The Bishopric of Utrecht was an ecclesiastical principality of the Holy Roman Empire in the Low Countries, in the present-day Netherlands. From 1024 to 1528, as one of the prince-bishoprics of the Holy Roman Empire, it was ruled by the bishops of Utrecht.
The counts of Holland ruled over the County of Holland in the Low Countries between the 10th and the 16th century.
The County of Holland was a state of the Holy Roman Empire and from 1433 part of the Burgundian Netherlands, from 1482 part of the Habsburg Netherlands and from 1581 onward the leading province of the Dutch Republic, of which it remained a part until the Batavian Revolution in 1795. The territory of the County of Holland corresponds roughly with the current provinces of North Holland and South Holland in the Netherlands.
Floris III was the count of Holland from 1157 to 1190. He was a son of Dirk VI and Sophia of Rheineck, heiress of Bentheim.
Saint Wolbodo was the bishop of Liège from 1018 to 1021.
Dirk V was Count of Holland from 1061 to 1091.
Dirk VI was Count of Holland between 1121 and 1157, at first, during his minority, under the regency of his mother Petronilla. He was the son of Count Floris II. After his death he was succeeded by his eldest son Floris III. He married Sofie of Salm, Countess of Rheineck and Bentheim. She was heiress of Bentheim, which she ruled together with her husband and which was inherited by the couple's second son Otto after his parents' death.
Dirk VII was the count of Holland from 1190 to 1203. He was the elder son of Floris III and Ada of Huntingdon.
Dirk IV was Count of Holland from 1039 to 1049. Dirk's date of birth is unknown but it was probably ca. 1030 or shortly before, he was described as "adolescent" at the time of his death. His base of operations was the stronghold his father built at Vlaardingen. Contemporary chroniclers referred to him as "Theodericus de Phlardirtinga" (Vlaardingen) and as margrave thereof. The exact extent of his domain is not known, but at one time or another it stretched north to at least Rijnsburg and east to roughly Aalburg.
The (First) Battle of Vlaardingen was fought on 29 July 1018 between troops of the Holy Roman Empire and West Frisia. As a result of a trade dispute, Emperor Henry II sent an army towards West Frisia to subdue the rebellious Count Dirk III. However, the Imperial army was decisively defeated and fled in panic.
William I was bishop of Utrecht between 1054 and 1076. He was a typical representative of the German imperial system in which bishops were the main officials of the empire. He was a loyal follower of king Henry IV of Germany. William was appointed when a war was going on against West Frisia, which was resisting imperial authority. The imperial army conquered large parts of West Frisia in 1061, when Dirk V became count. King Henry gave the whole county to the bishopric of Utrecht in 1064. The whole of West Frisia was conquered in 1076 with the help of duke Godfrey III.
Adalbold II of Utrecht was a bishop of Utrecht (1010–1026).
Gertrude of Saxony, also known as Gertrude Billung, was a countess of Holland by marriage to Floris I, Count of Holland, and countess of Flanders by marriage to Robert I, Count of Flanders. She was regent of Holland in 1061-1067 during the minority of her son Dirk V, and regent of Flanders during the absence of her spouse in 1086–1093.
Gerolf or Gerulf was the second count of this name who is attested in the area of Friesland. Gerolf's main area of power seems to have been in Kennemerland. Count Gerolf is often regarded as the founder of the County of Holland, although the actual name "Holland" is from a later time. His ancestry is unclear, but he may have been a son or, more likely, a grandson of the earlier Gerolf, who was a count in the area of Frisia at the time of the reign of Emperor Louis the Pious and who later joined a monastery. The earlier Gerolf died in 855. There is some limited and vague evidence that this earlier Gerolf was a son of a certain Theodoric, who in turn supposedly descended from the Frisian king Redbad. Count Gerolf is often identified as the father of Count Dirk I and seen as the founder of the first house of the Counts of Holland, which ruled the county until it was inherited by John II of Hainaut in 1299.
Frisian freedom was the absence of feudalism and serfdom in Frisia, the area that was originally inhabited by the Frisians. Historical Frisia included the modern provinces of Friesland and Groningen, and the area of West Friesland, in the Netherlands, and East Friesland in Germany. During the period of Frisian freedom the area did not have a sovereign lord who owned and administered the land. The freedom of the Frisians developed in the context of ongoing disputes over the rights of local nobility.
Dirk II or Theoderic II was a count in West Frisia, and ancestor of the counts of Holland. He was the son and heir of Dirk I and his wife Geva.
The Lordship of Frisia or Lordship of Friesland was a feudal dominion in the Netherlands. It was formed in 1498 by King Maximilian I and reformed in 1524 when Emperor Charles V conquered Frisia.
