Museum, taking most of the important artifacts (52 paintings, 12 carpets, 35 folders of prints and drawings, and works by Leonardo da Vinci, Raphael, and Rembrandt) to Dresden because of her connections with the Royal Saxon Family. These works garnered great interest, with the collection being open to the public two days a week. In 1918, after the war, Hans Posse, Director of the royal collections, was unwilling to return the collection. He was fearful of the unrest in Poland. However, after two years of negotiation, all objects were recovered and transferred to the Family Museum in Kraków in 1920. The signing of the 1921 Treaty of Riga provided for the return of all looted or confiscated objects during tsarism due to the Bolshevik revolution.
