Ottokar I of Bohemia

Ottokar I (Czech: Přemysl Otakar I.; c. 1155 – 1230) was Duke of Bohemia periodically beginning in 1192, then acquired the title of King of Bohemia, first in 1198 from Philip of Swabia, later in 1203 from Otto IV of Brunswick and in 1212 (as hereditary) from Frederick II. Ottokar was the first hereditary King of Bohemia; although two previous Bohemian monarchs (Vratislaus and Vladislaus II) had held the title of King, in each case the title was awarded only for the life of the recipient. He was an eminent member of the Přemyslid dynasty.
