Robert II (c. 972 – 20 July 1031), called the Pious () or the Wise (), was King of the Franks from 996 to 1031, the second from the Capetian dynasty. Crowned Junior King in 987, he assisted his father on military matters (notably during the two sieges of Laon, in 988 and 991). His solid education, provided by Gerbert of Aurillac (the future Pope Sylvester II) in Reims, allowed him to deal with religious questions of which he quickly became the guarantor (he headed the Council of Saint-Basle de Verzy in 991 and that of Chelles in 994). Continuing the political work of his father, after becoming sole ruler in 996, he managed to maintain the alliance with the Duchy of Normandy and the County of Anjou and thus was able to contain the ambitions of Count Odo II of Blois.
Robert II distinguished himself with an extraordinarily long reign for the time. His 35-year-long reign was marked by his attempts to expand the royal domain by any means, especially by his long struggle to gain the Duchy of Burgundy (which ended in 1014 with his victory) after the death in 1002 without male descendants of his paternal uncle Duke Henry I, after a war against Otto-William of Ivrea, Henry I's stepson and adopted by him as his heir. His policies earned him many enemies, including three of his sons.
The marital setbacks of Robert II (he married three times, having two of these annulled and attempting to have the third annulled, prevented only by the Pope's refusal to agree to a third annulment), strangely contrasted with the pious aura, bordering on holiness, which his biographer Helgaud of Fleury was willing to lend him in his work "Life of King Robert the Pious" (Epitoma vitæ regis Roberti pii). His life was then presented as a model to follow, made of innumerable pious donations to various religious establishments, of charity towards the poor and, above all, of gestures considered sacred, such as the healing of certain lepers. Robert II was the first sovereign considered to be a "miracle worker". The end of his reign revealed the relative weakness of the sovereign, who had to face the revolt of his third wife Constance and then of his own sons (Henri and Robert) between 1025 and 1031.

Youth and political formation
The only heir of the Duke of the Franks
Robert II's exact date and birthplace are unknown, although historians have advocated for the year 972 and the city of Orléans (the capital of the Robertians from the 9th century onward). The only son of Hugh Capet and Adelaide of Aquitaine, he was named after his heroic ancestor Robert the Strong, who had died fighting the Vikings in 866. His parents' marriage produced at least two other daughters: Hedwig (wife of Reginar IV, Count of Hainaut) and Gisela (wife of Hugh I, Count of Ponthieu).
In the 10th century, the Robertians were the most powerful aristocratic family in the Kingdom of France. In previous decades, two of its members, Odo (888) and Robert I (922), had ascended to the throne, displacing the ruling Carolingian dynasty. The principality of Hugh the Great, Duke of the Franks and Robert II's paternal grandfather, marked the apogee of the Robertians until his death in 956. In the middle of the 10th century, Hugh Capet succeeded as the head of the family.
Robert II's youth was especially marked by the incessant fights of King Lothair of France to recover Lorraine, the "cradle of the Carolingian family", at the expense of Emperor Otto II:
In August 978, King Lothair unexpectedly launched a general assault on Aix-la-Chapelle where the imperial family resided, which narrowly escaped capture. After having looted the imperial palace and the surroundings, he returned to France carrying the insignia of the Empire. In the following October, to take revenge, Otto II assembled an army of 60,000 men and invaded Lothair's domains. The latter, with only a few troops around him, was forced to take refuge with Hugh Capet, who was then said to be the savior of the Carolingian kingship. The Robertian dynasty then took a turn that changed the fate of young Robert II. Bishop Adalbero of Reims, originally a man of King Lothair, turns more and more towards the Ottonian court for which he feels a great sympathy.
