Count of Forcalquier in the context of "Ermengol IV of Urgell"

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.

Robert of Anjou (Italian: Roberto d'Angiò), known as Robert the Wise (Italian: Roberto il Saggio; 1276 – 20 January 1343), was King of Naples, titular King of Jerusalem and Count of Provence and Forcalquier from 1309 to 1343, the central figure of Italian politics of his time. He was the third son of King Charles II of Naples and Mary of Hungary, and during his father's lifetime he was styled Duke of Calabria (1296–1309).

Robert's early life was marked by his family's participation in the War of the Sicilian Vespers, in which conflict Robert served as a military commander. Upon the death of his father in 1309, Robert ruled as the king of Naples. His reign brought relative stability to Naples compared to the reigns of his father and grandfather, but it was also marked by rivalries against Germanic powers in northern Italy and the House of Barcelona in the western Mediterranean. Robert was pre-deceased by his son and heir Charles of Calabria, and so willed his throne to his granddaughter, Joanna of Naples.

Geoffrey II (also Josfred or Josfredus; died 13 February 1067) was the first count of Forcalquier following the death of his father Fulk Bertrand in 1062. His elder brother William Bertrand inherited Provence, but not the title of margrave. Geoffrey himself is often counted amongst the co-counts of Provence of the era. It is not certain that his region of Forcalquier was regarded as a distinct entity and not merely the Provençal demesne under his charge.

He subscribed a charter of his brothers on 14 February 1064. His wife was Ermengard, but his children are unknown.

William I (born c. 1085 and died October 1129) was the Count of Forcalquier and Marquis of Provence from 1094. He was the second son of Count Ermengol IV of Urgell and the only son of Adelaide of Forcalquier, heiress of Count William Bertrand of Provence.

William married Gersende, daughter of Count Guigues III of Albon. They had two sons, Guigues of Forcalquier and Bertrand I.

Ramon Berenguer IV or V (French: Raimond-Bérenger; 1198 – 19 August 1245) was a member of the House of Barcelona who ruled as count of Provence and Forcalquier. He was the first count of Provence to live in the county in more than one hundred years. During the minority of a previous count in 1144–1161, the regency was exercised by Ramon Berenguer IV de Barcelona, who is sometimes counted among the counts of Provence, which has led to varied numbering of the counts of Provence named Ramon Berenguer. This Ramon Berenguer was the fourth of his name to be a reigning count of Provence.
