In 400AD the kingdom of Dál Riata emerged in the western Highlands and began to aggressively expand, conquering land in Ulster and more pertinently Scotland where it spread the Goidelic language. Dál Riatan expansion was checked at around 600AD, but 200 years later Gaelic kings took control of Pictish kingdoms through marriage and merged the new acquisitions with Dál Riata to form ''Rìoghachd na h-Alba'' - the kingdom of Scotland. This kingdom was the platform by which Gàidhlig came to dominate Scottish language north of the river forth and also in the Southern Uplands. | In 400AD the kingdom of Dál Riata emerged in the western Highlands and began to aggressively expand, conquering land in Ulster and more pertinently Scotland where it spread the Goidelic language.
