In the 13th century, despite Edgar's quitclaim, Scottish forces attempted to conquer parts of Suðreyjar, culminating in the indecisive Battle of Largs. In 1266, the matter was settled by the Treaty of Perth, which transferred the whole of Suðreyjar to Scotland, in exchange for a very large sum of money. The Treaty expressly preserved the status of the rulers of Suðreyjar; the Clann Ruaidhri lands, excepting Bute, Arran, and Jura, became the "Lordship of Garmoran", a quasi-independent crown dependency, rather than an intrinsic part of Scotland.
