The Declaration of Arbroath is a declaration of Scottish independence, made in 1320. It is in the form of a letter submitted to Pope John XXII, dated 6 April 1320, intended to confirm Scotland's status as an independent, sovereign state and defending Scotland's right to use military action when unjustly attacked. Generally believed to have been written in the Arbroath Abbey by Bernard of Kilwinning, then Chancellor of Scotland and Abbot of Arbroath, and sealed by fifty-one magnates and nobles, the letter is the sole survivor of three created at the time. The others were a letter from the King of Scots, Robert I, and a letter from four Scottish bishops which all presumably made similar points.
The Declaration was part of a broader diplomatic campaign which sought to assert Scotland's position as a kingdom, rather than being a feudal land controlled by England's Norman kings, as well as lift the excommunication of Robert the Bruce. The Pope had recognised Edward I of England's claim to overlordship of Scotland in 1305 and Bruce was excommunicated by the Pope for murdering John Comyn before the altar in Greyfriars Church in Dumfries in 1306. The Declaration made a number of much-debated rhetorical points: that Scotland had always been independent, indeed for longer than England; that Edward I of England had unjustly attacked Scotland and perpetrated atrocities; that Robert the Bruce had delivered the Scottish nation from this peril; and, most controversially, that the independence of Scotland was the prerogative of the Scottish people, rather than the King of Scots.
