Scotland
In Pictland, the Picts started the Kingdom of Alba in the 9th-century. The kingdom began in the land between the River Spey and the River Forth. The Pictish language went extinct, and people in the 10th-century kingdom of Alba spoke the Goidelic language, Scots Gaelic. In time, the kingdom grew. The lands of Moray and Angus became part of the kingdom. The northern parts of Northumbria, south of the River Forth, became part of the kingdom.
