Henry and the Tower

H henry could not marry elizabeth if she was considered illegitimate. So he had to get parliament to repeal the titulus regius. And after they did, henry also ordered all previous copies of it to be destroyed. For a time, the text of that document was lost, until it was rediscovered in the crowland chronicle. It does not appear that henry launched any kind of investigation into what had happened to the princes in the tower or into richard's actions in 14 83. Such an investigation would have unearthed information that would have undermined his own claim to the throne.
