The Two Princes Edward and Richard in the Tower (1878.) by Sir John Everett Millais
The Princes in the Tower, Edward V of England (November 4, 1470 – 1483) and his brother, Richard of Shrewsbury, 1st Duke of York (17 August 1473 – 1483?), were two sons of Edward IV of England and Elizabeth Woodville.
Young Princes Murdered in the Tower (1786) by James Northcote
Both princes were declared illegitimate by an Act of Parliament of 1483 known as Titulus Regius. Their uncle, Richard III of England, placed them both in the Tower of London (then a royal residence as well as a prison) in 1483. There are reports of their early presence in the courtyards etc., but there are no records of them having been seen after the summer of 1483. Their fate remains unknown, and it is presumed that they either died or were killed there. There is no record of a funeral.
Burial of the Princes in the Tower (1786) by James Northcote
In 1674, the skeletons of two children were discovered under the staircase leading to the chapel, during the course of renovations to the White Tower. At that time, these were believed to have been the remains of the two princes. On the orders of Charles II the remains were reburied in Westminster Abbey. In 1933, the grave was exhumed and found to contain both human and animal bones; however precise identification of the age and sex was not then possible (Source)
