Robert Burns (also known as Robin) was a Scottish poet and a lyricist. He is widely regarded as the national poet of Scotland, and is celebrated worldwide. He is the best known of the poets who have written in the Scots language. He also wrote in English and a "light" Scots, accessible to an audience beyond Scotland. He is regarded as a pioneer of the Romantic movement and after his death became a great source of inspiration to the founders of both liberalism and socialism. A cultural icon in Scotland and among the Scottish Diaspora around the world, celebration of his life and work became almost a national charismatic cult during the 19th and 20th centuries, and his influence has long been strong on Scottish literature.
