IAGO ab IDWAL ap MEURIG (d. 1039), king of Gwynedd;
a great grandson of Idwal Foel (q.v.). After successive usurpations of legitimate authority in Gwynedd between 986 and 1033 (see Maredudd ap Owain, Llywelyn ap Seisyll, Rhydderch ap Iestyn) the old line was restored in the person of Iago. A brief rule of six years ended in his murder and replacement by Gruffudd ap Llywelyn ap Seisyll. His son, Cynan, was the father of Gruffudd ap Cynan (q.v.) who finally re-established the house of Rhodri the Great as the senior dynasty in North Wales.
