Duchy of Troppau in the context of "Duchy of Krnov"

Hans-Adam II (Johannes Adam Ferdinand Alois Josef Maria Marco d'Aviano Pius; born 14 February 1945) is the Prince of Liechtenstein, reigning since 1989. He is the son of Prince Franz Joseph II and his wife, Countess Georgina von Wilczek. He also bears the titles Duke of Troppau and Jägerndorf, and Count of Rietberg. Under his reign, a 2003 constitutional referendum expanded the powers of the Prince of Liechtenstein. In 2004, Hans-Adam transferred day-to-day governmental duties to his eldest son Hereditary Prince Alois as regent, as his father had done to him in 1984 to prepare him for the role of Prince.

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.

The Duchies of Silesia were the more than twenty divisions of the region of Silesia formed between the 12th and 14th centuries by the breakup of the Duchy of Silesia, then part of the Kingdom of Poland. In 1335, the duchies were ceded to the Kingdom of Bohemia under the Treaty of Trentschin. Thereafter until 1742, Silesia was one of the Bohemian crown lands and lay within the Holy Roman Empire. Most of Silesia was annexed by the King of Prussia under the Treaty of Berlin in 1742. Only the Duchy of Teschen, the Duchy of Troppau and the Duchy of Nysa remained under the control of the Bohemian crown and as such were known as the Duchy of Upper and Lower Silesia until 1918.

The Duchy of Teschen (German: Herzogtum Teschen), also Duchy of Cieszyn (Polish: Księstwo Cieszyńskie) or Duchy of Těšín (Czech: Těšínské knížectví), was one of the Duchies of Silesia centered on Cieszyn (Teschen) in Upper Silesia. It was split off the Silesian Duchy of Opole and Racibórz in 1281 during the feudal division of Poland and was ruled by Silesian dukes of the Piast dynasty from 1290 until the line became extinct with the death of Duchess Elizabeth Lucretia in 1653.

The ducal lands initially comprised former Lesser Polish territories east of the Biała River, which in about 1315 again split off as the Polish Duchy of Oświęcim, while the remaining duchy became a fiefdom of the Bohemian kings in 1327 and was incorporated into the Lands of the Bohemian Crown in 1348. While the bulk of Silesia was conquered by the Prussian king Frederick the Great in the Silesian Wars of 1740–1763, Teschen together with the duchies of Troppau (Opava), Krnov and Nysa remained with the Habsburg monarchy and merged into the Austrian Silesia crown land in 1849. The so-called "commander line" of the Habsburg-Lorraine dynasty, a cadet branch descending from Archduke Charles, Duke of Teschen, held the title "Duke of Teschen" until 1918.

Nicholas I (Czech: Mikuláš I. Opavský) (c. 1255 – 25 July 1318) was the natural son of Bohemian king Ottokar II Přemysl and his mistress Agnes of Kuenring. In 1269 he became Duke of Opava (at modern day Opava, Czech Republic) and thereby the progenitor of the Silesian cadet branch of the Přemyslid dynasty that lasted until 1521.

He was legitimated by his father with the consent of Pope Alexander IV and raised at the Prague court. As his half-brother Wenceslaus II was designated to succeed his father on the Bohemian throne, Nicholas in compensation received Troppau, then a part of the Moravian march. He supported his father in the 1278 Battle on the Marchfeld, was captured by Hungarian forces, but regained his duchy from the victorious German king Rudolf of Habsburg. His rule was however challenged by Ottokar's widow Kunigunda of Halych, who had retired to Hradec nad Moravicí.
