Einion ap Cunedda (c.
420-500; reigned from
the 470s) ( ), also known as Einion Yrth
('the Impetuous') was a king of Gwynedd
.
One of the
sons of Cunedda, it is
believed he traveled with his father to North Wales
in the early
450s to expel Irish
raiders from
the region. After his father's death, Einion inherited
control over the newly founded kingdom of Gwynedd.
Aided by his brother
Ceredig, ruler of Ceredigion, and his nephew Meirion, ruler of Meirionnydd
, Einion built upon his father's successes and
further established his family's rule in the region. He was
succeeded by two sons;
Cadwallon
Lawhir and
Owain
Ddantgwyn.
