Vem daterade Oldřich, Duke 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.

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.
