Hugh of Provence abdicates the throne in favor of his son Lothair II who is acclaimed sole king of Italy.

The early 10th century in Europe was a tumultuous period, particularly within the fragmented territories that once comprised the mighty Carolingian Empire. Amidst this complex tapestry of emerging kingdoms and ambitious aristocrats, two figures, father and son, held the often-precarious title of King of Italy: Hugh of Arles and Lothair II.

Hugh of Arles: The Ambitious King of Italy (926–947)

Known variously as Hugh of Arles or Hugh of Provence, Hugh (c. 880–947) emerged as a significant power player in the fractured landscape of the former Carolingian realm. A prominent member of the Bosonid family, a powerful Frankish dynasty with extensive influence in regions like Provence and Burgundy, Hugh ascended to the throne of Italy in 926. This was a time when the "Kingdom of Italy" (often referred to as the Regnum Italicum) was less a cohesive state and more a contested prize, frequently changing hands among powerful local magnates.

During his two-decade reign, Hugh pursued a deliberate strategy to consolidate his authority. A hallmark of his rule was the systematic empowerment of his own relatives, installing them in key positions and granting them considerable influence, often at the direct expense of the established Italian aristocracy. While this created a loyal power base, it inevitably alienated many powerful noble families, sowing seeds of future dissent.

On the international stage, Hugh cast his gaze southward, seeking to forge connections with the formidable Byzantine Empire. Such an alliance could have offered prestige, potential military support against various threats, and a degree of legitimacy in a continent where the memory of Roman imperial power still resonated through Constantinople. Domestically, Hugh proved adept at defending his realm from external enemies, which during this era often included the marauding Magyars from the east and Saracen raiders from the south. However, despite these successes, his internal policies and personal conduct—often described as creating "domestic habits" that bred opposition—generated numerous internal foes. The growing discontent among the Italian nobility eventually led to his removal from power in 945, though he died two years later.

Lothair II: The King in Name Only (947–950)

Following his father's forced retreat, Lothair II (926/8 – 22 November 950), also known as Lothair of Arles, inherited the nominal title of King of Italy. Like his father, Lothair was a scion of the noble Frankish Bosonid lineage, tracing his ancestry back to Boso the Elder. His mother was a German princess named Alda (sometimes recorded as Hilda), further cementing his connections to the broader European aristocracy.

Despite holding the coveted title of rex Italiae, Lothair's reign was characterized by a profound lack of actual authority. He was king in name only. From 945 onwards, following a successful uprising of the Italian nobles that effectively sidelined Hugh, the real power in Italy lay firmly in the hands of Berengar of Ivrea, a powerful and ambitious margrave. Berengar controlled all significant patronage and governance, leaving Lothair as a mere figurehead.

A Strategic Marriage and Political Landscape

Lothair's marriage was a pivotal moment in his brief public life, arranged as part of a complex political settlement. Betrothed in 931, he finally married on December 12, 947, to the remarkable fifteen-year-old Adelaide, daughter of Rudolph II of Burgundy and Bertha of Swabia. This union was designed to cement peace between the warring houses of Hugh of Arles and Rudolph II of Burgundy. In a significant earlier development in 933, Hugh had ceded his own Kingdom of Provence to his long-standing rival, Rudolph II. Rudolph then merged this territory with his own domains, forming a new, influential Kingdom of Burgundy (often referred to as the Kingdom of Arles), though he himself died just four years later in 937.

Lothair and Adelaide's marriage produced a daughter, Emma, born around 948. Emma would later marry the Carolingian Lothair of France in 966, further illustrating the intricate web of dynastic alliances that characterized the era.

Death and Legacy: The Rise of Berengar and Adelaide's Resolve

Lothair's nominal reign was tragically cut short. He died at Turin on November 22, 950, at a young age. Contemporary accounts, and later historical interpretations, strongly suggest that his death was not natural; he was likely poisoned by the powerful Berengar of Ivrea. Berengar's motive was clear: to cement his usurped political power in Lombardy by forcing Lothair's young widow, Adelaide, to marry his own son, Adalbert. Such a marriage would have provided Berengar with a crucial claim to legitimate authority over the Italian throne.

However, Adelaide, described as spirited and intelligent, resolutely refused Berengar's demands. Instead, demonstrating remarkable courage and political acumen for her age, she sought the protection of the powerful Otto I of Germany. This plea would prove to be a turning point in Italian and European history, as Otto I subsequently invaded Italy, defeated Berengar, and eventually married Adelaide himself, initiating a new era of direct German involvement in Italian affairs that would culminate in the establishment of the Holy Roman Empire.

Lothair II, though a king largely without power, figures briefly but importantly in the historical record, notably in the vita (life) of his tenacious wife, Adelaide, penned by the illustrious German canoness, dramatist, and poet Hroswitha of Gandersheim.
