     Peter of Courtenay French: Pierre de Courtenay (died 1219) was emperor of the Latin Empire of Constantinople from 1216-1217.

He was a son of Peter of Courtenay (d. 1183), the youngest son of Louis VI of France and his second Queen consort Adélaide de Maurienne. His mother was Elizabeth of Courtenay.

Peter first married Agnes of Nevers, via whom he obtained the three counties of Nevers, Auxerre, and Tonnerre. He took for his second wife, Yolanda of Flanders (d. 1219), a sister of Baldwin and Henry of Flanders, who were afterwards the first and second emperors of the Latin Empire of Constantinople. Peter accompanied his cousin, King Philip Augustus, on the crusade of 1190 and fought (alongside his brother Robert) in the Albigensian Crusade in 1209 and 1211, when he took part in the siege of Lavaur. He was present at the Battle of Bouvines in 1214.

When his brother-in-law, the emperor Henry, died without sons in 1216, Peter was chosen as his successor, and with a small army set out from France to take possession of his throne. Consecrated emperor at Rome, in a church outside the walls, by Pope Honorius III on 9 April 1217, he borrowed some ships from the Venetians, promising in return to conquer Durazzo for them; but he failed in this enterprise, and sought to make his way to Constantinople by land. On the journey he was seized by the despot of Epirus, Theodore Komnenos Doukas, and, after an imprisonment of two years, died, probably by foul means. Peter thus never governed his empire, which, however, was ruled for a time by his wife, Yolanda, who had succeeded in reaching Constantinople. Two of his sons, Robert and Baldwin, in turn held the throne of the Latin Empire.1 Latin Emperor of Constantinople.

King Louis VI of France

M, b. 1 December 1081, d. 1 August 1137
Father*King Philip I of France b. 23 May 1052, d. 30 Jul 1108
Mother*Bertha of Holland
     Louis VI (1 December 1081 – 1 August 1137), called the Fat (French: le Gros), was King of France from 1108 until his death (1137). Chronicles called him "roi de Saint-Denis". The first member of the House of Capet to make a lasting contribution to the centralizing institutions of royal power,[1] Louis was born in Paris, the son of Philip I and his first wife, Bertha of Holland. Almost all of his twenty-nine-year reign was spent fighting either the "robber barons" who plagued Paris or the Norman kings of England for their continental possession of Normandy. Nonetheless, Louis VI managed to reinforce his power considerably and became one of the first strong kings of France since the division of the Carolingian Empire. His biography by his constant advisor Abbot Suger of Saint Denis renders him a fully-rounded character to the historian, unlike most of his predecessors.

.In his youth, Louis fought the Duke of Normandy, Robert Curthose, and the lords of the royal demesne, the Île de France. He became close to Suger, who became his adviser. He succeeded his father on Philip's death on 29 July 1108. Louis's half-brother prevented him from reaching Rheims and so he was crowned on 3 August in the cathedral of Orléans by Daimbert, Archbishop of Sens. The archbishop of Reims, Ralph the Green, sent envoys to challenge the validity of the coronation and anointing, but to no avail.

On Palm Sunday 1115, Louis was present in Amiens to support the bishop and inhabitants of the city in their conflict with Enguerrand I of Coucy, one of his vassals, who refused to recognize the granting of a charter of communal privileges. Louis came with an army to help the citizens to besiege Castillon (the fortress dominating the city, from which Enguerrand was making punitive expeditions). At the siege, the king took an arrow to his hauberk, but the castle, considered impregnable, fell after two years.

Louis VI died on 1 August 1137, at the castle of Béthisy-Saint-Pierre, nearby Senlis and Compiègne, of dysentery caused by his excesses, which had made him obese. He was interred in Saint Denis Basilica. He was succeeded on the throne by his son Louis VII, called "the Younger," who had originally wanted to be a monk.1

Mother*Adélaide de Maurienne b. 1092, d. 1154
     Louis VII, called the Younger or the Young, French: Louis le Jeune (1120 – 18 September 1180), was King of France, the son and successor of Louis VI (hence his nickname). He ruled from 1137 until his death. He was a member of the House of Capet. His reign was dominated by feudal struggles (in particular with the Angevin family), and saw the beginning of the long feud between France and England. It also saw the beginning of construction on Notre-Dame de Paris, the founding of the University of Paris and the disastrous Second Crusade.

Louis VII was born in 1120, the second son of Louis VI of France and Adelaide of Maurienne. As a younger son, Louis VII had been raised to follow the ecclesiastical path. He unexpectedly became the heir to the throne of France after the accidental death of his older brother, Philip, in 1131. A well-learned and exceptionally devout man, Louis VII was better suited for life as a priest than as a monarch.

In his youth, he spent much time in Saint-Denis, where he built a friendship with the Abbot Suger which was to serve him well in his early years as king.

