After the death of Lothar II, the Treaty of Meerssen (August 870) divided Lotharingian territories between Louis the German and his half-brother Charles the Bald.
The chronicler Flodoard of Reims recorded that, in 921, Ricwin (Ricuni infidelis) opposed Charles the Simple, presumably as part of the Revolt of the Nobles of 920.
Ricwin, weak in bed, was killed in 923 by Boso of Provence, uncle of Rudolf, who was elected king of France that same year.
Ricwin first married a daughter whose name is unknown of Engelram, Chamberlain to Charles the Bald, and his wife Friderada.
No children are recorded, though there is speculation by Evrard that Cunigunda's son Gilbert (Giselbert) was fathered by Ricwin.
