Overview
Bertha of Holland ( 1055 – 15 October 1094), also known as Berthe or Bertha of Frisia and erroneously as Berta or Bertrada, was Queen of France from 1072 until 1092, as the first wife of King Philip I of France. Bertha's marriage to the king in 1072 was a result of peace negotiations between him and her stepfather, Count Robert I of Flanders. After nine years of childlessness, the royal couple had three children, including Philip's successor, Louis VI. Philip, however, grew tired of his wife by 1090, and repudiated her in 1092 in order to marry the already married Bertrade of Montfort. That marriage was a scandal since both Philip and Bertrade were already married to other people, at least until Queen Bertha died the next year.
Early life
Bertha was the daughter of Count Floris I of Holland and Gertrude of Saxony. Bertha had six siblings and both of her parents came from large families. Her father ruled a territory vaguely described as "Friesland west of the Vlie", which is where Bertha spent her childhood. Count Floris I was assassinated in 1061, and two years later her mother remarried to Robert of Flanders. Robert, now known as Robert the Frisian, became guardian of Bertha and her six siblings. In 1070, Robert the Frisian became involved in a war with King Philip I of France over succession to the County of Flanders. Within two years, Robert and Philip concluded a peace treaty which was to be sealed by a marriage; Robert's own daughters were too young, but their half-sister Bertha was just the right age. Robert thus agreed to the marriage of his stepdaughter to King Philip. Bertha married Philip, thus becoming queen of the Franks, probably in 1072.
