Charles the Bald vs Robert II the Pious

Charles the Bald, along with his brothers Lothair and Louis the German, signed the Treaty of Verdun, dividing the Carolingian Empire into three kingdoms. Charles received West Francia, which became the foundation of modern France.

Charles faced repeated Viking invasions, including the siege of Paris in 845. He paid large tributes (Danegeld) to buy off attackers, a strategy that temporarily secured peace but drained royal resources and exposed military weakness.

Pope John VIII crowned Charles the Bald as Holy Roman Emperor, following the death of Louis II. This coronation asserted Charles's claim to imperial authority but was contested by other Carolingian rulers.

Robert II succeeded his father Hugh Capet as King of the Franks. His reign was marked by efforts to consolidate royal power, but he faced challenges from powerful nobles and the Church, limiting his authority.

Robert II was excommunicated by Pope Gregory V for marrying Bertha of Burgundy, his cousin, without papal dispensation. The excommunication was lifted after Robert repudiated Bertha, but it damaged his reputation and strained relations with the Church.

Robert II supported the Cluniac monastic reforms, which aimed to purify the Church and reduce secular influence. His patronage strengthened the Cluniac movement and enhanced the Church's moral authority in France.

Robert II attempted to assert control over the Duchy of Burgundy after the death of Duke Henry I. The conflict lasted several years and resulted in limited success, as Burgundy remained largely independent under its own dukes.
