An unnamed son of Domagoj, according to older historiography named Iljko which is probably an erroneous translation of Latin : Yllicus, was a duke ( Croatian : knez ) in Croatia from 876 until 878. [1]
The name Iljko has later generally been accepted that it was a consequence of a wrong translation of the Chronicle of Dandolo, a Latin text written by Andrea Dandolo in the 14th century. [2] The name of the unknown duke was probably the result of Dandolo's fantasy. During the specified timespan a son of Domagoj ruled Croatia, but his name was not preserved (as mentioned by John the Deacon). Recently were attempts identifying him with the duke Višeslav of Croatia. [3] [4]
