Louis the Pious in the context of "West Francia"

The Carolingian Empire (800–887) was a Frankish-dominated empire in Western and Central Europe during the Early Middle Ages. It was ruled by the Carolingian dynasty, which had ruled as kings of the Franks since 751 and as kings of the Lombards in Italy from 774. In 800 Pope Leo III crowned King Charlemagne as Roman emperor in return for political protection, disregarding the universalist claims of the weakened Byzantine Empire. The Carolingian Empire is sometimes considered the first phase in the history of the Holy Roman Empire.

After a civil war from 840 to 843 following the death of Emperor Louis the Pious, the empire was divided into autonomous kingdoms, with one king still recognised as emperor but with little authority outside his own kingdom. The unity of the empire and the hereditary right of the Carolingians continued to be acknowledged. In 884 Charles the Fat reunited all the Carolingian kingdoms for the last time, but he was deposed by the Frankish nobility in 887 and died in 888, and the empire immediately fractured. With the only remaining legitimate male of the dynasty a child, the nobility elected regional kings from outside the dynasty or, in the case of the eastern kingdom, an illegitimate Carolingian. The illegitimate line continued to rule in the east until 911, while in the western kingdom the legitimate Carolingian dynasty was restored in 898 and ruled until 987 with an interruption from 922 to 936.

Bulgarian Battle of Versinikia (Bulgarian: Битката при Версиникия; Greek: Μάχη της Βερσινικίας) was a battle fought in 813 AD between the Byzantine Empire and the Bulgarian Empire, near the city of Adrianople (Edirne), in modern-day Turkey.

The Bulgarian army, led by Krum of Bulgaria, defeated the Byzantine forces. Following this defeat, Michael I Rangabe abdicated, with Leo V the Armenian taking the Byzantine throne. The battle further strengthened Bulgarian control in the region after their victory over Nikephoros I two years earlier. After the battle, the Bulgarians controlled the whole region of Eastern Thrace (until the Byzantine–Bulgarian Treaty of 815), with the exception of a few castles that remained in Byzantine control. Krum died on 13 April 814, but his muster of "5,000 iron-plated wagons [ . . . ] to carry the siege equipment" alarmed the Byzantine court to such an effect that they asked for the aid of the Carolingian Emperor Louis the Pious. These large-scale military preparations were Krum's attempt to avenge his failure at the Second Bulgarian Siege of Constantinople one year prior.

The Treaty of Verdun (French: Traité de Verdun; German: Vertrag von Verdun), agreed to on 10 August 843, ended the Carolingian civil war and divided the Carolingian Empire between Lothair I, Louis II and Charles II, the surviving sons of the emperor Louis I. The treaty 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.

The treaty was the first of the four partition treaties of the Carolingian Empire, followed by the Treaties of Prüm (855), Meerssen (870), and Ribemont (880).

Charles the Bald (French: Charles le Chauve; 13 June 823 – 6 October 877), also known as Charles II of West Francia, was a 9th-century king of West Francia (843–77), King of Italy (875–77) and emperor of the Carolingian Empire (875–77). After a series of civil wars during the reign of his father, Louis the Pious, Charles succeeded, by the Treaty of Verdun (843), in acquiring the western third of the empire. He was a grandson of Charlemagne and the youngest son of Louis the Pious by his second wife, Judith.

The Carolingian Renaissance was the first of three medieval renaissances, a period of cultural activity in the Carolingian Empire. Charlemagne's reign led to an intellectual revival beginning in the 8th century and continuing throughout the 9th century, taking inspiration from ancient Roman and Greek culture and the Christian Roman Empire of the 4th century. The period saw an increase of literature, writing, visual arts, architecture, music, jurisprudence, liturgical reforms, and scriptural studies. Carolingian schools were effective centers of education, and they served generations of scholars by producing editions and copies of the classics, both Christian and pagan.

The movement occurred mostly during the reigns of Carolingian rulers Charlemagne and Louis the Pious. It was supported by the scholars of the court, notably Alcuin of York. Charlemagne's Admonitio generalis (789) and Epistola de litteris colendis served as manifestos. Alcuin wrote on subjects ranging from grammar and biblical exegesis to arithmetic and astronomy. He also collected rare books, which formed the nucleus of the library at York Cathedral. His enthusiasm for learning made him an effective teacher. Alcuin writes:

The Heliand (/ˈhɛliənd/) is an epic alliterative verse poem in Old Saxon, written in the first half of the 9th century. The title means "savior" in Old Saxon (cf. German and Dutch Heiland meaning "savior"), and the poem is a Biblical paraphrase that recounts the life of Jesus in the alliterative verse style of a Germanic epic. Heliand is the largest known work of written Old Saxon.

The poem must have been relatively popular and widespread because it exists in two manuscript versions and four fragmentary versions. It takes up about 6,000 lines. A praefatio exists, which could have been commissioned by either Louis the Pious (king from 814 to 840) or Louis the German (806–876). This praefatio was first printed by Matthias Flacius in 1562, and while it has no authority in the manuscripts it is generally deemed to be authentic. The first mention of the poem itself in modern times occurred when Franciscus Junius (the younger) transcribed a fragment in 1587. It was not printed until 1705, by the English clergyman George Hickes. The first modern edition of the poem was published in 1830 by Johann Andreas Schmeller.

The Carolingian civil war was a violent crisis over the succession to the Carolingian Empire following the death of Emperor Louis the Pious in June 840 and lasting until the Treaty of Verdun in August 843. Louis's eldest son, the emperor Lothar I, laid claim to an undivided empire, while his younger brothers Louis the German and Charles the Bald sought large kingdoms of their own on the basis of previous divisions planned by the late emperor. Their nephew, Pippin II, laid claim to Aquitaine.

After Louis the Pious's death, Lothar moved immediately to disregard the division of the empire and secure for himself his father's imperial position. He reached out to Pippin in Aquitaine for support against Charles. Not content with Bavaria alone, Louis the German occupied the Rhineland laying claim to all of Germania. The first military move of the budding civil war was Lothar's campaign that forced Louis from the Rhineland in August. It increased Lothar's prestige in the east, but ended in an armistice. Lothar then marched to the Seine in September, laying claim to Neustria, before reaching a truce with Charles.

Occitania is the historical region in southern Europe where the Occitan language was historically spoken and where it persists today as a local dialect. This cultural area roughly encompasses much of the southern third of France (except the French Basque Country and French Catalonia) as well as part of Spain (Aran Valley), Monaco, and parts of Italy (Occitan Valleys).

Occitania has been recognized as a linguistic and cultural concept since the Middle Ages. The territory was united in Roman times as the Seven Provinces (Latin: Septem Provinciae) and in the Early Middle Ages (Aquitanica or the Visigothic Kingdom of Toulouse, or the share of Louis the Pious following Thionville divisio regnorum in 806).
