Princess Ludmila was the wife of the first historically documented ruler of the House of Přemysl, the first Czech dynasty, Prince Bořivoj I. She apparently also reigned in Bohemia for a certain time and became famous for her piety and care for the poor. She was the mother of Prince Vratislav I and raised her grandson Václav, who later became the important patron saint of Bohemia. After being murdered at the instigation of her daughter-in-law Drahomíra, she was venerated as a saint and canonized in 1144. She is thus the first Czech and Slavic saint at all. During her life, the foundations of Christianity in Bohemia were laid, as well as the foundations of the power of the Přemysl family. The life of Saint Ludmila has been recorded in a number of legends from Czech history in the 9th and 10th centuries.
