Clovis I (; reconstructed Frankish: ; – 27 November 511) was the first Frankish king to unite the Franks, changing the form of leadership from a group of petty kings to rule by a single king, and ensuring that the kingship was passed down to his heirs. He is considered the founder of the Merovingian dynasty, which ruled the Frankish kingdom for the next two centuries. Clovis is an important figure in the history of France. According to Charles de Gaulle, he was "the first king of what would become France."

Clovis succeeded his father, Childeric I, as a king of the Salian Franks in 481, and eventually came to rule an area extending from what is now the southern Netherlands to northern France, corresponding in Roman terms to Gallia Belgica (northern Gaul). At the Battle of Soissons (486), he established control over a rump state of the fragmenting Western Roman Empire, which was under the command of Syagrius. By the time of his death in 511, Clovis had conquered several smaller Frankish kingdoms in the northeast of Gaul, stretching into what is now Germany. Clovis also conquered the Alemanni in eastern Gaul and the Visigothic kingdom of Aquitania in the southwest. These campaigns added significantly to his Frankish domains and established his dynasty as a major political and military presence in western Europe.

Clovis is also significant because of his baptism between 498 and 506, largely at the behest of his wife, Clotilde, who would later be venerated as a saint for this act, celebrated today in both the Catholic Church and Eastern Orthodox Church. The adoption of Catholicism (as opposed to the Arianism of most other Germanic tribes) by Clovis led to widespread conversions among the Franks, and eventually to religious unification across what is now modern-day France, the Low Countries and Germany. The alliance between the Franks and Catholicism eventually led to Charlemagne's crowning by the Pope as emperor in 800, and to the subsequent birth of the early Holy Roman Empire in the middle of the 10th century.

Name

Based on the attested forms, the Frankish name is generally reconstructed as *Hlodowig. The commonly accepted interpretation derives it from two Proto-Germanic elements,*hlūdaz ('loud, famous') and *wiganą ('to battle, to fight'), which underlies the traditional translation of Clovis's name as 'famous warrior' or 'renowned in battle'.

Linguist Reinder van der Meulen has questioned whether the traditional derivation from Proto-Germanic hlūd- ('famous') fully accounts for the vocalism found in the Merovingian forms. He notes that Gregory of Tours consistently writes Chlodo- with 'o', even though he uses 'u' elsewhere for names that etymologically contain u (e.g., Fredegundis, Guntchramnus, Arnulfus). On this basis, van der Meulen proposes that the first element might instead reflect a stem lod- ('to take booty, to plunder'), which would yield an interpretation of *Hlodowig as 'warrior for booty'. He further suggests that this interpretation would avoid the semantic redundancy that would occur in the name Chlodomer if both elements (traditionally analysed as hlūd- and -mērijaz, each meaning 'famous') were assumed to belong to the same semantic field.

In Middle Dutch, a language descended from Frankish, the name was rendered as Lodewijch (cf. modern Dutch Lodewijk). The name is found in other West Germanic languages, with cognates including Old English Hloðwig, Old Saxon Hluduco, and Old High German Hludwīg (variant Hluotwīg). The latter turned into Ludwig in Modern German, although the king Clovis himself is generally named Chlodwig. The Old Norse form Hlǫðvér was most likely borrowed from a West Germanic language.

The Frankish name *Hlodowig is at the origin of the French given name Louis (variant Ludovic), borne by 18 kings of France, via the Latinized form Hludovicus (variants Ludhovicus, Lodhuvicus, or Chlodovicus). The English Lewis stems from the Anglo-French Louis.

Background Clovis was the son of Childeric I, a king of the Salian Franks, and Basina, a Thuringian princess. The dynasty he founded is, however, named after Clovis' supposed grandfather, Merovech. Later legends created a genealogy that linked the Merovingians to the Trojan War.

Numerous small Frankish petty kingdoms existed by the 5th century. In the year 358, the Salian Franks was the first known Frankish tribe that settled with official Roman permission, at Toxandria (near the North Brabant province of the modern Netherlands). The Salian Franks lived by shores of the North Sea, while the Ripuarian Franks, a neighboring tribe, lived on the banks of the Rhine. Around 430, Chlodio attacked westwards from this area to take control of Tournai, then southwards to Artois, and Cambrai, eventually controlling an area stretching to the Somme river.

Childeric I, Clovis's father, was reputed to be a relative of Chlodio and was known as the king of the Franks who fought as an army within northern Gaul. In 463, he fought in conjunction with Aegidius, the magister militum of northern Gaul, to defeat the Visigoths in Orléans. Childeric died in 481 and Clovis succeeded him as king, aged just 15. Historians believe that Childeric and Clovis were both commanders of the Roman military in the province of Belgica Secunda, and were subordinate to the magister militum. The Franks of Tournai came to dominate their neighbours, initially aided by the association with Aegidius.

The death of Aetius in 454 led to the decline of imperial power in Gaul, leaving the Visigoths and the Burgundians competing for predominance in the area. The Western Roman Empire was reduced Italy and a few territories, and imperial rule in the West finally ended with the deposition of Romulus Augustulus in 476. The parts of Gaul controlled Syagrius, Aegidius's son, became what is now known as the Kingdom of Soissons.

