Iljko

An unnamed son of Domagoj, according to older historiography named Iljko which is probably an erroneous translation of, was a duke in Croatia from 876 until 878.
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. 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. Recently were attempts identifying him with the duke Višeslav of Croatia.
