Duchy of Brno

1054 CE – 1200 CE (approx.) · capital Brno

One of the Moravian appanage duchies held by junior Přemyslid princes, centred on Brno, until Moravia was reunited as a margraviate.

Origins

Duke Bretislaus I of Bohemia arranged Moravia as a domain for junior members of the Přemyslid dynasty. After his death in 1055, his sons divided it; Conrad I received the Brno portion, centred on the castle of Brno (Brünn) in southern Moravia, while Olomouc and later Znojmo formed separate appanages.

Rule and society

The princes of Brno owed allegiance to the senior duke in Prague but frequently joined in the dynasty's feuds; Conrad I himself briefly became Duke of Bohemia in 1092. Brno grew as a castle and market centre. Little is known in detail of its administration, which followed the Bohemian castle system.

Decline and legacy

In the late 12th century the Moravian appanages were absorbed. Around 1182 Moravia was declared a margraviate directly subject to the emperor, and by about 1197 Vladislaus Henry united the Moravian lands under his rule. Brno later became the capital of the Margraviate of Moravia.