Though no primary sources expounding on the language spoken by Clovis exist, historical linguists consider it likely that, based on his family history and core territories, he spoke a form of Old Dutch. In this, the early Merovingians can be contrasted with the later Carolingians, such as Charlemagne, of the late 8th century and onward, who probably spoke various forms of Old High German.Einhard, Vita Karoli 25. & Janet Nelson: King and Emperor. London 2019, pp. 68.

Early reign (481–491) Road to Soissons

In 486, Clovis began his efforts to expand the realm by allying himself with his relative Ragnachar, king of Cambrai and another Frankish king, Chararic. These rulers are sometimes referred to as regulus (diminutive of rex). Together the triumvirate marched against Syagrius and met the Gallo-Roman commander at Soissons. During the battle, Chararic betrayed his comrades by refusing to take part in the fighting. Despite the betrayal, the Franks landed a decisive victory, forcing Syagrius to flee to the court of Alaric II. This battle is viewed as bringing about the end of the rump state of the Western Roman Empire outside of Italy. Following the battle, Clovis invaded the traitor Chararic's territory and was able to imprison him and his son.

Uniting Gaul

Prior to the battle, Clovis did not enjoy the support of the Gallo-Roman clergy, so he proceeded to pillage the Roman territory, including the churches. The Bishop of Reims requested Clovis return everything taken from the Church of Reims; the young king aspired to establish cordial relationships with the clergy, so he returned a valuable ewer taken from the church. Despite his position, some Roman cities refused to yield to the Franks, namely Verdun ‒ which surrendered after a brief siege ‒ and Paris, which stubbornly resisted for a few years, perhaps as many as five. He made Paris his capital and established an abbey dedicated to Saints Peter and Paul on the south bank of the Seine.

Realizing that he would not be able to rule Gaul without the help of the clergy, Clovis took a Catholic wife to please them. He also integrated many of Syagrius's units into his own army. The Roman kingdom was probably under Clovis's control by 491 because in the same year, Clovis allegedly moved against a small number of Thuringians in eastern Gaul, near the Burgundian border.

Middle reign (492–506) Barbarian Relations

Around 493 AD, he secured an alliance with the Ostrogoths through the marriage of his sister Audofleda to their king, Theodoric the Great. In the same year, the neighboring King of the Burgundians was slain by his brother, Gundobad; bringing civil strife to that kingdom. Allegedly, Gundobad proceeded to drown his sister-in-law and force his niece, Chrona, into a convent. Another niece, Clotilde, fled to the court of the third brother, Godegisel. Finding himself in a precarious position, Godegisel decided to ally himself to Clovis by marrying his exiled niece to the Frankish king.

Assault of the Alamanni

In 496, the Alamanni invaded and some Salians and Ripuarians reguli (kings) defected to their side. Clovis met his enemies near the strong fort of Tolbiac. During the fighting, the Franks suffered heavy losses. Clovis, together with over three thousand Frankish companions, may have converted to Christianity around this time. With the help of the Ripuarian Franks he narrowly defeated the Alamanni in the Battle of Tolbiac in 496. Now Christian, Clovis confined his prisoners, Chararic and his son, to a monastery.

Relations with Burgundy

In 500 or 501, Godegisel began scheming against his brother Gundobad. He promised his brother-in-law territory and annual tribute for defeating his brother. Clovis was eager to subdue the political threat to his realm and crossed into the Burgundian territory. Gundobad then moved against Clovis and called his brother for reinforcements. The three armies met near Dijon, where both the Franks and Godegisel's forces defeated the dumbfounded Gundobad, who escaped to Avignon. Clovis pursued him and laid siege to the city. After some months, Clovis was convinced to abandon the siege and settled for an annual tribute from Gundobad.

Armorici allies In 501, 502 or 503, Clovis led his troops to Armorica. He had previously restricted his operations to minor raids, but now the goal was subjugation. Clovis failed to complete this objective via military means; therefore, he was constrained to statecraft. This proved fruitful, for the Armonici shared Clovis's disdain for the Arian Visigoths. Armorica and its fighters were thus integrated into the Frankish realm.

Late reign (507–511)

Relations with the Visigoths

In 507 Clovis was allowed by the magnates of his realm to invade the remaining threat of the Kingdom of the Visigoths. King Alaric had previously tried to establish a cordial relationship with Clovis by serving him the head of exiled Syagrius on a silver plate in 486 or 487. However, Clovis was no longer able to resist the temptation to move against the Visigoths, for many Catholics under Visigoth yoke were unhappy and implored Clovis to make a move. But just to be absolutely certain about retaining the loyalties of the Christians under Visigoths, Clovis ordered his troops to omit raiding and plunder, for this was not a foreign invasion, but a liberation.

The Visigothic Kingdom of Toulouse was defeated at the Battle of Vouillé in 507, resuting in the death of Visigothic king Alaric II and the end of Visigothic power in Gaul. According to Gregory of Tours, following the battle the Byzantine Emperor Anastasius I made Clovis a patrician and honorary consul.
