4 Stivers / Arendschelling - Anne van de Marck with titles of Matthias II

The Abbey of Thorn was a remarkably autonomous institution — a secular canoness chapter whose abbesses held the rank of imperial princess and exercised direct territorial authority over the surrounding lordship. Anne van de Marck, who held the abbacy from 1611 to 1619, issued coins under the titles of Emperor Matthias II as a formal acknowledgment of imperial suzerainty, a requirement for any Reichsunmittelbar house exercising the right of coinage. The arrangement was largely ceremonial; Thorn's monetary independence was its own.
