was a historical state in Central and Southeastern Europe that existed from 1867 to 1918.
The Second Polish Republic (Polish: II. Rzeczpospolita) is the common name for the Polish state (Republic of Poland) after it regained independence on 11.11.1918 in connection with the end of the First World War, following 123 years of partition. The territorial extent of the Second Polish Republic, especially to the east, was considerably smaller than that of the so-called 1st Republic (Republic of Nobles), which ceased to exist in 1795 with the third partition of Poland between the Habsburg Monarchy, Prussia and Russia.
The borders of the Second Polish Republic with the neighboring states were not established until 1921/22 and as a result of armed conflicts, although they remained controversial even afterwards (and in some cases for the entire existence of the Second Polish Republic). The German aggression on Poland on September 1, 1939 and the Soviet invasion of Poland on September 17, 1939 were followed by the capitulation in Warsaw on September 28, 1939, which was the functional end of the Second Republic. The withdrawal of recognition of the Polish government-in-exile by the British and US governments on 5 July 1945 is often regarded as its formal end, although the organs of the later People's Republic of Poland were already recognized by the Soviet Union as the official representation of Poland on 24 June 1944. The President of the Polish government-in-exile in London, Ryszard Kaczorowski, handed over the insignia of the Second Republic to the then President in Warsaw, Lech Wałęsa, on 22.12.1990 as the last symbolic act of the Second Polish Republic.
Czechoslovakia was a state existing between 1918 and 1992 with changing borders, names, and political systems. Its territories are now part of the modern-day states of Czechia, Slovakia, and Ukraine (Carpathian Ukraine, occupied by Hungary in 1939 and transferred to the Soviet Union in 1945). After 1945, Czechoslovakia came under increasing political influence from the Soviet Union. After the communist party seized power in 1948, the country finally became part of the so-called Eastern Bloc, a satellite state of the Soviet Union, and a member of the Warsaw Pact from 1955. Between 1960 and 1990, the communist country was officially known as the Czechoslovak Socialist Republic (abbreviated to ČSSR). The democratic political change was initiated in 1989 with the Velvet Revolution and culminated in 1992 with the founding of the independent Czech and Slovak Republics.
A place to exercise knowledge and power
Prague (population 2024: 1,397,880) is the capital and largest city of the Czech Republic. It is located in the center of the urban area on the Vltava River. The first Prague Castle was probably built in the 9th century. In the 10th/11th century, immigrant Jews lived alongside the local population in what were initially two neighboring castle settlements. At the beginning of the 1230s, Prague was granted city rights, followed by Malá Strana in 1257, Hradčany as a castle town in 1320 and the New Town of Prague (Nové Město) in 1348. From the very beginning, Prague was the residence of the Bohemian rulers, at the latest from the 12th century within the borders of the Holy Roman Empire. As the seat of the emperor in the 14th century, Prague developed into one of the most important centers of the entire empire, and the first university in Central Europe was founded here in 1348. In 1784, the four cities were formally united. Gradually, especially in 1920 and after the founding of Czechoslovakia in 1918, further towns were incorporated. Between 1938 and 1945, Prague became the capital of the Protectorate of Bohemia and Moravia, which was dependent on the German Reich. After the Allies broke up the Reich in 1945, Prague was once again the capital of - now socialist - Czechoslovakia until 1992. After the collapse of Czechoslovakia, Prague remained the capital of the Czech Republic and one of the most culturally, economically and politically important cities in Central Europe.
From treasure trove of knowledge to spoils of war
Academic doppelgangers and ideological control
Wrocław (German: Breslau) is one of the largest cities in Poland (population in 2022: 674,079). It is located in the Lower Silesian Voivodeship in the southwest of the country.
Initially under Bohemian, Piast and at other times Hungarian rule, the Habsburgs took over the Silesian territories in 1526, including Wrocław. Another turning point in the city's history was the occupation of Wroclaw by Prussian troops in 1741 and the subsequent incorporation of a large part of Silesia into the Kingdom of Prussia.
The dramatic increase in population and the fast-growing industrialization led to the rapid urbanization of the suburbs and their incorporation, which was accompanied by the demolition of the city walls at the beginning of the 19th century. By 1840, Breslau had already grown into a large city with 100,000 inhabitants. At the end of the 19th century, the cityscape, which was often still influenced by the Middle Ages, changed into a large city in the Wilhelmine style. The highlight of the city's development before the First World War was the construction of the Exhibition Park as the new center of Wrocław's commercial future with the Centennial Hall from 1913, which has been a UNESCO World Heritage Site since 2006.
In the 1920s and 30s, 36 villages were incorporated and housing estates were built on the outskirts of the city. In order to meet the great housing shortage after the First World War, housing cooperatives were also commissioned to build housing estates.
Declared a fortress in 1944, Wrocław was almost completely destroyed during the subsequent fightings in the first half of 1945. Reconstruction of the now Polish city lasted until the 1960s.
Of the Jewish population of around 20,000, only 160 people found their way back to the city after the Second World War. Between 1945 and 1947, most of the city's remaining or returning - German - population was forced to emigrate and was replaced by people from the territory of the pre-war Polish state, including the territories lost to the Soviet Union.
After the political upheaval of 1989, Wrocław rose to new, impressive heights. The transformation process and its spatial consequences led to a rapid upswing in the city, supported by Poland's accession to the European Union in 2004. Today, Wrocław is one of the most prosperous cities in Poland.