Louis married three times. By Eleanor of Aquitaine, he had:

Marie, married Henry I of Champagne
Alix, married Theobald V of Blois
By Constance of Castile:

Marguerite of France (1158–97), married (1) Henry the Young King; (2) King Béla III of Hungary (1172–96)
Alys (4 October 1160 – c. 1220), engaged to Richard I of England; she married William III Talvas, Count of Ponthieu
By Adele of Champagne:

Philip II Augustus (August 22, 1165 – 1223)
Agnes of France (1171–1240), who was betrothed to Alexius II Comnenus (1180–83) but married (1) Andronicus I Comnenus (1183–85); (2) Theodore Branas (1204).1 The marriage of King Louis VII of France and Eleanor of Aquitaine was annulled in 1152.

     Helie of Burgundy (c.1080 – 28 February 1141) was the daughter of Eudes I and Sibylla of Burgundy.

In June 1095, she married Bertrand of Toulouse, as his second wife. The two had one son, Pons of Tripoli (c.1098–1137).

Bertrand succeeded his father as Count of Toulouse in 1105, and in 1108, he set out for Outremer to claim his father's rights as Count of Tripoli. Helie accompanied him on this expedition, which resulted in the capture of Tripoli in 1109; shortly after, their nephew, William-Jordan died of wounds, giving Bertrand an undisputed claim to Tripoli.

Bertrand died in 1112, and Pons succeeded him in Tripoli. Helie returned to France, where she married William III of Ponthieu in 1115. They had twelve children, including two named Robert, two named William, and two named Enguerrand:

Guy II of Ponthieu (d. 1147)

     Robert de Bellême, 3rd Earl of Shrewsbury (1052–after 1130), also spelled Belleme or Belesme, was an Anglo-Norman nobleman, and one of the most prominent figures in the competition for the succession to England and Normandy between the sons of William the Conqueror. He is also known as Robert II de Montgommery, seigneur of Bellême.

He was the eldest son of Roger of Montgomery, 1st Earl of Shrewsbury and Mabel of Belleme.

Robert's first notable act, as a young man, was to take part in the 1077 revolt of the young Robert Curthose against William the Conqueror, an act he shared with many other Norman nobles of his generation. The rebellion was put down, and the participants pardoned. William did require that ducal garrisons be placed in the important baronial castles, which would make future rebellion much more difficult.

Robert's mother Mabel was killed in 1082, whereupon Robert inherited her property which stretched across the hilly border region between Normandy and Maine. It is due to this early inheritance that Robert has come be known as of Bellême rather than of Montgomery.

William the Conqueror died in 1087, and Robert's first act on hearing the news was to expel the ducal garrisons from his castles. Robert Curthose was the new duke of Normandy, but he was unable to keep order, and Robert of Bellême had a free hand to make war against his less powerful neighbours.

The next year in the Rebellion of 1088, Odo of Bayeux rebelled in an attempt to place Curthose on the English throne in place of William Rufus. At Curthose's request Robert went to England, where he joined in the rebels' defence of Rochester Castle. The rebels were permitted to leave after the surrender of the castle and failure of the rebellion.

Robert returned to Normandy. Odo had preceded him, had obtained the confidence of the duke, and convinced Curthose that Robert was a danger to the security of the duchy. Thus Robert was arrested and imprisoned upon his disembarkation. (The duke's younger brother Henry, who was on the same ship, was also arrested.)

Robert's father Earl Roger came over from England, and, taking over his son's castles, defied Curthose. The duke captured several of the castles, but he soon tired of the matter and released Robert.

Once released, Robert returned to his wars and depredations against his neighbours in southern Normandy. He did help Curthose in putting down a revolt by the citizens of Rouen, but his motive seems to have been in large part to seize as many wealthy townspeople and their goods as possible. Curthose in turn subsequently helped Robert in some of his fights against his neighbours.

In 1094 one of Robert's most important castles, Domfront, was taken over by the duke's brother Henry (later Henry I of England), who never relinquished it and was to be an enemy of Robert for the rest of his life.

Later that year (1094) Robert's father earl Roger died. Robert's younger brother Hugh of Montgomery, 2nd Earl of Shrewsbury inherited the English lands and titles, while Robert inherited his father's Norman properties, which included good part of central and southern Normandy, in part adjacent to the Bellême territories he had already inherited from his mother.

In 1098 Robert's younger brother Hugh died, and Robert inherited the English properties that had been their father's, including the Rape of Arundel and the Earldom of Shrewsbury.

Robert was one of the great magnates who joined Robert Curthose's 1101 invasion of England, along with his brothers Roger the Poitevin and Arnulf of Montgomery and his nephew William of Mortain. This invasion, which aimed to depose Henry I, ended in the Treaty of Alton. The treaty called for amnesty for the participants but allowed traitors to be punished. Henry had a series of charges drawn up against Robert in 1102, and when Robert refused to answer for them, gathered his forces and besieged and captured Robert's English castles. Robert lost his English lands and titles (as did his brothers), was banished from England, and returned to Normandy.

He was one of Curthose's commanders at the Battle of Tinchebrai and by flight from the field avoided being captured as Curthose was. With Normandy now under Henry's rule, he submitted and was allowed to retain his Norman fiefs. But after various conspiracies and plans to free Curthose, Robert was seized and imprisoned in 1112. He spent the rest of his life in prison; the exact date of his death is not known.

Robert married Agnes of Ponthieu, by whom he had one child, William III of Ponthieu, who via his mother inherited the county of Ponthieu.1
