That being said, it seems clear that Gaelic had ceased to be the language of Scotland by 1400 at the latest. It disappeared from the central lowlands by c1350 and from the eastern coastal lowlands north of the Mounth not long afterwards. By the mid-1300s English in its Scottish form - what eventually came to be called Scots -- emerged as the official language of government and law. Scotland's emergent nationalism in the era following the conclusion of the Wars of Scottish Independence was organized around and through Scots as well. For example, the nation's great patriotic literature including John Barbour's The Brus (1375) and Blind Harry's The Wallace (bef. 1488) was written in Scots, not Gaelic. It was around this time that the very name of Gaelic began to change. Down through the 14th century, Gaelic was referred to in English as Scottis, i.e. the language of the Scots. By the end of the 15th century, however, the Scottish dialect of Northern English had absorbed that designation. English/Scots speakers referred to Gaelic instead as Yrisch or Erse, i.e. Irish. King James IV (d. 1513) thought Gaelic important enough to learn and speak. However, he was the last Scottish monarch to do so.
