Duke of Teck

The Duke of Teck was, in medieval times, a title borne by the head of a branch line of the German ducal House of Zähringen from 1187 to 1439, known historically as the first House of Teck. His territory was centered on Teck Castle in Swabia.

The title was recreated in 1871 in the Kingdom of Württemberg for a cousin of its king, Charles I, whose descendants settled in the United Kingdom and married into the British Royal Family.

Adalbert I, son of Duke Conrad I of Zähringen, inherited his father's Swabian possessions around Teck Castle between Kirchheim and Owen. After the death of his brother Duke Berthold IV in 1186, Adalbert adopted the title of "Duke of Teck". His descendant Duke Conrad II upon the death of King Rudolph I of Germany in 1291 even became a candidate for the election as King of the Romans, but probably was slain by his opponent Siegfried of Westerburg, Archbishop of Cologne, the next year.

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 Counts 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. The last member of that line, Louis of Teck, Patriarch of Aquileia from 1412, died in 1439.
