Plantagenet Alliance was founded by Stephen Nicolay according to Joshua Rozenberg, a British solicitor, legal commentator, and journalist, but Vanessa Roe contested that Plantagenet Alliance came about as a result of her contacting York City Council.
According to a BBC report and The Guardian journalist Joshua Rozenberg, Stephen Nicolay, a descendant of Richard III's sister, founded the Plantagenet Alliance shortly after confirmation, in February 2013, that it had been Richard's remains that had been discovered the previous year. Joshua Rufus Rozenberg QC (hon) (born 30 May 1950) is a British solicitor, legal commentator, and journalist. 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.
