The Morrígan is mainly associated with [[war]] and [[fate]], especially with foretelling doom, death, or victory in battle. In this role she often appears as a crow, the ''[[badb]]''. She incites warriors to battle and can help bring about victory over their enemies. The Morrígan encourages warriors to do brave deeds, strikes fear into their enemies, and is portrayed washing the bloodstained clothes of those fated to die. She is most frequently seen as a goddess of battle and war and has also been seen as a manifestation of the [[Sovereignty goddess|earth- and sovereignty-goddess]],{{sfn|Ó hÓgáin|1991|pp=307–309}}<ref name="Koch, John T. 2006">Koch, John T.
