Robert I (11 July 1274 – 7 June 1329), popularly known as Robert the Bruce (Scottish Gaelic: Raibeart an Bruis), was King of Scots from 1306 to his death in 1329. One of the most renowned warriors of his generation, Robert 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 kingdom and is now revered in Scotland as a national hero. Robert was a fourth great-grandson of King David I, and his grandfather, Robert de Brus, 5th Lord of Annandale, was one of the claimants to the Scottish throne during the "Great Cause". As Earl of Carrick, Robert the Bruce supported his family's claim to the Scottish throne and took part in William Wallace's revolt against Edward I of England. Appointed in 1298 as a Guardian of Scotland alongside his chief rival for the throne, John Comyn of Badenoch, and William Lamberton, Bishop of St Andrews, Robert resigned in 1300 because of his quarrels with Comyn and the apparently imminent restoration of John Balliol to the Scottish throne. After submitting to Edward I in 1302 and returning to "the king's peace", Robert inherited his family's claim to the Scottish throne upon his father's death. Bruce's involvement in John Comyn's murder in February 1306 led to his excommunication by Pope Clement V (although he received absolution from Robert Wishart, Bishop of Glasgow). Bruce moved quickly to seize the throne, and was crowned king of Scots on 25 March 1306. Edward I's forces defeated Robert in the Battle of Methven, forcing him to flee into hiding, before re-emerging in 1307 to defeat an English army at Loudoun Hill and wage a highly successful guerrilla war against the English. Robert I defeated his other opponents, destroying their strongholds and devastating their lands, and in 1309 held his first parliament. A series of military victories between 1310 and 1314 won him control of much of Scotland, and at the Battle of Bannockburn in 1314, Robert defeated a much larger English army under Edward II of England, confirming the re-establishment of an independent Scottish kingdom. The battle marked a significant turning point, with Robert's armies now free to launch devastating raids throughout northern England, while he also expanded the war against England by sending armies to invade Ireland, and appealed to the Irish to rise against Edward II's rule.
