After marrying Elizabeth Woodville in 1464, Edward increasingly relied on her family, who competed with the Nevilles for lands and positions.
He also blocked a proposal that his younger brother and heir, George, Duke of Clarence, should marry Warwick's eldest daughter Isabel Neville.
This was followed in May by a second rebellion, under a figure known as Robin of Holderness, demanding the restoration of Henry Percy, traditional Earl of Northumberland.
This was quickly suppressed by John Neville, the current Earl of Montagu, who killed its leader but Robin of Redesdale escaped him.
His mantle was temporarily assumed by someone else, apparently Sir John Conyers, when Warwick raised a further rebellion early in 1470.
