Notes:

Floris IV (24 June 1210 The Hague-19 July 1234, Corbie, France), Count of Holland from 1222 to 1234. He was a son of William I of Holland and his first wife, Adelaide of Guelders.

Floris IV succeeded his father in 1222. His regent was Baldwin of Bentheim. He acquired the Land of Altena. He had constant disputes with the bishop of Utrecht, Otto of Lippe, but helped him against the peasants of Drenthe in 1227. Floris was a real knight, who went on crusade against the Stedingers north of Bremen in 1234.

On 19 July 1234, he died at a French tournament held in Corbie, France.

Family and children

He married before 6 December 1224 Matilde of Brabant, daughter of Duke Henry I of Brabant and Mathilde of Flanders also referred to as Maud of Boulogne and Alsace. Their children were:

William II, Count of Holland (1227-1256).
Floris de Voogd (ca. 1228-1258), Regent of Holland in 1256-1258.
Adelaide of Holland (ca. 1230-1284), married, in Frankfurt am Main in 1246, Jean I of Avesnes, Count of Hainaut. Their descendants eventually inherited Holland. She was Regent of Holland in 1258-1263.
Margaret (d. 1277), married c. 1249 to Count Herman I of Henneberg.
Mechtild

Floris married Matilde of Brabant Bef 06 Dec 1224. Matilde (daughter of Henry, I Duke of Brabant and Matilda of Flanders, Duchess of Brabant) was born Abt 1200; died 22 Dec 1267. [Group Sheet]

1. Adelaide of Holland died 1284; was buried 09 Apr 1284, Valenciennes, Hainaut, France.

Notes:

William I (c. 1167, The Hague - 4 February 1222), Count of Holland from 1203 to 1222. He was the younger son of Floris III and Ada of Huntingdon.

Life

William was raised in Scotland. He started a revolt against his brother, Dirk VII and became count in Friesland after a reconciliation. Friesland was considered as a part of Holland by the Counts of Holland. His niece, Ada, Countess of Holland inherited Holland in 1203, but William couldn't accept this. After a civil war (part of the Hook and Cod Wars), which lasted for several years, William won the war. Louis and Ada were supported by the bishop of Liège and bishop of Utrecht, and the count of Flanders. William was supported by the duke of Brabant and by the majority of the Hollanders.

Emperor Otto IV acknowledged him as count of Holland in 1203, because he was a supporter of the Welfs. He and many others changed allegiance to emperor Frederick II after the battle of Bouvines in 1214. He took part in a French expedition against king John of England. The pope excommunicated him for this.

Possibly because of this, William then became a fervent crusader. He campaigned in Prussia and joined in the conquest of Alcácer do Sal. In Europe, he came to be called William the Crazy for his chivalric and reckless behaviour in battle. William conquered the city of Damietta during the Fifth Crusade.

Evolution of the county

There were great changes in the landscape of Holland in the end of the 12th and during the 13th century. Many colonists bought land to turn the swamps into polders. Most of the swamps had been sold, and irrigation had started during the reign of William. Huge infrastructural works were done; the island called Grote Waard was enclosed with dikes all around and a dam was built at Spaarndam. New governmental bodies were created, the so-called water boards, which were charged with the task of protecting the polders against ever-present threat of flooding. Count William granted city rights to Geertruidenberg in 1213, to Dordrecht in 1217, to Middelburg in 1220 and perhaps also to Leiden. In this way he gave an impulse to trade.

Family

Count William was married twice. First, he was married in 1197 at Stavoren to Adelaide of Guelders, daughter of Otto I, Count of Guelders and Richarde of Bavaria. Adelaide died on 12 February 1218 while William was away on crusade. On his return he married secondly, in July 1220, Marie of Brabant, daughter of Henry I, Duke of Brabant and Maud of Boulogne and Alsace. She was the widow of Emperor Otto IV. William and his first wife Adelaide had the following children:

Floris IV, Count of Holland (24 June 1210 The Hague-19 July 1234, Corbie, France).
Otto (d. 1249), Regent of Holland in 1238-1239, Bishop of Utrecht.
William (d. 1238), Regent of Holland in 1234-1238.
Richardis (d. 1262).
Ada (d. 1258), Abbess at Rijnsburg 1239.

