Duchies of Silesia in the context of "Bohemian Crown"

The Lands of the Bohemian Crown were the states in Central Europe during the medieval and early modern periods with feudal obligations to the Bohemian kings. The crown lands primarily consisted of the Kingdom of Bohemia, an electorate of the Holy Roman Empire according to the Golden Bull of 1356, the Margraviate of Moravia, the duchies of Silesia, and the two Lusatias, known as the Margraviate of Upper Lusatia and the Margraviate of Lower Lusatia, as well as other territories throughout its history. This agglomeration of states nominally under the rule of the Bohemian kings was referred to simply as Bohemia.

The joint rule of Corona regni Bohemiae was legally established by decree of King Charles IV issued on 7 April 1348, on the foundation of the original Czech lands ruled by the Přemyslid dynasty until 1306. By linking the territories, the interconnection of crown lands thus no more belonged to a king or a dynasty but to the Bohemian monarchy itself, symbolized by the Crown of Saint Wenceslas. During the reign of King Ferdinand I from 1526, the lands of the Bohemian Crown became a constituent part of the Habsburg monarchy. A large part of Silesia was lost in the mid-18th century, but the rest of the Lands passed to the Austrian Empire and the Cisleithanian half of Austria-Hungary. By the Czechoslovak declaration of independence in 1918, the remaining Czech lands became part of the First Czechoslovak Republic.

The House of Piast was the first historical ruling dynasty of Poland. The first documented Polish monarch was Duke Mieszko I (c. 960–992). The Piasts' royal rule in Poland ended in 1370 with the death of King Casimir III the Great.

Branches of the Piast dynasty continued to rule in the Duchy of Masovia (until 1526) and in the Duchies of Silesia until the last male Silesian Piast died in 1675. The Piasts intermarried with several noble lines of Europe, and possessed numerous titles, some within the Holy Roman Empire. The Jagiellonian kings ruling after the death of Casimir IV of Poland were also descended in the female line from Casimir III's daughter.

Although the Kingdom of Bohemia, both of the Lusatias, the Margraviate of Moravia, and Silesia were all under Habsburg rule, they followed different paths of development. Moravians and Silesians had accepted the hereditary right of the Austrian Habsburgs to rule and thus escaped the intense struggle between native estates and the Habsburg monarchy that was to characterize Bohemian history. In contrast, the Bohemian Kingdom had entrenched estates that were ready to defend what they considered their rights and liberties. The Habsburgs pursued a policy of centralization and conflict arose, which was further complicated by ethnic and religious issues.

The House of Hunyadi was one of the most powerful noble families in the Kingdom of Hungary during the 15th century. A member of the family, Matthias Corvinus, was King of Hungary from 1458 until 1490, King of Bohemia (ruling in Moravia, Lower Lusatia, Upper Lusatia, and Silesia) from 1469 until 1490, and Duke of Austria from 1487 until 1490. His illegitimate son, John Corvinus, ruled the Duchy of Troppau from 1485 until 1501, and five further Silesian duchies, including Bytom, Głubczyce, Loslau, Racibórz, and Tost, from 1485 until 1490. The Hunyadi coat-of-arms depicted a raven with a golden ring in its beak.

The founder of the family, Voyk, received the eponymous Hunyad Castle (in present-day Hunedoara, Romania) from Sigismund, King of Hungary, in 1409. His ethnicity is the subject of scholarly debate. Some modern historians describe him as a Vlach, or Romanian, knez or boyar, from either Wallachia or Transylvania. Others describe him as a Cuman or Slav nobleman. According to the 15th-century historian, Johannes de Thurocz, Voyk moved from Wallachia to Transylvania. Voyk's oldest son, John Hunyadi, was often mentioned as a "Vlach" by his contemporaries.

Czech Baroque architecture refers to the architectural period of the 17th and 18th century in Bohemia, Moravia and Silesia, which comprised the Crown of Bohemia and today constitute the Czech Republic.

The Baroque style also changed the character of the Czech countryside (churches and chapels in Czech countryside are mostly Baroque). Czech Baroque architecture is considered to be a unique part of the European cultural heritage thanks to its extensiveness and extraordinariness. In the first third of the 18th century the Czech lands (especially Bohemia) were one of the leading artistic centers of the Baroque style. In Bohemia there was completed in a very original way the development of the Radical Baroque style created in Italy by Francesco Borromini and Guarino Guarini. The leading architects of the Czech High Baroque style (also called Radical Baroque of Bohemia) were Christoph Dientzenhofer, Kilian Ignaz Dientzenhofer and Jan Blažej Santini-Aichel.

The Principality of Opava (Czech: Opavské knížectví; Polish: Księstwo Opawskie) or Duchy of Troppau (German: Herzogtum Troppau) was a historic territory split off from the Margraviate of Moravia before 1269 by King Ottokar II of Bohemia to provide for his natural son, Nicholas I. The Opava territory thus had not been part of the original Polish Duchy of Silesia in 1138, and was first ruled by an illegitimate offshoot of the Bohemian Přemyslid dynasty, not by the Silesian Piasts like many of the neighbouring Silesian duchies. Its capital was Opava (Troppau) in the modern-day Czech Republic.

From 1337 onwards, the Přemyslid dukes also ruled the adjacent former Piast Duchy of Racibórz, whereupon Opava became united with the Upper Silesian lands. When the Opava branch became extinct in 1464, it fell back to the Bohemian Crown, from 1526 part of the Habsburg monarchy. In the final three centuries of its existence, the duchy was ruled by the House of Liechtenstein. It was dissolved with the Austro-Hungarian Empire in 1918, but the title of Duke of Troppau and Jägerndorf still exists, belonging to a present-day monarch, Prince Hans-Adam II of Liechtenstein. The Duchy of Jägerndorf (Krnov) was another of the Silesian duchies.
