Title: Richard III of Capua
Content:  Richard III (died 10 June 1120) was count of Aversa and prince of Capua briefly in 1120 between his anointing on 27 May and his death; he was the only son and heir of Robert I of Capua. He was an infant when his father died, and he fell under the regency of his uncle, Jordan. Richard III died within a few months and, though no contemporary chronicler blames him, some modern historians have cast doubt on Jordan's innocence. Jordan did succeed unopposed to the diminished Capuan throne.
Title: Richard II of Capua
Content:  Richard II (died 1105/06), called the Bald, was the count of Aversa and the prince of Capua from 1090 or 1091. He was under the guardianship of Count Robert of Caiazzo until he came of age in 1093. The eldest son and successor of Jordan I of Capua and Gaitelgrima, daughter of Prince Guaimar IV of Salerno, he was named after his grandfather, Richard I of Capua. While digressing on this impressive lineage, the chronicler William of Apulia in his The Deeds of Robert Guiscard says that he "though now only a young man, already shows courage worthy of an adult." He succeeded to his father's dominions at a very young age and immediately he and his family were thrown 
Title: Principality of Capua
Content:  In 1058, a year after the death of Pandulf's weak successor, the Norman count Richard of Aversa conquered Capua, but left the city itself in the control of Landulf VIII for another four years. Richard immediately increased his prestige with the princely title and his power by the territory which came under his authority. He became a neighbour of the popes and was both their protector and supporter and also an enemy who spent his last years in excommunication, as did his son and successor, Jordan I, who carved out a chunk of papal territory for the principality. At Richard's death, his family, the Drengot, had a prestige and power to match that of the Hauteville family, but they acted in a different sphere of influence: the Papal States and central Italy primarily. 
Title: List of Princes of Capua
Content: 1058–1078 Richard I ; 1078–1091 Jordan I ; 1091–1106 Richard II ; 1092–1098 Lando IV, held Capua in opposition to Richard II ; 1106–1120 Robert I ; 1120 Richard III ; 1120–1127 Jordan II ; 1127–1156 Robert II ; 1135–1144 Alfonso, son of Roger II ; 1144–1154 William, son of Roger II 1155–1158 Robert (III) ; 1166–1172 Henry These princes were of the Drengot line and served as a counterpoise to the House of Hauteville until it had finally lost all power. The chronology here, too, can be very confusing due to the rivalry between the Robert II and Roger II of Sicily and his sons.  To the Kingdom of Sicily, where it became an appanage for second sons: 
Title: Robert (son of William I of Sicily)
Content:  Robert (1153/4–1159/60) was the second son of King William I of Sicily and his queen, Margaret of Navarre. He was about four or five years old when he was appointed Prince of Capua in 1157 or 1158. Prior to his accession, since 1144, his father had been Prince of Capua. Robert's Latin title, princeps Capuanorum, means literally "Prince of Capuans". He was the third Robert of Capua, after Robert I and Robert II. The latter, who had been deposed in 1135, returned in 1155–56 in an effort to reclaim his principality. He managed to control some territory, but was ultimately unsuccessful. The young Robert's rule in Capua can be traced in documents between September 1158 and May 1159, but he had died by February–March 1160, when his father was once again ruling Capua directly. Eventually, Robert's younger brother Henry was appointed Prince of Capua in May 1166.
Title: Landulf VIII of Capua
Content:  Landulf VIII was the last Lombard prince of Capua from 1057, when his brother Pandulf VI died, to the conquest of the city in 1058 by Count Richard of Aversa. Landulf was first associated with the rule along with his brother in 1047, when their father, the infamous Pandulf IV, was reinstated as prince for the second time. According to the Catalogus Principum Capuæ, he reigned for twelve years, which would correspond to his rule jointly with his brother from their father's death in 1050 until his final expulsion from Capua. According to the Annali di Napoli, the city of Capua itself was not fully captured by Richard until 21 May 1062. Landulf was probably forced to surrender the keys to the city to Richard and his son Jordan in 1058, but allowed to continue ruling until 1062. Landulf's sons did not fare well. They were seen by Pope Victor III wandering the countryside of the Mezzogiorno as beggars.
Title: Richard I of Capua
Content:  internal strife and Emperor Henry III leaving a child heir, gave the Normans a near free hand in Southern Italy. Richard had been constantly seeking territorial expansion through war against his Lombard neighbors, Pandulf VI of Capua and Guaimar's son and successor, Gisulf II of Salerno. He pushed back the borders of the latter until there was little left of the once great principality but the city of Salerno itself and when the weak prince of Capua died in 1057, he immediately besieged Capua and took the princely title (1058) from Pandulf's brother, Landulf VIII, but left the keys to the city in Lombard hands for at least four years more, until 12 May 1062.
Title: Richard I of Capua
Content: Jordan I of Capua ; Jonathan, Count of Carinola ; Bartholomew, Count of Carinola ; an unnamed daughter, married William of Montreuil ; an unnamed daughter, married Lando of Gaeta Richard married Fredescende d'Hauteville, daughter of Tancred of Hauteville and sister of Robert Guiscard Duke of Apulia. Together they had: 
Title: Lando IV of Capua
Content:  Lando IV (Landone) was the Lombard prince of Capua from December 1091 until 19 June 1098, in opposition to Norman prince Richard II. Lando belonged to the family of the counts of Teano. The Catalogus Principum Capuae claims that Richard was "for years expelled by the Lombard counts and was made prince of Aversa [only], and afterwards he again held Capua", without naming any of the Lombard counts. A charter from 27 January 1093 shows that for a time Richard II held Capua, but lost it again and was not finally reinstated until he successfully besieged it in 1098.
Title: Richard III of Gaeta
Content:  Richard was the son of Count Bartholomew of Carinola, as attested by Peter the Deacon, who calls him Bartholomei de Caleno filius in his Chronicon Cassinense. Richard himself refers to his father in the grandiose title he used in charters in November 1123 and November 1127: "Richard, ordained by divine clemency consul and duke of the aforesaid city [of Gaeta], son of Lord Bartholomew of old, descended from the princes of Capua and the counts of Carinola of pious memory." Bartholomew was a brother of Prince Jordan I of Capua and Count Jonathan I of Carinola. Richard was thus a member of the extended Drengot family. Duke Jonathan, who preceded Richard at Gaeta, may have been the son of Count Jonathan. Graham Loud presents an alternate genealogy, making Richard a son of Count Jonathan and Duke Jonathan his nephew, being a son of an unnamed brother of Richard. Richard was married to a woman named Anna. Their son, Jonathan (died 1162×66), inherited the county of Carinola and was compensated for the loss of Gaeta, which passed to the crown after Richard's death, by the grant of the county of Conza.