William married Adelaide of Guelders 1197, Stavoren, Netherlands. Adelaide (daughter of Otto, I of Guelders and Richardis of Bavaria) was born Abt 1182; died 1218; was buried Rijnsburg Abbey. [Group Sheet]

Notes:

Adelaide of Guelders (c. 1182 - 1218) was the daughter of Count Otto I of Guelders and his wife, Richarda, the daughter of Duke Otto I of Bavaria and Agnes of Loon.

Adelaide died in 1218, while her husband was away on the Fifth Crusade. She was buried in Rijnsburg Abbey.

In 1197 in Stavoren, she married Count William I of Holland. They had five children:

Floris IV (24 June 1210 in The Hague-19 July 1234 in Corbie, France), succeeded his father as Count of Holland
Otto (d. 1249), Regent of Holland in 1238-1239, Bishop of Utrecht
William (d. 1238), Regent of Holland in 1234-1238.
Richarda (d. 1262)
Ada (d. 1258), Abbess at Rijnsburg from 1239 until her death

Notes:

Floris III of Holland (1141 - August 1, 1190), Count of Holland from 1157 to 1190. He was a son of Dirk VI and Sophia of Rheineck, heiress of Bentheim.

Life

On September 28, 1162, he married Ada, sister of king William I of Scotland, also known as William the Lion. The county of Holland adopted from him the rampant lion in the coat of arms and the name of William.

Floris III was a loyal vassal to Frederick I Barbarossa. He accompanied the emperor on two expeditions to Italy in 1158 and 1176-1178. Frederick thanked him by making Floris part of the imperial nobility.

The emperor gave Floris the toll right of Geervliet, the most important toll station in Holland at that time. This was actually the legalisation of an existing situation, because the counts of Holland had charged tolls illegally since the start of the 11th century.

Many farmers came to Holland to turn the swamps into agricultural lands. Dikes and dams were built and the border between Holland and the bishopric of Utrecht had to be determined. There was a dispute between Floris and the bishop of Utrecht about a new dam in the Rhine at Zwammerdam in 1165, which had to be settled by emperor Frederick. The brother of Floris, Baldwin became bishop of Utrecht in 1178.

War broke out between Flanders and Holland. Count Philip of Flanders wanted to have Zeeland. Floris was captured in Brugge and had to accept Flemish overlordship in Zeeland as ransom in 1167.

During his reign Floris III had troubles with West Friesland and a war with Philip count of Flanders concerning their respective rights in West Zeeland, in which he was beaten. In 1170 a great flood caused immense devastation in the north and helped to form the Zuider Zee.

In 1189 Floris accompanied Frederick Barbarossa upon the third Crusade, of which he was a distinguished leader. He died in 1190 at Antioch of pestilence and was buried there.

Two sons of Floris III became Count of Holland: Dirk VII in 1190 and William I in 1203.

Family and children

He married 28 August 1162 Ada of Huntingdon, daughter of Henry of Scotland, 3rd Earl of Huntingdon and Ada de Warenne. Their children were:

Ada (died after 1205), married 1176 Margrave Otto I of Brandenburg.
Margaret (died after 1203), married 1182 Count Dietrich IV of Cleves.
Dirk VII, Count of Holland.
William I, Count of Holland.
Floris (died 1210), bishop of Glasgow.
Baldwin (died 1204).
Robert
Beatrix
Elisabeth
Hedwig
Agnes (died 1228), Abbess at Rijnsburg.

Floris married Ada of Huntingdon 28 Aug 1162, Egmond, Noord-Holland, Netherlands. Ada (daughter of Henry of Huntingdon, Earl of Huntingdon and Ada de Warenne) was born Abt 1146, Scotland; died Aft 1206. [Group Sheet]

Notes:

She married Florent III, Comte de Hollande, son of Dirk VI, Comte de Hollande, circa 1162.

Ada of Huntingdon (circa 1146 - after 1206) was a Scottish noblewoman and Countess of Holland by marriage.

