In 1847 Liszt met Princess Carolyne zu Sayn-Wittgenstein, the estranged wife of a German prince who lived in Russia. By the autumn of 1848 she and Liszt had become lovers, and their relationship lasted for the remainder of his life. She quickly assumed responsibility for the management of Liszt's life, including the upbringing of his daughters. Early in 1850 Liszt had been disturbed to learn that Blandine and Cosima were seeing their mother again; his response, guided by the princess, was to remove them from their school and place them into the full-time care of Carolyne's old governess, the 72-year-old Madame Patersi de Fossombroni. Liszt's instructions were clear—Madame Patersi was to control every aspect of the girls' lives: "She alone is to decide what is to be permitted them and what forbidden".
