Drahomíra was born in the present-day Havelland region centered around the fortress of Brandenburg, the daughter of a Hevelli prince. According to Cosmas of Prague, she married Duke Vratislav I of Bohemia about 906. Drahomíra gave birth to at least six children: her sons were Wenceslaus and Boleslaus, who both succeeded their father as Bohemian dukes. Among her four daughters was one Přibislava, whose considered to have married to a Croatian prince, who became a nun at the Prague St. George's Convent, and possibly Střezislava, the wife of the Bohemian nobleman Slavník, founder of the Slavník dynasty. The marriage led the Přemyslid dynasty to cooperation with the Polabian Slavs and brought Bohemia in conflict with the Saxon duke Henry the Fowler, who became German king in 919 and later waged war against the Hevelli tribes. After her husband's untimely death in 921, the Bohemian nobles designated Drahomíra regent for her minor son Wenceslaus. However, she had to divide the government of Bohemia with her mother-in-law Ludmila, widow of Duke Bořivoj I, who took over the religious education of her sons. Popular history depicts Ludmila as a restrained and pious grandmother, but it is likely that the political demands of government called for more energy and worldliness than history records. Wenceslaus was one of the main reasons for the eventually fatal discord between Drahomíra and Ludmila, who had exerted great influence over Drahomíra's eldest son, leaving Drahomíra to concentrate her efforts on her younger son, Boleslaus. Despite or perhaps as a result of her political and personal efforts, Ludmila attracted Drahomíra's bitter enmity. She alleged that her mother-in-law, with the help of Bavarian missionaries, educated Wenceslaus to become a monk rather than a prince. Moreover, the two women may have disagreed whether to recognise the East Frankish supremacy of Henry the Fowler. Ludmila fled from Prague to Tetín Castle on the road to Regensburg, where on 16 September 921 Drahomíra's henchmen, Tunna and Gommon, attacked and strangled her. The next year the troops of Duke Arnulf of Bavaria raided the Bohemian duchy. When Drahomíra's son Wenceslaus came of age about 922, he sent his mother into exile, though he called her back in 925. She spent her later years in Prague, however, upon the murder of her son she fled from the court to the Croats. While some considered that the Croats lived near Prague, others noted that in the case of noble and royal fugitives tried to find security as distant as possible, indicating these Croats probably were located more to the East around Vistula valley.
