Henry I of France in the context of "Duke of Burgundy"

The Duchy of Burgundy (/ˈbɜːrɡəndi/; Latin: Ducatus Burgundiae; French: Duché de Bourgogne) was a medieval and early modern feudal polity in north-western regions of historical Burgundy. It was a duchy, ruled by dukes of Burgundy. The Duchy belonged to the Kingdom of France, and was initially bordering the Kingdom of Burgundy to the east and south, thus being distinct from the neighboring Free County of Burgundy (modern region of Franche-Comté). The first duke of Burgundy (Latin: dux Burgundiae), attested in sources by that title, was Richard the Justiciar in 918.

In 1004, prince Henry of France, a son of king Robert II of France, inherited the Duchy, but later ceded it to his younger brother Robert in 1032. Robert became the ancestor of the ducal House of Burgundy, a cadet branch of the royal Capet dynasty, ruling over a territory that roughly conformed to the borders and territories of the modern region of Burgundy (Bourgogne). Upon the extinction of the Burgundian male line with the death of Duke Philip I in 1361, the duchy reverted to King John II of France and the royal House of Valois. The Burgundian duchy was absorbed in a larger territorial complex after 1363, when King John II ceded the duchy to his younger son Philip. With his marriage with Countess Margaret III of Flanders, he laid the foundation for a Burgundian State which expanded further north in the Low Countries collectively known as the Burgundian Netherlands. Upon further acquisitions of the County of Burgundy, Holland, and Luxemburg, the House of Valois-Burgundy came into possession of numerous French and imperial fiefs stretching from the western Alps to the North Sea, in some ways reminiscent of the Middle Frankish realm of Lotharingia.

Philip I (c. 1052 – 29 July 1108), called the Amorous (French: L’Amoureux), was King of the Franks from 1060 to 1108. His reign, like that of most of the early Capetians, was extraordinarily long for the time. The monarchy began a modest recovery from the low it had reached during the reign of his father, Henry I, and he added the Vexin region and the viscountcy of Bourges to his royal domaine.

Trinity Abbey, Vendôme, was a Benedictine monastery founded in 1035 in Vendôme by Geoffrey Martel and his first wife, Agnes of Burgundy. It was consecrated on 31 May 1040, one month before Geoffrey became Count of Anjou.

The abbey was under the direct authority of the Pope and nobody else. This fact was accepted by Thierry of Chartres and by King Henry I of France in 1056. In 1063, its abbot was given the rights of being a cardinal. It was often in conflict with the counts of Vendôme and some, like Geoffrey Jordan, were excommunicated.

Robert I (1011 – 21 March 1076), known as the Old or the Headstrong (Old French: Tête-Hardi), was Duke of Burgundy from 1032 to his death. Robert was the third son of King Robert II of France and Constance of Arles. His brother was Henry I of France.

Gervais de Château-du-Loir (1007–1067) was a French nobleman, bishop, and a powerful figure of his time in Northern France. He was Bishop of Le Mans from 1036 and Archbishop of Reims from 1055.

His father was Aimon de Château-du-Loir, whilst his mother was Hildeburge de Bellême, daughter of Yves de Bellême. His maternal uncle, Avesgaud de Bellême, Bishop of Le Mans, raised Gervais and groomed him to succeed to the Bishopric of Le Mans. He was a strong supporter of the family of Blois, and opposed to the Angevins. At one point, he had to seek refuge at the court of William, Duke of Normandy. Henry I appointed him Archbishop of Reims in 1055. As Archbishop, he crowned Philip I of France in 1059. Philip's father, Henry I of France, was then alive but died in 1060. Gervais was then regent with Baldwin V, Count of Flanders until 1066. Gervais died in 1067 and was buried in Reims Cathedral.
