Scots-language literature is literature, including poetry, prose and drama, written in the Scots language in its many forms and derivatives. Middle Scots became the dominant language of Scotland in the late Middle Ages. The first surviving major text in Scots literature is John Barbour's Brus (1375). Some ballads may date back to the thirteenth century, but were not recorded until the eighteenth century. In the early fifteenth century Scots historical works included Andrew of Wyntoun's verse Orygynale Cronykil of Scotland and Blind Harry's The Wallace. Much Middle Scots literature was produced by makars, poets with links to the royal court, which included James I, who wrote the extended poem The Kingis Quair. Writers such as William Dunbar, Robert Henryson, Walter Kennedy and Gavin Douglas
