Conrad's son Henry had been crowned king in 1028.

Around this time, due to Henry's and Gisela's requests, Ernest had been set free, although he was not restored to his full powers as duke.

Ernest is offered these powers at the Diet of Easter 1030, if he will crack down on the enemies of Conrad.

Ernest's refusal to do so, especially against his friend Werner von Kyburg, results in his final downfall.

He is stripped of his title as duke.

Only a few months later, while battling the people of the Bishop of Constance, both Ernest and Werner are killed.

Ernest is buried in Constance.

The Duchy of Swabia passes to his younger brother Herman, who at this time is still a minor.
