Kingdom of Alba

The Kingdom of Alba (Latin: Scotia; Scottish Gaelic: Alba) was the Kingdom of Scotland between the deaths of Donald II in 900 and of Alexander III in 1286. The latter's death led indirectly to an invasion of Scotland by Edward I of England in 1296 and the First War of Scottish Independence.

Alba included Dalriada, but initially excluded large parts of the present-day Scottish Lowlands, which were then divided between Strathclyde and Northumbria as far north as the Firth of Forth. Fortriu, a Pictish kingdom in the north, was added to Alba in the tenth century.

Until the early 13th century, Moray was not considered part of Alba, which was seen as extending only between the Firth of Forth and the River Spey.
