Lothar II (c. 835; † August 8th 869 at Piacenza ) of the family of the Carolingians was 855-869 Frankish King.
Lothar was the second son of Emperor Lothair I and his wife Ermengarde of Tours. After the death of Lothar I († 855) was the Empire - the Lotharii Regnum or middle kingdom - between his three sons divided ( Reich division of Prüm ): The eldest son Ludwig received Italy and the title of Emperor, Lothair II got Lotharingia ( from which the later Lorraine was born), including the residence of Aachen and the youngest son of Charles of Provence and Burgundy was awarded.

The Pope revoked the decision and excommunicated the archbishops of Cologne and Gunthar Theutgaud von Trier, who had been at the Synod of Metz the driving force. Pope Hadrian II finally allowed Lothar, personally present his case in Rome. On the way back this trip but died Lothar, so that a final decision was unnecessary.
