peasants died of cold and hunger. Orderic Vitalis estimated that "more than 100,000" people from the North died from hunger. In the centuries following, many abbeys and priories were built in Yorkshire. Norman landowners increased their revenues and established new towns such as Barnsley, Doncaster, Hull, Leeds, Scarborough and Sheffield, among others. Of towns founded before the conquest, only Bridlington, Pocklington, and York continued at a prominent level. In the early 12th century, people of Yorkshire had to contend with the Battle of the Standard at Northallerton with the Scots. Representing the Kingdom of England led by Archbishop Thurstan of York, soldiers from Yorkshire defeated the more numerous Scots. 1300s: Scottish War of Independence and Mass Deaths The population of Yorkshire boomed until it was hit by the Great Famine of 1315. It did not help that after the English defeat in the Battle of Bannockburn in 1314, the Scottish army rampaged throughout northern England, and Yorkshire was no exception. During The Great Raid of 1322, they raided and pillaged from the suburbs of York, even as far as East Riding and the Humber. Some like Richmond had to bribe the Scots to spare the town. The Black Death then reached Yorkshire by 1349, killing around a third of the population. 1400s–1600s: Royal revolts 1400s: Wars of the Roses When King Richard II was overthrown in 1399, antagonism between the House of York and the House of Lancaster, both branches of the royal House of Plantagenet, began to emerge. Eventually the two houses fought for the throne of England in a series of civil wars, commonly known as the Wars of the Roses. Some of the battles took place in Yorkshire, such as those at Wakefield and Towton, the latter of which is known as the bloodiest battle ever fought on English soil.
