Iain Borb MacLeod (1392–1442) is considered to be the 6th Chief of Clan MacLeod. He is the first MacLeod chief to which heraldry can be assigned. Clan tradition states that he was a minor at the time of his father's death and for six years an incompetent guardian led the clan to its lowest point in clan history. After reaching the age of maturity, Iain Borb managed to acquire some of the clan's lost lands and led his clan and his kinsmen in the Battle of Harlaw, in 1411. Iain Borb was wounded in the head during the conflict; the wound never completely healed and confined him to his home on Pabbay for much of his life. Tradition states that he died when this wound re-opened during a fencing/wrestling match. There is some disagreement as to which of his sons was the eldest; however, his son William Dubh was the one who finally succeeded to the chiefship, following his death in 1442.
