من واعد Božena (Křesinová)؟

Božena (Křesinová) (died after 1052) was the second wife (and probably earlier the mistress) of Duke Oldřich of Bohemia and mother of Bretislaus I of Bohemia.

Oldřich I (Latin: Odalricus, Udalrichus; German: Odalric, Udalrich; c. 989 – 9 November 1034 or 1042), a member of the Přemyslid dynasty, was Duke of Bohemia from 1012 to 1033 and briefly again in 1034. His accession to the Bohemian throne marked the start of a phase of stability after a long period of internal dynastic struggles. Under his rule, the Moravian lands were reconquered from Polish occupation.
