Amadeus III of Montfaucon

Amadeus III of Montfaucon (c. 1207–1280) was lord of Montfaucon, Orbe and Échallens, son of Count Richard III of Montbéliard and Agnes of Burgundy. After the Zähringers died out in 1218 he expanded his lands and succeeded his father around 1230. In 1247 he married Matilda, Countess of Saarbrücken.

In 1255 Hugh of Chalon granted him Orbe's other half in exchange for other rights; Amadeus enclosed Orbe with walls. He disputed rights at Yverdon with Peter II of Savoy but sold them to Peter in 1260. He died on 15 January 1280.
