Plantagenet Alliance was founded by Stephen Nicolay according to Joshua Rozenberg but Vanessa Roe contested that Plantagenet Alliance came about as a result of her refusal to contact York City Council.
However, Vanessa Roe, another member of the group, told Prospect Magazine, in an interview, that the Plantagenet Alliance came about as a result of her contacting York City Council after she had seen a Channel 4 documentary about the exhumation and identification of Richard III's remains.
