Rudolf IV of Montfort-Feldkirch

Rudolf IV of Montfort-Feldkirch was the fourth son of Count Hugo IV and Anna of Veringen. Left underage at his father's death in 1310, he grew up under the regency of his uncles, including Rudolf, bishop of Constance.

As the last count of Montfort-Feldkirch he sold the city and lordship of Feldkirch to Duke Leopold III of Austria in 1375, ending Montfort rule over the town. He died later that year and was buried at Feldkirch. His daughter Agnes became countess of Werdenberg-Sargans.
