Dietrich III, Count of Holland

- 1039

• Name	Dietrich III
  Relationship	with Robert Alan Roy
  General Information	Dietrich III (also called Dirik or Theodoric or Dirk) was the count with jurisdiction over what would become the county of Holland, often referred to in this period as "West Frisia",  [2]
  Title(s)	993  [2]
  He became the Count of Holland (West Friesland) but was under the regency of his mother until 1005.
  Military	1018  [2]
  Count Dirk built a stronghold at Vlaardingen, in a newly habitable area where many Frisians had recently settled by his invitation. He was not permitted to levy tolls or hinder trade in any way, but eventually he defied imperial rule. Working together with the Frisians now living in the area, he stopped passing ships, demanding payment of tolls. Merchants from the town of Tiel sent alarmed messages to the king and Bishop Adelbold of Utrecht about acts of violence against them by Dirk's men. Emperor Henry then decided to end Dirk III's reign and awarded his lands to Bishop Adelbold. A large imperial army, made up of troops supplied by the various bishops of region, under the command of Godfrey II, Duke of Lower Lorraine, then headed for the stronghold at Vlaardingen. The ensuing Battle of Vlaardingen was a disaster for the imperial army and a tremendous victory for Count Dirk; many of the imperial commanders perished and Duke Godfrey was captured. Following this victory, Dirk III was permitted to keep his lands and he continued levying tolls. Later on, Dirk also managed to acquire more lands east of his previous domains at the expense of the Bishop of Utrecht.
  Miscellaneous	1024  [2]
  After the death of Emperor Henry II in 1024, Dirk supported Conrad II for the succession to the kingship.
  Travel	About 1030  [2]
  It is thought that Dirk III went on pilgrimage to the Holy Land around 1030, hence his nickname of Hierosolymita ("the Jerusalemite" in Latin).
