Jørgen Kaas

Jørgen Kaas (1618 – 30 January 1658 in Fyn) was a Danish colonel, lord of the fiefdom Lister in Norway, and owner of the Hastrup and Østergaard estates in Denmark.

A member of the younger Kaas family (informally known as Mur-Kaas), one of Denmark's preeminent families of ancient high nobility, he is notable as a war hero during the March across the Belts when he led the defense of Fyn against the Swedes and fell in battle.

King Charles X Gustav of Sweden accompanied his body on foot in honour of his bravery.

Jørgen Kaas and Karen Grubbe were also great-great-great-grandparents of Countess Louise Sophie of Danneskiold-Samsøe (1796–1867), married to Christian August II, Duke of Schleswig-Holstein-Sonderburg-Augustenburg, a member of the royal House of Oldenburg.

Their descendants include Augusta Victoria, German Empress, King Carl XVI Gustav of Sweden, King Constantine II of Greece, Queen Sofía of Spain, the current head of the House of Glücksburg Christoph, Prince of Schleswig-Holstein, the current head of the House of Hanover Prince Ernst August of Hanover and the current head of the House of Hohenzollern Georg Friedrich, Prince of Prussia.
