Baldwin van Holland( died April 30, 1196 in Mainz) was a bishop of Utrecht from 1178 to 1196 Baldwin was the son of Dirk VI, Count of Holland and Sophia of Rheineck, and brother to counts Otto van Bentheim and Floris III, Count of Holland.
Before Baldwin became bishop of Utrecht, he had been Archbishop of Bremen and chaplain of Henry the Lion.
With a relative as Bishop, the count of Holland was about to expand his power in Utrecht.
During his rule Baldwin was involved in struggles with Otto I, Count of Guelders over the Veluwe and Salland, and with the lords of Groningen and Coevorden.
These wars resulted in numerous raids and plunders in the Oversticht, which weighed heavily on the bishopric's finances.
After his death Baldwin was interred in St. Martin's Cathedral, Utrecht.
Floris I, Count of Holland
Floris I of Holland( born c. 1017 in Vlaardingen – killed June 28, 1061 in Guelders( Gelderland), Netherlands was Count of Holland, then called Frisia west of the Vlie, from 1049 to 1061.
He was a son of Dirk III and Othelindis.
He succeeded his brother Dirk IV, Count of Holland, who was murdered in 1049.
He was involved in a war of a few Lotharingian vassals against the imperial authority.
On a retreat from Zaltbommel he was ambushed and killed in battle at Nederhemert( called Hamerth at the time), on 28 June 1061.
Adelaide of Holland
Adelaide of Holland( – buried 9 April 1284), Countess of Hainaut, was a Dutch regent.
She was a daughter of Floris IV, Count of Holland and Matilda of Brabant.
She was also a sister of William II, Count of Holland and King of Germany.
She acted as regent for her nephew Count Floris V during his minority.
Dirk V, Count of Holland
Dirk V (1052 – June 17, 1091) was Count of Holland (which was called Frisia at that time) from 1061 to 1091.
Dirk V succeeded his father,
Floris I, under the guardianship of his mother, Gertrude of Saxony.
William I, Bishop of Utrecht, took advantage of the young ruler, occupying territory that he had claimed in Holland.
William's claim was confirmed by two charters of the emperor Henry IV.
(April 30, 1064 and May 2, 1064).
Dirk only retained possession of lands west of the Vlie and around the mouths of the Rhine.
Gertrude and her son withdrew to the islands of Frisia (Zeeland), leaving William to occupy the disputed lands.
In 1063 Gertrude married Robert of Flanders (Robert the Frisian), the second son of Baldwin V of Flanders.
Baldwin gave Dirk the Imperial Flanders as an appanage - including the islands of Frisia west of the Frisian Scheldt river.
Robert then became his stepson's guardian, gaining control of the islands east of the Scheldt.
Robert managed to conquer Kennemerland (north of North Holland), but held it only briefly.
Robert therefore, in both his own right and that of Dirk, was now the ruler of all Frisia.
The death of his brother Baldwin VI in 1070 led to civil war in Flanders.
The claim of Robert to the guardianship of his nephew Arnulf III was disputed by Richilde, Countess of Mons and Hainaut, the widow of Baldwin VI.
The issue was decided by Robert's victory at Cassel (February 1071), where Arnulf was killed and Richilda taken prisoner.
The war in Holland and Frisia became part of a large conflict from 1075 onwards.
The pope had excommunicated the emperor.
The bishop of Utrecht supported the emperor, while the count of Holland supported Pope Gregory VII and anti-king Rudolphe.
While Robert was thus engaged in Flanders, an effort was made to recover the County of Holland and other lands now held by William of Utrecht.
The people rose in revolt, but were brought back under Episcopal rule by an army under the command of Godfrey IV (the Hunchback), duke of Lower Lorraine, by order of the emperor (Henry IV).
In 1076, at the request of William, Duke Godfrey visited his domains in the Frisian borderland.
At Delft, the duke was murdered by revolutionaries (February 26, 1076).
William of Utrecht died on April 17, 1076.
Dirk V, now managing his own estate, was quick to take advantage of this favorable juncture.
With the help of Robert (his stepfather) he raised an army and besieged Conrad of Utrecht, the successor of William, in the castle of Ysselmonde, taking him prisoner.
The bishop purchased his liberty by surrendering all claim to the disputed lands.
Dirk V was succeeded by Floris II upon his death in 1091.
He was buried in the Egmond Abbey.
Gertrude of Saxony

She was the sister of Dirk VII, Count of Holland and William I, Count of Holland.
In 1176 she married Otto I of Brandenburg, becoming Margravine of Brandenburg until his death in 1184.
This was Otto's second marriage.
He had been married to Judith of Poland.
Otto already had two sons from his marriage to Judith, Otto( who later succeeded his father as Margrave of Brandenburg) in 1149, and Henry( who inherited the Counties of Tangermünde and Gardelegen) in 1150.
Ada and Otto had a son named Albert II who would in time succeeded his half- brother Otto II as Margrave of Brandenburg in 1205.
