Andrew Harclay, 1st Earl of Carlisle, English military leader
Andrew Harclay, 1st Earl of Carlisle (ca. 1270 – 3 March 1323), alternatively Andreas de Harcla, was an important English military leader in the borderlands with Scotland during the reign of Edward II. Coming from a knightly family in Westmorland, he was appointed sheriff of Cumberland in 1311. He distinguished himself in the Scottish Wars, and in 1315 repulsed a siege on Carlisle Castle by Robert the Bruce. Shortly after this, he was taken captive by the Scots, and only released after a substantial ransom had been paid. His greatest achievement came in 1322, when he defeated the rebellious baron Thomas of Lancaster at the Battle of Boroughbridge on 16–17 March. For this he was created Earl of Carlisle.

As one of the main military leaders on the border to Scotland, Harclay became frustrated with Edward II's inactivity, particularly the humiliating English defeat at the Battle of Old Byland on 14 October 1322, which made it clear that the war could not be won. Harclay initiated negotiations with the Scots on his own accord, and on 3 January 1323, he signed a peace treaty with Robert the Bruce. The act was without royal sanction, and amounted to treason. The king issued an arrest order for the earl, and on 25 February Harclay was taken into the king's custody. He was arraigned before royal justices on 3 March, denied a hearing, and executed the same day. He was hanged, drawn and quartered, and the various parts of his body displayed in different parts of the country. His alleged treason, capture and execution is described in the Lanercost Chronicle. Only after five years was he allowed a proper burial, but the conviction for treason was never annulled.
