The Anscarids or Anscarii or the House of Ivrea were a medieval Frankish dynasty of Burgundian origin which rose to prominence in Italy in the tenth century, even briefly holding the Italian throne.
They also ruled the County of Burgundy in the eleventh and twelfth centuries and it was one of their member who first declared himself a franc-compte or free count.
Their plot failing, Anscar accompanied Guy back to Italy to seek that vacant throne and in gratefulness created the March of Ivrea to bestow on his Burgundian faithful. Anscar's descendants held the march until 1030. Perhaps the most illustrious scion of the house was his grandson Berengar, the first of three Anscarids to be crowned king of Italy.
Berengar seized the throne in 950 after the death of Lothair II. He was opposed, immediately, by Lothair's widow Adelaide, whom he imprisoned after his attempt to force her marriage to his son, Adalbert II, failed. Emperor Otto I came down the peninsula and forced him to do homage in 952. For the next eleven years, Berengar and his co-crowned son governed Italy until Otto finally formally deposed them in 963.
Adalbert tried to continue holding on to his throne, but he was eventually forced to flee back to Burgundy, where he died at Autun. His widow remarried to Otto-Henry, Duke of Burgundy and her son by Adalbert, Otto William, inherited the duchy of Burgundy, but was opposed by Henry I of France, who confiscated the duchy, leaving only a small portion around Dôle to Otto. This was the kernel of the later Free County.
The greatest of the free counts was Renaud III, who, from 1127, utilised the title franc-compte as a sign of independence of German or Imperial authority, but was forced to submit to Conrad III. His daughter and heiress, Beatrice, married Frederick Barbarossa and united the Anscarid inheritance with that of the Hohenstaufen. Burgundy was inherited by her son Otto, who had an Anscarid name.
