Robert II of Scotland Send to Google Classroom: Robert II of Scotland ruled as king from 1371 to 1390 CE. Born Robert Stewart, he succeeded the heirless David II of Scotland (r. 1329-1371 CE) and so founded the royal house of Stewart. Dividing Scottish estates between his many offspring, Robert redrew the political map of his kingdom and effectively replaced half of the nobility with his family and allies, a process often called the 'Stewartisation' of Scotland. Although a more capable leader in his youth than medieval historians liked to portray him, Robert's reign did witness a decline in the wealth of the Crown and the creation of bitter rivalries amongst the great baronial families which would cause no end of problems for his successor, his son Robert III of Scotland (r. 1390-1406 CE).
