Alba

Caledonia is the Roman name for Scotland. Alba is the Scottish Gaelic name for Scotland. 

            The first Gaels, the Scots, arrived in Scotland from Ireland around 450 AD and settled in Argyll, which they called Dal Riata. They were fiercely resisted by the established Pictish people and it was not until 843 that the Gaelic leader, Kenneth MacAlpin united the Picts and the Gaels and became the first ruler of Alba which comprised most of Scotland north of rivers Forth and Clyde. “Alba” has since remained the Gaelic name for Scotland.