Ada was born in Scotland, the daughter of Henry of Huntingdon (1114-1152) and Ada de Warenne (died circa 1178). Henry was the son of King David I of Scotland and Maud, Countess of Huntingdon, and Ada's siblings include the Scottish kings Malcolm IV and William the Lion.

In 1162 she was asked for her hand in marriage to Floris III, Count of Holland (circa 1132-1190) by the Abbot of Egmond, Holland. Together, the Abbot and Ada traveled back to Holland, where the wedding ceremony occurred, probably in Egmond, on 28 August 1162. Ada received the County of Ross in the Scottish Highlands as a wedding gift.

Ada was not actively involved in the governance of the County of Holland but was occasionally mentioned in documents. Floris, her husband was a loyal ally of the Holy Roman Emperor, Frederick II, and often went with him into battle. Dutch chronicler Melis Stoke states that she supported her son in the war with William of Cleves during the War of Succession. In addition, Ada is known to have read Latin. Ada died after 1206 and was probably buried in the Abbey of Middelburg, to which she had already made donations of £64.

Ada and Floris had 8 or 10 children, of whom some died young, including the following issue:

Ada (died after 1205), married 1176 Margrave Otto I of Brandenburg
Margaret (died after 1203), married 1182 Count Dietrich IV of Cleves
Dirk VII, Count of Holland
William I, Count of Holland
Floris (died 1210), bishop of Glasgow
Baldwin (died 1204)
Robert
Beatrix
Elisabeth
Hedwig
Agnes (died 1228), Abbess at Rijnsburg

Otto — Richardis of Bavaria. [Group Sheet]

Notes:

Dirk VI of Holland (ca. 1114 - 5 August 1157) 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.

Petronilla's regency

When his father died in 1122, Dirk was only 7 years old and his mother, Petronilla, governed the county as regent. In 1123 she supported the uprising of her half-brother, Lothair of Süpplingenburg, Duke of Saxony against Emperor Henry V. After Lothair had been elected king of Germany himself in 1125 he returned Leiden and Rijnland to Holland, which had both been awarded to the Bishop of Utrecht in 1064 (Later on during Dirk's reign the wooden fortifications at Leiden would be replaced by a stone castle). Because Petronilla saw little ability or ambition in Dirk as he grew up, she stalled letting go of the regency when he reached adulthood (fifteen years old), until her favourite son Floris could attempt to take over the county.

Floris the Black

This Floris, called "the Black" (Dutch: de Zwarte) did possess those qualities which his older brother seemed to lack. He openly revolted against him and was from 1129 to 1131 recognised as Count of Holland by, amongst others, King Lothair and Andreas of Kuyk, Bishop of Utrecht. After March 1131 Dirk again appears as count of Holland alongside him, the brothers apparently having reached an agreement. Only a few months later, however, in August 1131 Floris accepted an offer from the West-Frisians to become lord of their entire territory, which reignited the conflict with his brother. After this the people from Kennemerland joined the revolt as well. A year later, in August 1132 King Lothair intervened and managed to reconcile the brothers. This did not pacify the Frisians however, who continued their revolt, which was nonetheless eventually suppressed. Later that year, on 26 October Floris was ambushed near Utrecht and murdered by Herman and Godfried of Kuyk, leaving Dirk to rule the county on his own. King Lothair punished this act by having Herman and Godfried's castle razed and banishing the two. Floris was buried at Rijnsburg Abbey.
Imperial affairs

Count Dirk had supported his relative Lothair of Saxony against Henry V and with his assistance parts of Holland were regained that had been awarded to and occupied by the Bishopric of Utrecht in 1064. Furthermore, with help from King Conrad III and support of the counts of Cleves and Guelders and his brother-in-law Otto II, Count of Rheineck, he was able to get a candidate of his own (Herman of Horne) recognised as bishop of Utrecht.

Ecclesiastical affairs and pilgrimage

Dirk and his mother supported the abbeys of Egmond and Rijnsburg, which flourished in this period. The nunnery at Rijnsburg was established by Petronilla in 1133. Two of her granddaughters, Sophie and Hedwig later joined it, one of them as abbess.

