Euphemia of Hungary was a daughter of King Béla I of Hungary and his wife, Richesa (or Adelaide) of Poland (1050s – 11 April 1111).[1] She was the wife of Duke Otto I of Olomouc, the second son the Duke of Bohemia Bretislav I .[2][3]
They were married before 1073.[4]
Some researchers believe that Euphemia was the daughter of Bela's older brother Andrew I of Hungary and his wife Anastasia of Kiev, with the alternative name Adelhaid been proposed, due to minimal sources on her birth. Though the theory supported by most scholars and historians[why?] is that Euphemia was born as a result of a marriage between King Bela I and an unknown Piast Princess.[5]
Together they have four children:[6][7][8]
- Svatopluk, Duke of Bohemia (21 September 1109)
- Otto II the Black (18 February 1126)
- Bretislav
- Boleslava
Their youngest two children disappeared from written records and thus, are assumed to have died at a young age.
