Bertha of Sulzbach

Bertha of Sulzbach (1110s – August 29, 1159) was the first wife and Empress of Byzantine Emperor Manuel I Comnenus.

She was born in Sulzbach, a daughter of Berengar II, Count of Sulzbach (c. 1080 – 3 December 1125) and his second wife Adelheid of Wolfratshausen. In 1111, Berengar was among the nobles attending the coronation of Henry V, Holy Roman Emperor. He is mentioned among the sureties of documents related to the coronation. In 1120, Berengar is recorded granting a donation to the Prince-Bishopric of Bamberg. He is mentioned as the founder of Berchtesgaden Provostry and Baumburg Abbey. He was also a co-founder of Kastl Abbey. He was one of the rulers who signed the Concordat of Worms (23 September 1122). In August, 1125, Berengar is mentioned in documents of Lothair III, King of the Romans. The death of Berengar is mentioned four months later.

The identity of her mother is mentioned in the "Kastler Reimchronik", Vers 525. Adelheid is mentioned in various other documents of the 12th century as "Countess of Sulzbach", without mentioning her husband. "De Fundatoribus Monasterii Diessenses" contains a rather confused genealogy concerning her two most prominent daughters. Otto II, Count of Wolfratshausen, father of Adelheid, is given as father to Richenza, "Empress" and "Maria, Empress of the Greeks". Richenza was the empress of Lothair III. The author of the text had apparently confused her with Gertrude von Sulzbach, wife of Conrad III of Germany. Maria is probably a confusion for "Irene", the baptismal name of Bertha of Sulzbach, wife of Manuel I Komnenos. Both were actually granddaughters of Otto, children of Berengar and Adelheid. Gertrude was a sister of Bertha.
