Robert was a grandson of Robert Bruce, and the first in the House of Stewart dynasty. The name came from his ancestor Walter Stewart who was appointed High Steward of Scotland by David I. He had escaped following the defeat of David II at Halidon Hill in 1333 and took over as Guardian of Scotland while David was in exile in France.
He was a mature man of 54 when he succeeded to the throne on the death of David, but he was weak king and did not rule well over the nobles who were critical of him leading to a loss of prestige of the crown. His heir John took over the rule to attempt to restore law and order.
A truce with England in 1384 was short lived, and the border wars continued. In 1388 the Scots under James Douglas won a victory at Otterburn near Newcastle over Henry Percy ‘Hotspur’ of Northumberland.
Robert had 14 legitimate children and at least 7 illegitimate. He was succeeded by his son John who took the name Robert III.
