Count of Provence in the context of "Robert the Wise"

Charles I (Italian: Carlo; early 1226/1227 – 7 January 1285), commonly called Charles of Anjou or Charles d'Anjou, was King of Sicily from 1266 to 1285. He was a member of the Capetian dynasty and the founder of the House of Anjou-Sicily. Between 1246 and 1285, he was Count of Provence and Forcalquier in the Holy Roman Empire and Count of Anjou and Maine in France. In 1272 he was proclaimed King of Albania, in 1277 he purchased a claim to the Kingdom of Jerusalem, and in 1278 he became Prince of Achaea after the previous ruler, William of Villehardouin, died without heirs.

The youngest son of Louis VIII of France and Blanche of Castile, Charles was destined for a church career until the early 1240s. He acquired Provence and Forcalquier through his marriage to Beatrice. His attempts to restore central authority brought him into conflict with his mother-in-law, Beatrice of Savoy, and the nobility. He relinquished control of Forcalquier to his mother-in-law in 1248, although she returned it to him in 1256. Charles received Anjou and Maine from his brother, Louis IX of France, in appanage. He accompanied Louis during the Seventh Crusade to Egypt. Shortly after he returned to Provence in 1250, Charles forced three wealthy autonomous cities—Marseille, Arles and Avignon—to acknowledge his suzerainty.

Louis I (Italian: Luigi, Aloisio, or Ludovico ; 1320 – 26 May 1362), also known as Louis of Taranto, was a member of the Capetian House of Anjou who reigned as King of Naples, Count of Provence and Forcalquier, and Prince of Taranto.

Louis gained the crown of Naples by marrying his half-first cousin/ first cousin-once-removed, Queen Joanna I, whose prior husband, Andrew, had died as a result of a conspiracy that may have involved both of them. Immediately after securing his status as her co-ruler, Louis successfully wrested away all power from his wife, leaving her a sovereign in name only. Their disastrous marriage resulted in the birth of two daughters, Catherine and Frances, neither of whom survived their parents. During their joint reign, Louis dealt with numerous uprisings, attacks, and unsuccessful military operations; he is generally considered an inefficient monarch. Following his death, Joanna resumed her power and refused to share it with her subsequent husbands.

Louis XVIII (Louis Stanislas Xavier; 17 November 1755 – 16 September 1824), known as the Desired (French: le Désiré), was King of France from 1814 to 1824, except for a brief interruption during the Hundred Days in 1815. Before his reign, he spent 23 years in exile from France beginning in 1791, during the French Revolution and the First French Empire.

Until his accession to the throne of France, he held the title of Count of Provence as brother of King Louis XVI, the last king of the Ancien Régime. On 21 September 1792, the National Convention abolished the monarchy and deposed Louis XVI, who was later executed by guillotine. When his young nephew Louis XVII died in prison in June 1795, the Count of Provence claimed the throne as Louis XVIII.

The County of Forcalquier was a large medieval county in the region of Provence in the Kingdom of Arles, then part of the Holy Roman Empire. It was named after the fortress around which it grew, Forcalquier.

The earliest mention of a castle at Forcalquier dates to 1044, when it was in the possession of Fulk Bertrand, joint count of Provence. When Fulk died in 1051 his lands were shared between his sons William Bertrand and Geoffrey II, who inherited Forcalquier. Sometime in the 1060s Forcalquier was inherited by William's daughter Adelaide, who was the first person to be styled "Countess of Forcalquier". She married Ermengol IV of Urgell and died in 1129, at a time when Provence was sharply disputed by the many persons who had inherited some title to it. The counts of Toulouse claimed the title marchio as descendants of Emma of Provence, while the counts of Barcelona laid claim to Provence as descendants of Douce I. In 1125 a formal division of Provence into a march and a county was effected, but in 1131 a new claimant, the House of Baux, provoked a series of wars, the Baussenque Wars, fought over the rights to the county of Provence. Meanwhile, the county north of the Durance, with Forcalquier and Embrun, had devolved to Adelaide's son by Ermengol, William III (the enumeration of counts of Forcalquier includes earlier counts of Provence). William III and his descendants, a cadet branch of the counts of Urgell, continued to rule Forcalquier until the end of the century, when the Treaty of Aix (1193) gave in marriage the last count's granddaughter, Garsenda of Sabran, to Alfonso, son of Alfonso II of Aragon and heir of the county of Provence. Their marriage in July 1193, Alfonso's inheritance in 1196, and Garsenda's in 1209 united the two counties permanently.

Charles II, also known as Charles the Lame (French: Charles le Boiteux; Italian: Carlo lo Zoppo; 1254 – 5 May 1309), was King of Naples, Count of Provence and Forcalquier (1285–1309), Prince of Achaea (1285–1289), and Count of Anjou and Maine (1285–1290); he also was King of Albania (1285–1294), and claimed the Kingdom of Jerusalem from 1285. He was the son of Charles I of Anjou—one of the most powerful European monarchs in the second half of the 13th century—and Beatrice of Provence. His father granted Charles the Principality of Salerno in the Kingdom of Sicily (or Regno) in 1272 and made him regent in Provence and Forcalquier in 1279.

After the uprising known as the Sicilian Vespers against Charles's father, the island of Sicily became an independent kingdom under the rule of Peter III of Aragon in 1282. A year later, his father made Charles regent in the mainland territories of the Regno (or the Kingdom of Naples). Charles held a general assembly where unpopular taxes were abolished and the liberties of the noblemen and clerics were confirmed. He could not prevent the Aragonese from occupying Calabria and the islands in the Gulf of Naples. The Sicilian admiral Roger of Lauria captured him in a naval battle near Naples in 1284. As he was still in prison when his father died on 7 January 1285, his realms were ruled by regents. The remainder of his rule was spent seeking a resolution to the Sicilian war, diplomatic moves concerning his inheritance, and administrating the new Kingdom of Naples.

René I of Anjou (Italian: Renato; Occitan: Rainièr; 16 January 1409 – 10 July 1480) was Duke of Anjou and Count of Provence from 1434 to 1480, who also reigned as King of Naples from 1435 to 1442 (then deposed). Having spent his last years in Aix-en-Provence, he is known in France as the Good King René (Occitan: Rei Rainièr lo Bòn; French: Le bon roi René).

René was a member of the House of Valois-Anjou, a cadet branch of the French royal house, and the great-grandson of John II of France. He was a prince of the blood, and for most of his adult life also the brother-in-law of the reigning king Charles VII of France. Other than the aforementioned titles, he was also Duke of Bar from the 1420s onwards and Duke of Lorraine from 1431 to 1453.
