The Hebrides ( /ˈhɛbrɨdiːz/; Scottish Gaelic: Innse Gall) comprise a widespread and diverse archipelago off the west coast of 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. This diversity is reflected in the names given to the islands, which are derived from the languages that have been spoken there in historic and perhaps prehistoric times.
