Well, Richard Duke of York had been a popular Governor in Ireland, mainly because he left the Irish to themselves. He appears to have been more popular in Ireland than the Butler Earls of Ormond and Wiltshire were at a similar time. His son, when Edward IV, inherited a lot of goodwill, and tended to run Ireland in a somewhat hands-off manner, which the Irish certainly appreciated. The few times he tried to impose rule on Ireland, it was less successful.Though with the Lancaster faction sitting on England's throne, how will this affect their relationship with Ireland?
That the Yorkists were popular can be demonstrated by Irish support for both Lambert Simnel and Perkin Warbeck.
