on Carlos (1545-68), the son of Philip II
of Spain, was of vicious character and feeble intellect, and was
deprived by his father of the right of succession in favor of the
Archduke Rudolf. In 1567 he was accused, on a statement made
under confession, of plotting his fathers murder, though it
is more probable that the intended victim, who had not been named,
was the Duke of Alva. The death of Don Carlos in the following
year was attributed by William of Orange to his fathers
orders. [World Wide Illustrated Encyclopedia, 1935]
