What happened to the other Dukes of York?
From our UK edition
Old Dukes of York Prince Andrew is the 14th royal to have held the title Duke of York (three were styled the Duke of York and Albany). What happened to the other Dukes of York? — Two were killed in battle: Edward of Norwich at Agincourt in 1415 and Richard of York at the Battle of Wakefield in 1460. One, Richard of Shrewsbury, was murdered; he was one of the ‘princes in the tower’ who disappeared in 1483. — Barring unexpected events, Andrew will be the first Duke of York since Prince Frederick in the early 19th century not to progress onto the throne. Unlike Andrew, Prince Frederick moved closer to the throne throughout his life and was heir presumptive when he died in 1827 of overindulgence. He left vast debts incurred through gambling.
