Plenimir (
Bulgarian: Пленимир) was a Bulgarian prince (
knyaz), the son of emperor (tsar)
Peter I (r. 927–969). He was one of three sons of Peter I, all born between 931 and 944.[1] Historiography is well-informed on his two brothers, Boris II and Roman, while scarce information exist on Plenimir.[1] His brothers reigned as Bulgarian tsars
Boris II (r. 969–971[citation needed]) and
Roman (r. 977–991[citation needed]).
