The Lords of Walsee[a] were a German noble family between the 13th and 15th centuries.
Taking their name from Bad Waldsee in Upper Swabia, they were originally ministerials (unfree knights) in the service of the abbey of Weissenburg and the Staufers.
They frequently held the office of Hauptmann (governor) in Lower Austria and Styria.
[1] During the feudal wars at the end of the 13th century they expanded their possessions in some parts of the Croatian-Hungarian Kingdom.
Ulrich I. von Walsee[2][3][4] became lord of Međimurje in northern Croatia.
