Execution in Pontefract Castle

On 25 June 1483, Gloucester had Elizabeth Woodville's son Richard Grey and brother Anthony, Earl Rivers, executed in Pontefract Castle, Yorkshire. By an act of Parliament, the Titulus Regius (1 Ric. III), it was declared that Edward IV's children with Elizabeth were illegitimate on the grounds that Edward IV had a precontract with the widow Lady Eleanor Butler, which was considered a legally binding contract that rendered any other marriage contract invalid. One source, the Burgundian chronicler Philippe de Commines, says that Robert Stillington, Bishop of Bath and Wells, carried out an engagement ceremony between Edward IV and Lady Eleanor.
