Conrad II of Bohemia
Konrád Ota II (died 9 September 1191) was a member of Přemyslid dynasty, son of Duke Conrad II of Znojmo. Originally the ruler of Moravia-Znojmo (Mähren-Znojmo) Konrád Ota unified Moravia under his rule in the 1170s by conquering Brno (Brünn) in 1176 and then Olomouc (Olmütz) in 1179. When Frederick of Bohemia|Bedřich]] (Frederick), the son of Vladislav II, ruler of Bohemia, was expelled from Bohemia by his barons, Konrád Ota tried to take control of Bohemia too. The Emperor Frederick Barbarossa, to whom Bedřich had fled, summoned both Přemyslids to appear before his tribunal at Ratisbon, and decided on September 29, 1182 to keep Bedřich as the ruler of Bohemia, but compensated Konrád Ota with the margraviate of Moravia, independent of Bohemia.
With the death of the Bedřich he became the ruler of Bohemia too, but was forced to allow important concessions to his baron supporters.
