Clovis I

Lore & Background

In 511, Chlothar I and his three brothers — Theuderic, Chlodomer, and Childebert — inherited their shares of their father's kingdom. Chlothar spent most of his life in a campaign to expand his territories at the expense of his relatives and neighbouring realms in all directions. His brothers avoided outright war by cooperating with Chlothar's attacks on neighbouring lands in concert or by invading lands when their rulers died. The spoils were shared between the participating brothers. By the end of his life, Chlothar had managed to reunite Francia by surviving his brothers and seizing their territories after they died. But upon his own death, the Kingdom of the Franks was once again divided between his own four surviving sons. A fifth son had rebelled and was killed, along with his family. Chlothar's father, Clovis I, had converted to Nicene Christianity, but Chlothar, like other Merovingians, did not consider that the Christian doctrine of monogamy should be expected of royalty: he had five wives, more from political expediency, for the purpose of forming alliances, than for personal motives. Frankish customs of the day allowed for the practice of polygamy, especially among royalty. Under Salic law, Clovis I instituted the custom of sons being the primary heirs in all respects, but the inheritance was split evenly between all the sons, so the greater Frankish Kingdom was often splintered into smaller sub-kingdoms.

Reader's Guide

Chlothar I is a key figure in Merovingian history for reuniting the Frankish kingdom after decades of division. His strategy of cooperating with his brothers on external campaigns while waiting for them to die allowed him to absorb their territories without fratricidal war. His marital alliances were central to his political expansion: he married Guntheuc, widow of his brother Chlodomer, to gain access to Chlodomer's treasury; Radegund, daughter of the Thuringian king, to consolidate dominance over Thuringia; and Ingund, by whom he had five sons and two daughters. He also married Ingund's sister Aregund and later Chunsina, mother of his rebellious son Chram. Despite his successes, the Merovingian system of equal inheritance among sons meant that his reunification was temporary — upon his death, the kingdom was again divided among his four surviving sons.

• He married his brother Chlodomer's widow, Guntheuc, to gain access to Chlodomer's treasury.
• His wife Radegund, daughter of the Thuringian king, was later canonized as a saint after retiring to a convent and founding the first nunnery in Europe.
• A ninth-century forged genealogy invented a daughter of Chlothar named Blithilde to connect the Merovingian and Carolingian dynasties.
• Chlothar imposed taxes on ecclesiastical property despite funding new churches at his queens' urging.

The Long Game of Reunification

In 511, the young Chlothar inherited his portion of the Frankish realm alongside three brothers — Theuderic, Chlodomer, and Childebert — splitting the territory their father Clovis had built. Rather than accepting his allotted share as permanent, Chlothar devoted the remainder of his life to a relentless campaign of territorial expansion, pressing against relatives and neighbouring kingdoms on every front. His brothers, wary of direct fratricidal conflict, chose cooperation over confrontation: they joined his offensives against external lands or moved in when a neighbouring ruler died, dividing the spoils among all participants. This arrangement kept them from fighting one another while still allowing Chlothar's ambitions to drive the expansion. The strategy ultimately succeeded. Outliving his three brothers, Chlothar absorbed their territories one by one, reuniting Francia under a single crown for the first time since Clovis's death. Yet the achievement proved fragile. When Chlothar himself died around December 561, the kingdom was once again parcelled out among his four surviving sons, while a fifth — who had raised a rebellion — was put to death along with his household.

Five Wives, Five Alliances

Chlothar's marital history reads less like a love story and more like a diplomatic ledger. Frankish royal custom of the era permitted — indeed encouraged — polygamy, a sharp break from the monogamous norms the Church had inherited from late Roman practice. Chlothar took five wives, each serving a distinct political purpose. His first union, around 524, was with Guntheuc, the widow of his late brother Chlodomer; the marriage granted him access to Chlodomer's treasury and secured Guntheuc's position as sole heiress to the lands of King Godegisel. Around 532 he wed Radegund, daughter of the Thuringian king Bertachar, a match that consolidated his authority over Thuringia. His third marriage, to Ingund, proved the most prolific, producing five sons and two daughters. He then married Ingund's own sister Aregund — reportedly at Ingund's request when no other suitor seemed worthy — and finally Chunsina, mother of the rebellious Chram. A possible marriage to Waldrada, later repudiated, adds a further footnote to this web of alliances.

A Kingdom Divided by Design

The Merovingian succession system was, by its very structure, a recipe for fragmentation. Under the Germanic traditions that predated Frankish kingship, inheritance flowed laterally — to younger brothers, uncles, and cousins — rather than vertically to sons. Clovis I, Chlothar's father, had shifted the emphasis: through Salic law he made sons the primary heirs in all respects. Yet this was emphatically not primogeniture. There was no eldest son receiving the lion's share. Instead, the realm was split evenly among all surviving sons, guaranteeing that every generation would fracture the kingdom into smaller sub-kingdoms. Chlothar's own life illustrated the paradox. He spent decades reunifying Francia, only to see it shattered again at his death among four heirs. The system also shaped personal life. Although Clovis had converted to Nicene Christianity, Chlothar and his fellow Merovingians saw no obligation to adopt the Church's doctrine of monogamy. Multiple wives and competing heirs were not scandal but standard operating procedure for a dynasty that needed to hold together a vast, diverse territory without the administrative machinery Rome had once provided.

Shadows on the Lineage

Chlothar's legacy extends well beyond the political map he redrew. His name, meaning 'glory' in the old tongue, was carried by a dynasty whose later rulers would struggle to justify their authority. In the ninth century, during the reign of Charles the Bald, a forged genealogy appeared in the so-called Brabant trophies. This document invented a daughter of Chlothar named Blithilde, who supposedly married the saint and bishop Ansbert of Rouen. From that union, it claimed, was born the Duke Arnoald, father of Arnulf of Metz. The fabrication served a clear purpose: it stitched the Merovingian and Carolingian dynasties together, creating the appearance that the Carolingians held the throne by hereditary right rather than by conquest or papal favour. It also linked them to the Romans through the senatorial family Ferreoli, lending an air of ancient legitimacy. Meanwhile, Chlothar's own relationship with the Church remained ambivalent. At his queens' urging he funded new ecclesiastical buildings, yet he remained a lukewarm Christian and managed to impose taxes on church property — a reminder that even a king who built churches could still squeeze them for coin.
