He was the second son of
Berthold IV, Duke of Merania and
Agnes of Rochlitz, daughter of
Dedi III, Margrave of Lusatia of the
House of Wettin. After the death of his father in 1204, Henry took over the dignity of Margrave of Istria-Krain and the possessions situated south of the
Danube. In Istria itself, the
Republic of Venice made life so hard, they virtually dominated the peninsula. The policies of their Doge,
Enrico Dandolo, had left a powerful mark on the region. And as trade and influence spread towards Venice, Istria grew weaker. Earlier in 1207, Henry II married Sophie, daughter and heir of Count Albert of
Weichselburg (died 1209) in modern
Slovenia, in which the Andechs spent huge wealth in the
Windic March. The marriage would remain childless. Then, in 1208, he had the misfortune of being in the wrong place at the wrong time: he became complicit in the murder of
King Philip of Swabia, after the wedding of his oldest brother,
Otto I, Duke of Merania and his bride
Beatrice II, Countess of Burgundy at
Bamberg, the seat of his second eldest brother,
Ekbert, Bishop of Bamberg and the one who presided over the wedding. Today this incident is regarded a disgrace on the part of the
House of Wittelsbach, but the rapid decline in support of the house of Andechs saw Henry II and Bishop Ekbert lose all rights, properties, dignities and revenues and had to flee to their sister,
Gertrude, Queen of Hungary, in
Hungary in 1209 for safety. In 1211, Ekbert could return to his possessions, but Henry II could only regain the Windic March; while his Tyrolean and Bavarian possessions remained lost to him. Although he had a connection with
Aquileia – his younger brother
Berthold was Patriarch there from 1218 to 1251 – and
Leopold VI, Duke of Austria, he was mainly limited as a privateer on his and Sophie's possessions in later Lower Styria and Krain. In 1220, he was "allowed" participation as a witness in the confirmation of the grant of his former Mark to Berthold. Henry was referred to as
ispán of
Moson County in Hungary in 1225. In May 1228, an agreement between Henry II and
Ludwig I, Duke of Bavaria, whom had taken his most of his possessions, was made. Some of his lands and rights were returned, but then in July, death suddenly overtook him in
Windischgraz. He was buried in Dießen Abbey. His old Bavarian possessions were probably inherited by his brother Otto, while the Weichselburg lands remained shortly with Sophie. ==References==
