Who did Henry VIII want to betroth Mary Queen of Scots to?
Henry wanted Mary betrothed to his son Edward so that Scotland
and England would ruled by one monarch. He didn't get his way then
and attacked Scotland in the "Rough Wooing". It back fired on Henry
when Mary's mother sent her to France to be married to the
Dauphin.
It was Mary's son, James, who eventually fulfilled Henry's
dream, when he became king of both Scotland and England at
Elizabeth I's death.