Dirk and Sophie went on a pilgrimage to the Holy Land in 1138 and it was on this pilgrimage that their first son Dirk, called Peregrinus ("Pilgrim"), was born, but he died when he was only 12 years old. On the return journey, in 1139, Dirk visited Pope Innocent II and asked for the abbeys of Egmond and Rijnsburg to be placed under direct papal authority and this request was granted. In this way Dirk removed the Bishop of Utrecht's influence over those abbeys. Dirk's mother, Petronilla, died in 1144 and was buried at Rijnsburg.

In 1155 the Frisians revolted again and plundered the area of Santpoort nearby Haarlem, but they were beaten back by the knights of Haarlem and Osdorp.

In 1156 Count Dirk VI resolved the protracted conflict between the abbeys of Egmond and Echternach, which had been ongoing ever since the establishment of Egmond in 923 by Count Dirk I. At the time of the establishment the Count had granted Egmond the rights over all the churches in the area, which had previously belonged to Echternach. Repeated attempts were made to regain these lost rights, initially with little result, but in 1063 William I, Bishop of Utrecht, decided to split the rights between the two abbeys. This division was unacceptable to Egmond however, and its abbots pressed the counts for compensation. Finally, in 1156, Dirk VI resolved to give all the rights over the churches to Egmond again, compensating Echternach with the rights over the proceeds of the church in Vlaardingen and lands on the island of Schouwen. Although the abbot of Egmond was a witness at the agreement, it seems he may have attended under pressure, as only a little while later he excommunicated both Count Dirk and his son Floris. This perhaps is the reason that Dirk, unlike his forefathers, was not buried at Egmond, but at Rijnsburg.

Family

Count Dirk VI married Sophie of Salm, Countess of Bentheim some time before 1137. She was a daughter of Otto of Salm, Count of Rheineck and Bentheim, son of Hermann of Salm, King of Germany. Dirk and Sophie had (at least) nine children:

Dirk, known as Pilgrim (Peregrinus), born 1138/1139 - died 1151.
Floris, born ca. 1140 - died 1 August 1190 at Antioch (succeeded his father as Floris III, Count of Holland, in 1157).
Otto, born 1140/1145 - died 1208 or after (inherited his mother's county and became Count of Bentheim).
Baldwin, born ca. 1149 - died 30 April 1196 (firstly, Provost at St Maria in Utrecht; secondly, Bishop of Utrecht from 1178 until his death).
Dirk, born ca. 1152 - died 28 August 1197 in Pavia (also became Bishop of Utrecht, in 1197, but died the same year).
Sophie (in 1186 she became abbess of Rijnsburg Abbey, established by her grandmother).
Hedwig, died 28 August 1167 (a nun at Rijnsburg).
Gertrud (died in infancy).
Petronilla.

Also, it was alleged that Count Dirk had fathered an illegitimate son, whose name was Robert.

Dirk — Sophia of Rheineck. Sophia (daughter of Otto, I of Rheineck and Gertrud of Northeim) was born Abt 1120; died 26 Sep 1176, Jerusalem, Israel; was buried Jerusalem, Israel. [Group Sheet]

Notes:

Sophia of Rheineck, also known as Sophie of Salm, Countess of Bentheim (c. 1120 - 26 September 1176 in Jerusalem) was a German noblewoman. Her father was Count Otto I of Rheineck, the son of the anit-king Hermann of Salm. Her mother was Gertrud of Northeim. She was married to Dirk VI, Count of Holland.

Sophia built new churches in the abbeys of Egmond and Rijnsburg. In 1138, she made a pilgrimage to Jerusalem with her husband. During their return journey, they visited the pope in Rome.

After her husband's death, she made a pilgrimage to Santiago de Compostella and to more pilgrimages to Jerusalem in 1173 and 1176. During the latter visit, she died in the St. Mary's hospital of the Teutonic Knights in Jerusalem. She was buried in Jerusalem.

