Tancred, king of Sicily
(Tancred of Lecce) (tng´krd;, l´ch) (KEY) , b. 1130 or 1134, d. 1194, king of Sicily (119094), illegitimate son of Roger of Apulia and grandson of Roger II of Sicily. On the death of his cousin, William II of Sicily, Tancred was crowned (1190) king. The Sicilian crown was, however, claimed by Constance, who was Williams aunt. Her husband, Holy Roman Emperor Henry VI, made an unsuccessful expedition against Tancred in 1191 and, soon after Tancreds death, deposed (1194) Tancreds infant son, William III.
