The Princes in the Tower

In the summer of 1483, the two young sons of King Edward IV of England — Edward, aged 12, and Richard, aged 9 — disappeared after being confined to the Tower of London. Their uncle, Richard III, had declared them illegitimate and taken the throne. The princes were never seen in public again. Whether Richard III ordered their deaths, or they were killed by another faction, remains one of history's greatest unsolved mysteries.
