History
Origins
The Agoult (or Agoult-Simiane) family is first mentioned in a document dated 992, [1] [2] a relatively late appearance [1] in the sources compared with other regional noble families. [2]
The act of 14 November 992 records a donation by Garac of Castellane-Lacoste to Imbert (or Humbert I) [1] of Agoult as compensation for the murder of Imbert’s father. [3] At the request of Bishop Thierry, Imbert received several allodial estates. [3]
The domain of the Agoult-Simiane family appears to have consisted primarily of allodial lands, that is, properties held free of seigneurial obligations, located around Apt [1] (in present-day Vaucluse) from the 10th century onward. [4] Their possessions lay mainly to the north of the county of Apt, where they controlled several fortified sites ( castra ) on the Viens plateau, including Viens and Alpester, as well as Caseneuve, and Castillon, [4] [1] where a monastery known as the monasteriolum of Saint Martin was established. [5] To the northeast, their influence extended over the Albion plateau, including Sault, Simiane, and Banon. [4] [1] To the west, along the boundary between the counties of Apt and Cavaillon, they held the castra of Goult and Gordes, as well as the villae of Beaumettes and Sorguette. [6] [1] The establishment and maintenance of this territorial control involved conflicts, notably with the Castellane-Lacoste family, allies of the viscounts of Cavaillon. [7] The earliest documented reference to this rivalry dates from the act of 992. [1]
The historian Jean Barruo, in his study L'influence de saint Mayeul et de ses proches dans la renaissance du XIe siècle, associated several landholding families of Apt and its surrounding region with the lineage of Saint Maiolus of Cluny. Building on this work, Jean Méhu traced this lineage back to Fulcher the Elder [ fr ], the grandfather of Saint Mayeul, through Fulcher’s younger son Eyric. [8] In this interpretation, Imbert (or Humbert I) is identified as one of the five sons of Eyric, brother of Mayeul. According to this hypothesis, the estates held by these families would have originated from the extensive patrimony of Fulcher the Elder, a major landowner of Gallo-Roman origin who, by the mid-8th century, possessed numerous villae in Provence, particularly in the pagi of Riez, Sisteron, Fréjus, Apt, and Venasque. [8]
The medievalist Eliana Magnani questioned this analysis, considering the proposed connections to be uncertain. [9] She argued that although the Agoult family held property in Apt, these possessions were not necessarily inherited and may instead have been acquired through later appropriation. [9]
Cognomina
In a study on naming practices and the transmission of power in the Provençal aristocracy, Florian Mazel [ fr ], building on earlier work by Poly, [10] observes that the earliest members of the Agoult family adopted toponymic surnames only from the 12th century, relatively late compared with the emergence of castral lordships. [11] He notes that the cognomen “d’Agoult,” which became hereditary, is attested from the early 12th century, [11] with its earliest known occurrence dating to 1094. [12] [11]
During the mid-11th century, family members were initially identified by the toponymic surname “d’Apt.” [12] [11] This designation was soon replaced by “d’Agoult,” and from 1126 onward by “de Simiane.” [12] [11]
In the main line, some members used the cognomen “de Simiane” in addition to “d’Agoult.” [12] A lesser-known secondary branch adopted the cognomen “de Viens” [12] and became extinct in the 13th century. [12]
According to Mazel, the spread of hereditary surnames did not immediately end the reuse of paternal given names. This practice continued during the 12th century and gradually stabilized in the 13th century [12] in the form of compound names, combining the individual’s given name with that of the father. [11]
The lineage name (Leitname) Imbert, used by the earliest generations, gradually disappeared, except within a secondary branch. [11] From the beginning of the 12th century, new given names became established within the family, notably Raimbaud, Guiran, Bertran, Rostaing, and Raimon. [11] Mazel notes that the cognomen “d’Agoult” is attested only in association with the given names Rostaing, Raimon, and Raimbaud, whereas “de Simiane” is associated exclusively with Guiran, despite the fact that seigneurial rights over the castra of Goult and Simiane continued to be exercised jointly by different branches of the family. [11]
