They are one of the oldest clans in the Highlands and owned large tracts of land in Argyll as well as the Inner Hebrides. Many early MacLeans became famous for their honour, strength and courage in battle. They were involved in many clan skirmishes with the MacKinnons, Camerons, MacDonalds and Campbells. They were fierce Jacobites fighting in all of the Jacobite risings.
