Carolingians in the context of "Boso of Provence"

The counts of Nantes were originally the Frankish rulers of the Nantais under the Carolingians and eventually a capital city of the Duchy of Brittany. Their county served as a march against the Bretons of the Vannetais. Carolingian rulers would sometimes attack Brittany through the region of the Vannetais, making Nantes a strategic asset. In the mid-ninth century, the county finally fell to the Bretons and the title became a subsidiary title of the Breton rulers. The control of the title by the Breton dukes figured prominently in the history of the duchy. The County of Nantes was given to Hoel, a disinherited son of a duke. He lost the countship due to a popular uprising. That uprising presented an opportunity for King Henry II of England to attack the Breton duke. In the treaty ending their conflicts, the Breton duke awarded the county to Henry II.

The Capetian dynasty (/kəˈpiːʃən/ kə-PEE-shən; French: Capétiens/ka.pe.sjɛ̃/), also known as the House of France (French: La Maison de France), is a dynasty of Frankish origin, and a branch of the Robertians agnatically, and the Carolingians through female lines. It is among the largest and oldest royal houses in Europe and the world, and consists of Hugh Capet, the founder of the dynasty, and his male-line descendants, who ruled in France without interruption from 987 to 1792, and again from 1814 to 1848. The senior line from the House of Capet ruled in France from the election of Hugh Capet in 987 until the death of Charles IV in 1328. That line was succeeded by cadet branches, first the House of Valois, and succeeding them the House of Bourbon, which ruled until the French Revolution abolished the monarchy in 1792 and tried and executed King Louis XVI in 1793. The Bourbons were restored in 1814 in the aftermath of Napoleon's defeat, but had to vacate the throne again in 1830 in favor of the last Capetian monarch of France, Louis Philippe I, who belonged to the House of Orléans, a cadet branch of the Bourbons. Cadet branches of the Capetian House of Bourbon are still reigning over Spain and Luxembourg.

The dynasty had a crucial role in the formation of the French state. From a power base initially confined to their own demesne, the Île-de-France, the Capetian kings slowly but steadily increased their power and influence until it grew to cover the entirety of their realm. For a detailed narration on the growth of French royal power, see Crown lands of France. Members of the dynasty were traditionally Catholic, and the early Capetians had an alliance with the Church. The French were also the most active participants in the Crusades, culminating in a series of five Crusader kings – Louis VII, Philip Augustus, Louis VIII, Louis IX, and Philip III. The Capetian alliance with the papacy suffered a severe blow after the disaster of the Aragonese Crusade. Philip III's son and successor, Philip IV, arrested Pope Boniface VIII and brought the papacy under French control. The later Valois, starting with Francis I, ignored religious differences and allied with the Ottoman sultan to counter the growing power of the Holy Roman Empire. Henry IV was a Protestant at the time of his accession, but realized the necessity of conversion after four years of religious warfare.

The House of Welf (also Guelf or Guelph) is a European dynasty that has included many German and British monarchs from the 11th to 20th century and Emperor Ivan VI of Russia in the 18th century. The originally Franconian family from the Meuse-Moselle area was closely related to the imperial family of the Carolingians.

The Robertians (sometimes called the Robertines in modern scholarship) are a proposed Frankish noble family and royal dynasty, whose members were ancestors of the Capetian dynasty that ruled over the Kingdom of France and several other countries (currently Spain and Luxembourg). Prominent Robertian ancestors of the Capetian dynasty appear in historical records as powerful nobles serving under various rulers of the Carolingian dynasty, mainly in West Francia, which later became France. Most notable of them were: the eponymous count Robert the Strong (d. 866) and his sons, West Frankish kings Odo (888–898) and Robert I (922–923), whose son – duke Hugh the Great was father to the first Capetian king Hugh Capet (987–996).

Carloman II (c. 866 – 6 December 884) was the King of West Francia (future France) from 879 until his death. A member of the Carolingians, he and his elder brother Louis III, divided the kingdom between themselves and ruled jointly until the latter's death in 882. Thereafter Carloman ruled alone until his own death. He was the second son of King Louis the Stammerer and Queen Ansgarde.

Ekkehard of Aura (Latin: Ekkehardus Uraugiensis; born c. 1080, died 20 February 1126) was the first abbot of Aura from 1108. The monastery was founded by Bishop Otto of Bamberg on the Franconian Saale river, near Bad Kissingen, Bavaria. It is thought that Ekkehard was a member of the Bavarian aristocracy.

A Benedictine monk and chronicler, he made updates to the World Chronicle (Chronicon universale) of Frutolf of Michelsberg, adding important German history between 1098 and 1125 during the reign of Emperor Henry V, in which he sided strongly with the papacy in the Investiture Controversy. He was a participant in the Crusade of 1101 (Lerner, 1989), and provided important source material for the Rhineland massacres of Jews and for the First Crusade.
