"Henry II, Margrave of Istria (sometimes called Henry IV), born c.1175 and died 18 July 1228 in Slovenj Gradec (Windischgraz), was a noble from the House of Andechs who ruled the March of Istria and Carniola from 1204 to 1228. He inherited the County of Stein (Kamnik in Upper Carniola), and expanded his domains to the Windic March through marriage. He died childless, and his vast possessions were eventually inherited by his niece Agnes of Merania." - (en.wikipedia.org 06.02.2022)
