of Bavaria-Munich In Innsbruck Kunigunde met Duke George's cousin, Albert IV, then ruler of Bavaria-Munich and about 18 years her senior, who she married on 2 January 1487. Her father had initially given his consent, however, when Albert's forces occupied the Imperial City of Regensburg, he changed his mind. The couple wed at the Innsbruck Hofburg residence, against the will of Kunigunde's father. Her brother Maximilian mediated between her and Emperor Frederick; he was able to prevent an imperial ban. Kunigunde followed her husband to Bavaria and served as joint regent for their eldest son William IV, born in 1493. In spite of her resignation from the Imperial court, she tried to influence the politics of the state as she acted in favour of the rights of her younger sons. She stayed in close contact with her brother, Emperor Maximilian I, and with other rulers and relatives in Europe. After the death of Albert in 1508 she later joined the Convent of Püttrich which she favoured and lived there until her death in 1520. Dowager Duchess She was very pious and able to exert influence in her brother on religious matters. In 1509, relying on the influence of Kunigunde, and the Cologne Dominicans, the anti-Jewish agitator Johannes Pfefferkorn was authorized by Maximilian to confiscate all offending Jewish books (including prayer books), except the Bible. The confiscations happened in Frankfurt, Bingen, Mainz and other German cities. Responding to the order, the archbishop of Mainz, the city council of Frankfurt and various German princes tried to intervene in defense the Jews. Maximilian consequently ordered the confiscated books to be returned. On May 23, 1510 though, influenced by a supposed "host desecration" and blood libel in Brandenburg, as well as pressure from Kunigunde, he ordered the creation of an investigating commission and asked for expert opinions from German universities and scholars. The prominent humanist Johann Reuchlin argued strongly in defense of the Jewish books, especially the Talmud. In 1512, Kunigunde exposed the fraud of the self-appointed saint Anna Laminit (1480-1518) of Augsburg, who had duped the population and enriched herself using her fame as a "hunger saint" for decades. Laminit had managed to approach even Maximilian himself, who paid personal visits to her and provided her and her maid with clothing. In 1503, Laminit attained her greatest success in persuading Bianca Maria Sforza, her brother's Queen (later Empress), to lead a penitent procession