Notes:

He married Ada de Warenne, daughter of William II de Warenne, 2nd Earl of Surrey and Elizabeth de Vermandois, circa 1139. He succeeded to the title of Earl of Huntingdon circa February 1136. He gained the title of Earl of Northumberland in 1139.

Henry of Scotland (Eanric mac Dabíd, 1114 - 12 June 1152) was a prince of Scotland, heir to the Kingdom of Alba. He was also the 3rd Earl of Northumberland and the 3rd Earl of the Honour of Huntingdon and Northampton.

He was the son of King David I of Scotland and Maud, 2nd Countess of Huntingdon. His maternal grandparents were Waltheof, Earl of Northumbria and Huntingdon, (beheaded 1075) and his spouse Judith of Lens.

Henry was named after his uncle, King Henry I of England, who had married his paternal aunt Edith of Scotland (the name Edith gallicised as Matilda after becoming Queen consort in 1100). He had three sons, two of whom became King of Scotland, and a third whose descendants were to prove critical in the later days of the Scottish royal house. He also had three daughters.

His eldest son became King of Scots as Malcolm IV in 1153. Henry's second son became king in 1165 on the death of his brother, reigning as William I. Both in their turn inherited the title of Earl of Huntingdon. His third son, David also became Earl of Huntingdon. It is from the 8th Earl that all Kings of Scotland after Margaret, Maid of Norway claim descent.

On Henry's death, the Earldom passed to his half-brother Simon II de Senlis.

Family

Henry married Ada de Warenne, the daughter of William de Warenne, 2nd Earl of Surrey (died 1138), and Elizabeth of Vermandois, daughter of Hugh of Vermandois, The Great.

Henry married Ada de Warenne Abt 1139. Ada (daughter of William de Warenne, 2nd Earl of Surrey II and Elizabeth of Vermandois, Countess of Leicester) was born Abt 1120; died Abt 1178. [Group Sheet]

Notes:

She married Henry of Huntingdon, Earl of Huntingdon, son of David I 'the Saint', King of Scotland and Maud of Northumberland, circa 1139. She was also known as Adama de Warenne. She was also known as Adeline de Warenne.

Ada de Warenne (or Adeline de Varenne) (c. 1120-1178) was the Anglo-Norman wife of Henry of Scotland, Earl of Northumbria and Earl of Huntingdon. She was the daughter of William de Warenne, 2nd Earl of Surrey by Elizabeth of Vermandois, and a great-granddaughter of Henry I of France. She became mother to two Kings of Scots, Malcolm the Maiden and William the Lion.

Marriage and motherhood

Ada and Henry were married in England in 1139. They had seven children:

Malcolm IV, King of Scots.
William the Lion, King of Scots
Margaret of Huntingdon married 1) Conan IV, Duke of Brittany and 2) Humphrey III de Bohun.
David of Scotland, Earl of Huntingdon married Mathilda (Maud) of Chester. Through their daughter, Isobel, they were the direct ancestors of the renowned Scottish King, Robert the Bruce.
Matilda of Huntingdon, born and died 1152.
Marjorie of Huntingdon, married Gille Críst, Earl of Angus.
Ada of Huntingdon, married Count Floris III of Holland.

As part of her marriage settlement, the new Countess Ada was granted the privileges of Haddington, amongst others in East Lothian. Previously the seat of a thanage Haddington is said to be the first Royal burgh in Scotland, created by Countess Ada's father-in-law, David I of Scotland, who held it along with the church and a mill.

In close succession both her husband and King David died, in 1152 and 1153 respectively. Following the death of Henry, who was buried at Kelso Abbey, King David arranged for his grandson to succeed him, and at Scone on 27 May 1153, the twelve year old was declared Malcolm IV, King of Scots. Following his coronation, Malcolm installed his brother William as Earl of Northumbria (although this county was "restored" to King Henry II of England by Malcolm in 1157), and the young dowager-Countess retired to her lands at Haddington.

