LOUIS "le Jeune" ([825]-near Brescia 12 Aug 875, bur Milan, San Ambrosio). Regino names "Hludowicum, Hlotharium et Carolum" as the three sons of Emperor Lothar & his wife[648]. He was sent to Italy as king in 844, crowned in Rome in 844 as LOUIS King of Italy by Pope Sergius II. After the Arab sack of Rome in 846, he led troops south to arrange better protection for the city. They started by unsuccessfully attempting to recapture Bari, but more importantly Louis was able to achieve a settlement to the civil war between Benevento and Salerno by arranging a division of territories between the two sides under the Radelgisi et Siginulfi Divisio Ducatus Beneventani signed in early 849[649]. He was crowned joint Emperor LOUIS II in Rome in Apr 850 by Pope Leo IV, ruling jointly with his father. He was sole emperor after the death of his father in 855. He claimed part of the territory inherited by his brother Lothaire, a final settlement being achieved between the three brothers at Orbe, Jura in Oct 856. He acquired Geneva, Lausanne and Sitten from his brother Lothaire in 859. After the death of his brother Charles in 863, Louis and his surviving brother Lothaire agreed a division of Charles's territories, Louis taking half of Provence and part of Transjuranian Burgundy. On the death of his brother Lothaire, their uncle Charles II "le Chauve" King of the West Franks appropriated his territories ignoring Emperor Louis's protests[650]. From his base at Benevento King Louis began preparations to recapture Bari from the Arabs in 865. He negotiated Byzantine naval help for the project in 868/69, the agreement being confirmed by his daughter's betrothal. However, the Byzantine fleet which arrived in summer 869 departed abruptly, although the reasons for this are unclear, and the betrothal was terminated. Bari eventually fell in Feb 871 to a combined Frankish/Lombard army[651]. [Betrothed ([842/43], contract broken) to [--- of Byzantium], daughter of Emperor THEOPHILOS & his wife Theodora ---. This betrothal is referred to by Settipani[652]. According to the Continuata Constantinopolitana, the negotiations did not get as far as a formal betrothal[653].] m (betrothed 851 before 5 Oct, [852]) ENGELBERGA, daughter of --- (-[896/901]). "Hludowicus…imperator augustus" names "sponsam nostram Angilbergam" in a charter dated 5 Oct [860] by which he granted Campo Miliacio in the county of Modena to her[654]. Her origins are unknown. According to some secondary sources[655], she was Engelberga, daughter of Adalgis [I] Count of Parma, Duke of Spoleto [Supponidi]. Jean-Noël Mathieu highlghts that this is supported only by Count Suppo [III] being referred to in 870 as consobrinus of the emperor´s wife[656]. The origin of Empress Engelberga is discussed briefly by Odegaard, who dismisses the proposed Supponidi connection but proposes no alternative theory[657]. Some clue is also suggested by Emperor Karl III who confirmed grants to "Angilbergam…Hludouuici…imperatori consobrini nostri coniugem augustam, dilectam sororem nostram" by charter dated 23 Mar 880[658]. In addition, Emperor Karl refers to Engelberga's daughter as "neptam nostram Hermingardam…filioque suo Hludouuico nepoti nostro et sororibus eius"[659]. Jean-Noël Mathieu suggests that these references could mean that Engelberga was the uterine half-sister of the emperor, the daughter of his mother Emma by an otherwise unknown first marriage[660]. However, this assumes that "soror" and "neptis" should be interpreted in these documents in their strictest sense, although a wide variety of meaning is attributed to the terms in contemporary sources. Another possibility is that Engelberta was related to Emperor Karl III through his wife Richardis who was the daughter of Graf Erchanger (see FRANCONIA). The different possibilities are too numerous and uncertain for further speculation about Engelberga´s parentage to be worthwhile. Engelberga´s over-bearing manner 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[661]. "Hludowicus…imperator augustus" granted the abbey of San Salvatore to "nostra coniux…Angilberga ante filiam…nostrum Hermengardem" by charter dated at Venosa 28 Apr 868[662]. Suspected of supporting the usurpation of her son-in-law King Boso, she was imprisoned in a convent in Alemannia by Charles III "le Gros" King of the East Franks, but returned to Italy with his permission in Oct 882[663]. Abbess of San Sisto at Piacenza in 896. Emperor Louis II & his wife had two children
