The Hebrides (/ˈhɛbrɨdiːz/; Scottish Gaelic: Innse Gall; Old Norse: Suðreyjar) comprise a widespread and diverse archipelago off the west coast of mainland Scotland. There are two main groups: the Inner and Outer Hebrides. These islands have a long history of occupation dating back to the Mesolithic, and the culture of the residents has been affected by the successive influences of Celtic, Norse, and English-speaking peoples.