On Thursday 9 December 1165 King Malcolm died at the age of 25 without issue. His mother had at that time been attempting to arrange a marriage between him and Constance, daughter of Conan III, Duke of Brittany, but Malcolm died before the wedding could be celebrated.[5] One of Ada's daughters, Margaret, was married twice:

(1) 1160, Conan IV, Duke of Brittany, Earl of Richmond (d.1171)
(2) Humphrey III de Bohun of Trowbridge, Wiltshire, Hereditary Constable of England.

Following his brother's death Ada's younger son William became King of Scots at the age of twenty two. William the Lion was to become the longest serving King of Scots until the Union of the Crowns in 1603.

Church patroness

Religious houses were established in Haddington at an early date. They came to include the Blackfriars (who came into Scotland in 1219) and most notably the Church of the Greyfriars, or Minorites (came into Scotland in the reign of Alexander II), which would become famous as "Lucerna Laudoniae"- The Lamp of Lothian, the toft of land upon which it stands being granted by King David I of Scotland to the Prior of St. Andrews (to whom the patronage of the church of Haddington belonged). David I also granted to the monks of Dunfermline "unam mansuram" in Haddington, as well as to the monks of Haddington a full toft "in burgo meo de Hadintun, free of all custom and service."

Ada devoted her time to good works, improving the lot of the Church at Haddington, where she resided. Countess Ada gave lands to the south and west of the River Tyne near to the only crossing of the river for miles, to found a Convent of Cistercian Nuns ("white nuns") dedicated to St. Mary, in what was to become the separate Burgh of Nungate, the extant remains are still to be seen in the ruined parish church of St. Martin. The nunnery she endowed with the lands of Begbie, at Garvald and Keith Marischal amongst other temporal lands. Miller, however, states that she only "founded and richly endowed a nunnery at the Abbey of Haddington" and that "Haddington, as demesne of the Crown, reverted to her son William the Lion upon her death".

Haddington seat

According to inscriptions within the town of Haddington, Countess Ada's residence was located near the present day County buildings and Sheriff Court. Countess Ada died in 1178 and is thought to be buried locally. Her remaining dower-lands were brought back into the Royal desmesne and William the Lion's wife, Ermengarde de Beaumont, is said to have taken to her bed in Countess Ada's house to bear the future Alexander II. Miller states that when the future King was born in Haddington in 1198 it took place "in the palace of Haddington".

Notes:

Otto I (1117 - 11 July 1183), called the Redhead (German: der Rotkopf), was Duke of Bavaria from 1180 until his death. He was the first Bavarian ruler from the House of Wittelsbach, a dynasty which reigned until the abdication of King Ludwig III of Bavaria in the German Revolution of 1918.

Life

Duke Otto I was probably born at Kelheim, the son of Count Palatine Otto IV of Wittelsbach and Heilika of Pettendorf-Lengenfeld, a granddaughter of the Hohenstaufen duke Frederick I of Swabia. He was the brother of Archbishop Conrad I of Mainz and Salzburg. Upon the death of his father in 1156, he succeeded him as Count palatine of the Bavarian duchy, then under the rule of Henry the Lion, a scion of the Welf dynasty.

As one of the best knights in the employ of Emperor Frederick Barbarossa in 1155 he had prevented a defeat of the Emperor near Verona, where the army caravan was ambushed on the way back to Germany after the coronation at Rome . In the Dominium mundi conflict between emperor and pope culminating at the 1157 Reichstag of Besançon (Bisanz), fiery Otto could only be kept from smiting the papal legate Cardinal Rolando Bandinelli by the personal intervention of Frederick.

He was finally rewarded with the duchy of Bavaria on 16 September 1180, after the deposition of Duke Henry the Lion. However with the separation of Styria under Duke Ottokar IV in the same year, Bavaria lost the last of her southeastern territories. With the support of the emperor and his brother Conrad, Otto was able to secure the rule of his dynasty from the wary Bavarian nobility. His descendants ruled Bavaria for the next 738 years.

In 1183 Otto accompanied Emperor Frederick to sign the Peace of Constance with the Lombard League and died suddenly on the way back at Pfullendorf in Swabia. He was succeeded by his only surviving son Louis. Otto's mortal remains are buried in the crypt of Scheyern Abbey.