Rise of the family
The rise of the Agoult family began around the early 11th century with its establishment in Apt. [2] The family appears to have supported Church reform, [13] although Mazel emphasizes that this may have been part of a broader strategy in its power struggle with other aristocratic families. [13] Their possessions, combined with an alliance with Raimbaud of Nice [ fr ] (Raimbaud of Reillanne) from the viscountal lineage of Nice-Orange, enabled the family to assume a protective role over the Church of Apt. [13] Early members were integrated into the count’s entourage and exercised influence over the episcopatus of Apt. [2]
Guillem (or Guillaume) I (died c. 1035) married Azalaïs (or Adélaïde), [14] likely of Reillanne. [15] Their son, [15] Alfant [ fr ], became bishop of Apt [16] in early 1048, under the support of Raimbaud of Nice [ fr ]. [13] Several family members participated in the reconstruction of the cathedral, establishing it as a significant religious institution. [16] [5]
In 1056, Alfant’s brothers, Rostaing (or Rostang) and Guillaume, co-lords of Apt, donated the monastery of Saint Peter [ fr ] to the cathedral. [5]
Rostaing (1031–late 11th century) married, in a second marriage, Gisla (or Gisle), daughter of Raimbaud of Nice. Their son, Laugier, later succeeded his uncle as bishop of Apt. [15] [17] [14]
12th–13th century: emergence of the branches
The Agoult-Simiane family gave rise to several branches.
Raimbaud, son of Rostaing (or Rostang), [15] married Sancia (or Sancie), [15] Lady of Simiane. [18] [14] Their son, Guiran (or Guirand), [15] adopted the name of Simiane [18] and founded the Simiane branch [ fr ]. [18] A second son, Bertrand, is considered the possible father of Raimon (or Raymond), a knight and lord of Agoult and the valley of Sault, from whom this lineage is documented. [18]
Raimon (or Raymond), whose lineage is documented, married Isoarde, daughter of Isoard II, count of Die. [19] [18] In July 1178, he attended the coronation of Emperor Frederick Barbarossa as King of Burgundy in Arles. [19] Following this event, he received an imperial charter confirming his feudal jurisdiction over the valley of Sault and recognizing his rights to collect tolls by land and water within the county of Die. [19] The couple had three sons: Raimon (or Raymond) II of Agoult, Bertrand I of Mison, and Isnard I of Entrevennes. [19] [18] Isnard founded the senior branch of the family in Provence, while Raimon II established a branch known as the lords of Beaurières in Dauphiné. [18]
In 1182, Raimbaud of Agoult transferred the castles of Montfort, Arnoux, and Peyruis, along with his possessions in the diocese of Sisteron, to William IV, count of Forcalquier [ fr ], in exchange for a guarantee of 5,000 sous. [20]
Mabille of Agoult, known as of Entrevennes, married Bergundio (or Burgundion), a member of the viscountal family of Marseille [ fr ] and lord of Trets and Ollières. [21] [22] Their son, Isnard, adopted his mother’s name and arms, founding the Agoult d’Ollières family. [21] [22]
At the beginning of the 13th century, a branch of the Agoult family settled in the region of Sisteron (Mison), giving rise to the Agoult family of Dauphiné. By the early 17th century, this family became established in the Grenoble region through marriage. Hector of Agoult, Baron of Montmaur and councillor at the Parliament of Dauphiné, married Uranie, [23] the granddaughter of Soffrey de Calignon, chancellor to the King of Navarre. The Dauphiné branches were divided into three main lines: Agoult-Montmaur, which became extinct with Count Charles Louis Constant d’Agoult (1790–1875); the Voreppe branch, including its offshoots of La Varenne and Beauplan, which became extinct with Hector d’Agoult [ fr ] (1860–1915); and the Beauvesin branch, which became extinct in 1837. [24]
The Agoult family became extinct in the male line in 1915 with the death of Hector d’Agoult [ fr ], deputy for Senegal. He had married Valentine d’Estampes in 1891 and had three sons, who died in early childhood, and one daughter, Clémentine (1897–1991). In 1924, Clémentine married Antoine, Baron Séguier (1891–1978). [25] In 1963, [26] their three sons were authorized to resume the Agoult name, resulting in the combined surname Séguier d’Agoult.
