A report on Ottokar II of Bohemia and Přemyslid dynasty

The kingdom was established by the Přemyslid dynasty in the 12th century from the Duchy of Bohemia, later ruled by the House of Luxembourg, the Jagiellonian dynasty, and from 1526 the House of Habsburg and its successor, the House of Habsburg-Lorraine.

Přemysl Ottokar II (1253–78) married a German princess, Margaret of Babenberg, and became duke of Austria.

He was the only son of King Ottokar II of Bohemia and Ottokar's second wife Kunigunda.

He was a member of the Přemyslid dynasty.

Originally a Swabian count, he was the first Habsburg to acquire the duchies of Austria and Styria in opposition to his mighty rival, the Přemyslid king Ottokar II of Bohemia, whom he defeated in the 1278 Battle on the Marchfeld.

The opponents were a Bohemian (Czech) army led by the Přemyslid king Ottokar II of Bohemia and the German army under the German king Rudolph I of Habsburg in alliance with King Ladislaus IV of Hungary.

Temporarily ruled by King Bolesław I Chrobry of Poland from 999 until 1019, Moravia was re-conquered by Duke Oldřich of Bohemia and ultimately became a land of the Crown of Saint Wenceslas held by the Přemyslid dynasty.

As heir apparent, the future King Ottokar II of Bohemia was appointed Moravian margave by his father Wenceslaus I in 1247.

A native monarchy arose to the throne, and Bohemia came under the rule of the Přemyslid dynasty, which would rule the Czech lands for the next several hundred years.

His grandson Ottokar II (king from 1253 to 1278) conquered a short-lived empire that contained modern Austria and Slovenia.

The Principality of Opava (Opavské knížectví; Księstwo Opawskie) or Duchy of Troppau (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.

Ottokar II of Bohemia (c. 1230 – 26 August 1278)

Wenceslaus' foreign policy became focused on acquiring Austria for the Přemyslid dynasty.

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.
