The Hohenstaufen, also called Staufer, was a noble dynasty of unclear origin that rose to rule the Duchy of Swabia from 1079 and to royal rule in the Holy Roman Empire during the Middle Ages from 1138 until 1254. The most prominent kings Frederick I (1155), Henry VI (1191) and Frederick II (1220) ascended the imperial throne and also ruled Italy and Burgundy. The non-contemporary name is derived from a family castle on the Hohenstaufen mountain at the northern fringes of the Swabian Jura near the town of Göppingen. Under Hohenstaufen reign the Holy Roman Empire reached its greatest territorial extent from 1155 to 1268.
