Who and what is the story of the princes in the Tower of London?

Edward V son of Edward IV was taken to the tower along with his younger brother. Edward V was to be the King after Edward IVs death, but was declared illegitimate, therefore he could not be king. He and his brother were taken to the tower in fear of their safety after this news. They were under the care of their Uncle Richard Duke of Gloucester later Richard III. The princes were taken to the tower and never heard from again. The rumor is that either Richard III hired someone to smother them or Henry VII had them killed. It has never been proven who actually did it, both had reason to though. Later there were skeletons found in the tower believed to be those of the two princes.
