The origin of the House of Hohenstaufen in the [[Duchy of Swabia]] has not been conclusively established. As the name came from the [[Hohenstaufen Castle]] (built in 1105) Conrad's great-grandfather Frederick of Staufen was a count in the [[Nördlinger Ries|Riesgau]] and in 1053 became Swabian [[Count palatine]]. His son Frederick of Buren probably resided near present-day [[Wäschenbeuren]] and about 1050 married Countess Hildegard of [[Eguisheim|Egisheim]]-[[County of Dagsburg|Dagsburg]] from [[Alsace]].<ref name="Middleton2015"/>
  
Conrad's father took advantage of the conflict between King Henry IV of Germany and the Swabian duke [[Rudolf of Rheinfelden]] during the [[Investiture Controversy]]. When Rudolf had himself elected German [[anti-king]] at [[Forchheim]] in 1077, Frederick of Hohenstaufen remained loyal to the royal crown and in 1079 was vested with the Duchy of Swabia by Henry IV, including an engagement with the king's daughter [[Agnes of Waiblingen|Agnes]]. He died in 1105, leaving two sons, Conrad and his elder brother [[Frederick II, Duke of Swabia|Frederick&nbsp;II]], who inherited the Swabian ducal title. Their mother entered into a second marriage with [[House of Babenberg|Babenberg]] margrave [[Leopold III, Margrave of Austria|Leopold III of Austria]].<ref name="Ziegler2008">{{cite book|author=Wolfram Ziegler|title=König Konrad III.
