ADELCHIS, son of RADELCHIS I Prince of Benevento & his wife Caretruda --- (-murdered 878). The treaty of division between Radelchis Prince of Benevento and Siconulf, dated 849, names "Petrum filium Landonis et Paldefrit filium Paldulfi" and "Adelgisum et Ladelgisum filios meos et Potonem nepotem meum" as sureties/hostages for performance of the agreement[213]. The Annales Beneventani record that "Adelgis germanus frater Radelgarii" succeeded his brother in 854 as ADELCHIS Prince of Benevento[214]. Emperor Louis II occupied Benevento in 866, using it as his southern base particularly to plan the recapture of Bari from the Arabs. During this time, the emperor minted coins in association with Prince Adelchis[215]. The over-bearing manner of Empress Engelberga triggered her arrest, and that of her husband, at Benevento in Aug 871, although their release was negotiated within a month by the bishop of Benevento[216]. Regino records that "Adalgisus dux Beneventanus" rebelled against Emperor Louis in 871, having been corrupted by the Greeks[217]. The Chronicon Vulturnense records that "Adelchis…Langobardorum gentis Princeps" confirmed the privileges of the abbot of Volturno, at the request of "Audoaldi comitis cognati nostri", by charter dated Feb [878][218]. The Chonicon Monasterii Beneventani records that "Adelchis Princeps" was killed in 878[219]. A charter of his son "Aio…Langobardorum gentis princeps", dated May [885], records that "dom Adelchis princip…genitori nostro" was killed by "Potoni fi[lii] Potitionis"[220].

m ADELTRUDA, daughter of ---. "Adelchis…Langobardorum gentis princeps" donated property, at the request of "Adeltrudæ…conjugis nostræ", by charter dated Feb 876[221]. She may have been the sister of Count Audoald, as suggested by the Chronicon Vulturnense which records that "Adelchis…Langobardorum gentis Princeps" confirmed the privileges of the abbot of Volturno, at the request of "Audoaldi comitis cognati nostri", by charter dated Feb [878][222].

 Prince Adelchis & his wife had [ten] children:
