The Treaty of Verdun, agreed in August 843, divided the Frankish Empire into three kingdoms between Lothair I, Louis II and Charles II, the surviving sons of the emperor Louis I, the son and successor of Charlemagne. The treaty was concluded following almost three years of civil war and was the culmination of negotiations lasting more than a year. It was the first in a series of partitions contributing to the dissolution of the empire created by Charlemagne and has been seen as foreshadowing the formation of many of the modern countries of western Europe.
Lothair I was a 9th-century Carolingian emperor and king of Italy (818–855) and Middle Francia (843–855).
The Treaty of Mersen or Meerssen, concluded on 8 August 870, was a treaty to partition the realm of Lothair II, known as Lotharingia, by his uncles Louis the German of East Francia and Charles the Bald of West Francia, the two surviving sons of Emperor Louis I the Pious. The treaty followed an earlier treaty of Prüm which had split Middle Francia between Lothair I's sons after his death in 855.
The Free County of Burgundy was a medieval feudal state ruled by a count from 982 to 1678. It was also known as Franche-Comté, from French: franc comte meaning 'free count', and was located in the modern region of Franche-Comté. It bordered the Duchy of Burgundy to the west, which was part of France from 843.
Hugh, known as Hugh of Arles or Hugh of Provence, was the king of Italy from 926 until his death. He belonged to the Bosonid family. During his reign, he empowered his relatives at the expense of the aristocracy and tried to establish a relationship with the Byzantine Empire. He had success in defending the realm from external enemies, but his domestic habits and policies created many internal foes and he was removed from power before his death.
Boso was a Frankish nobleman of the Bosonid family who was related to the Carolingian dynasty and who rose to become King of Lower Burgundy and Provence.
The Kingdom of Lower Burgundy, also called Cisjurane Burgundy, was a historical kingdom in what is now southeastern France, so-called because it was lower down the Rhône Valley than Upper Burgundy. It included some of the territory of the Kingdom of Arelat.
The Kingdom of Burgundy, known from the 12th century as the Kingdom of Arles, also referred to in various context as Arelat, the Kingdom of Arles and Vienne, or Kingdom of Burgundy-Provence, was a realm established in 933 by the merger of the kingdoms of Upper and Lower Burgundy under King Rudolf II. It was incorporated into the Holy Roman Empire in 1033 and from then on was one of the empire's three constituent realms, together with the Kingdom of Germany and the Kingdom of Italy. By the mid-13th century at the latest, however, it had lost its concrete political relevance.
Charles of Provence or Charles II was the Carolingian King of Provence from 855 until his early death in 863.
The Kingdom of Upper Burgundy was a Frankish dominion established in 888 by the Welf king Rudolph I of Burgundy within the territory of former Middle Francia. It grew out of the Carolingian margraviate of Transjurane Burgundy southeast of the Jura Mountains together with the adjacent County of Burgundy (Franche-Comté) in the northwest. The adjective 'upper' refers to its location upstream in the Rhône river valley, as distinct from Lower Burgundy and also from the Duchy of Burgundy west of the Saône river. Upper Burgundy reunited with the Kingdom of Lower Burgundy in 933 to form the Kingdom of Burgundy, later known as Kingdom of Arles or Arelat.
Middle Francia was a short-lived Frankish kingdom which was created in 843 by the Treaty of Verdun after an intermittent civil war between the grandsons of Charlemagne resulted in division of the united empire. Middle Francia was allocated to emperor Lothair I, the eldest son and successor of emperor Louis the Pious. His realm contained the imperial cities of Aachen and Pavia, but lacked any geographic or cultural cohesion, which prevented it from surviving and forming a nucleus of a larger state, as was the case with West Francia and East Francia.
Ermengard of Italy was Queen of Provence as the spouse of King Boso. She was the second and only surviving child of Emperor Louis II. In her early life, she was betrothed to Constantine, the junior Byzantine emperor, but whether the marriage actually occurred or not is still debated among historians. In 871, Ermengard and her family were taken hostage by Adelchis of Benevento but were later freed. In 876, Ermengard married Boso, a nobleman with connections to the Carolingian dynasty, and became queen upon his accession to the throne of Provence in 879. After her husband's death in 887, she served as regent of the kingdom during the minority of her son Louis the Blind.
The Bosonids were a dynasty of Carolingian era dukes, counts, bishops and knights descended from Boso the Elder. Eventually they married into the Carolingian dynasty and produced kings and an emperor of the Frankish Empire.
Fulcrad was the count of Arles in the middle of the ninth century, who was given military command over the other counts of the Provençal country and took the title of duke. His recorded activity took place after the treaty of Verdun (843), when Provence lay in the south of the kingdom of Middle Francia ruled by the Emperor Lothair I. As the leading man in Provence he seems to have succeeded Warin.
The Treaty of Prüm, concluded on 19 September 855, was the second of the partition treaties of the Carolingian Empire. As Emperor Lothair I was approaching death, he divided his realm of Middle Francia among his three sons.
Agilmar was the Frankish archbishop of Vienne, in modern France, from 842 to his death. Before being elected archbishop, he was the abbot of the abbey of Saint-Claude. He was also the arch-chancellor of Emperor Lothair I from 835 to 843.
