Henry VII denounces Perkin Warbeck to Margaret, Duchess of
Burgundy. Although most probably Flemish in origin, Warbeck claimed
to be Richard of Shrewsbury, 1st Duke of York, the younger son of
Edward IV, who was imprisoned in the Tower along with his brother
Edward V under the kingship of Richard III. Edward IV's sister
Margaret of Burgundy, however, refused to heed this denunciation,
officially recognising Warbeck as her nephew.
