THIS single postulatum, the vacancy of the throne, being once established, the rest that was then done followed almost of course. For, if the throne be at any time vacant (which may happen by other means besides that of abdication; as if all the bloodroyal should fail, without any successor appointed by parliament;) if, I say, a vacancy by any means whatsoever should happen, the right of disposing of this vacancy seems naturally to result to the lords and commons, the trustees and representatives of the nation. For there are no other hands in which it can so properly be intrusted; and there is a necessity of it's being intrusted somewhere, else the whole frame of government must be dissolved and perish. The lords and commons having therefore determined this main fundamental article, that there was a vacancy of the throne, they proceeded to fill up that vacancy in such manner as they judged the most proper. And this was done by their declaration of 12 February 1688[b], in the following manner: "that William and Mary, prince and princess of Orange, be, and be declared king and queen, to hold the crown and royal dignity during their lives, and the life of the survivor of them; and that the sole and full exercise of the regal power be only in, and executed by, the said prince of Orange, in the names of the said prince and princess, during their joint lives; and after their deceases the said crown and royal dignity to be to the heirs of the body of the said princess; and for default of such issue to the princess Anne of Denmark and the heirs of her body; and for default of such issue to the heirs of the body of the said prince of Orange." [Footnote b: Com. Journ. 12 Feb. 1688.] PERHAPS, upon the principles before established, the convention might (if they pleased) have vested the regal dignity in a family intirely new, and strangers to the royal blood: but they were too well acquainted with the benefits of hereditary succession, and the influence which it has by custom over the minds of the people, to depart any farther from the antient line than temporary necessity and self-preservation required. They therefore settled the crown, first on king William and queen Mary, king James's eldest daughter, for their _joint_ lives; then on the survivor of them; and then on the issue of queen Mary: upon failure of such issue, it was limited to the princess Anne, king James's second daughter, and her issue; and lastly, on failure of that, to the issue of king William, who was the grandson of Charles the first, and nephew as well as son in law of king James the second, being the son of Mary his only sister. This settlement included all the protestant posterity of king Charles I, except such other issue as king James might at any time have, which was totally omitted through fear of a popish succession. And this order of succession took effect accordingly.
