1187 To 1439
Adalbert, son of Conrad of Zähringen, inherited his father's possessions around the castle Teck between Kirchheim and Owen. After the death of his brother Berthold IV, Duke of Zähringen in 1186, Adalbert adopted the title of "Duke of Teck".
In the 13th century, the family divided into the lines of Teck-Oberndorf and Teck-Owen. The Dukes of Teck-Oberndorf died out in 1363 and Frederick of Teck-Owen sold their possessions to the Count of Hohenberg. In 1365, the Dukes of Teck-Owen came into the possession of Mindelheim but had to sell their lands around the castle Teck to the Counts of Württemberg in 1381 (see Kirchheim unter Teck). The last member of that line, Louis of Teck, Patriarch of Aquileia from 1412, died in 1439.
