Robert I (11 July 1274 – 7 June 1329), popularly known as Robert the Bruce, was King of Scots from 1306 until his death in 1329. Robert was one of the most famous warriors of his generation, and eventually led Scotland during the First War of Scottish Independence against England. He fought successfully during his reign to regain Scotland's place as an independent country and is today revered in Scotland as a national hero.

Robert I had been suffering from a serious illness from at least 1327. The Lanercost Chronicle and Scalacronica state that the king was said to have contracted and died of leprosy. Jean Le Bel also stated that in 1327 the king was a victim of 'la grosse maladie', which is usually taken to mean leprosy. However, the ignorant use of the term 'leprosy' by fourteenth-century writers meant that almost any major skin disease might be called leprosy.

The earliest mention of this illness is to be found in an original letter written by an eye-witness in Ulster at the time the king made a truce with Sir Henry Mandeville on 12 July 1327. The writer of this letter reported that Robert I was so feeble and struck down by illness that he would not live, 'for he can scarcely move anything but his tongue'. Barbour writes of the king's illness that 'it began through a benumbing brought on by his cold lying', during the months of wandering from 1306 to 1309
