To deprive royalty of these mysterious attributes, and to establish the principle that Kings reigned by a right in no respect differing from the right by which freeholders chose knights of the shire, or from the right by which judges granted writs of Habeas Corpus, was absolutely necessary to the security of our liberties.
Thus the Convention had two great duties to perform.

The first was to clear the fundamental laws of the realm from ambiguity.

The second was to eradicate from the minds, both of the governors and of the governed, the false and pernicious notion that the royal prerogative was something more sublime and holy than those fundamental laws.

The former object was attained by the solemn recital and claim with which the Declaration of Right commences; the latter by the resolution which pronounced the throne vacant, and invited William and Mary to fill it.
The change seems small.

Not a single flower of the crown was touched.
Not a single new right was given to the people.
