An inquiry into the remarkable instances of history and Parliament records used by the author of The unreasonableness of a new separation on account of the oaths, whether they are faithfully cited and applied.
Brady, Robert, 1627?-1700.

The Author's Words, pag. 32.

A King de facto, according to our Law, (as I said,) is one in quiet possession of the Crown, by Consent of Parliament, with∣out hereditary Right; such as Henry IV. V. VI. VII. were all thought to be by those who made this Distinction. For, as far as I can find, the Distinction of a King de facto, and de jure, was then started, when the House of York so much insisted on their hereditary Right, and so many of our Kings had governed the Kingdom by Consent with∣out it; therefore the Lawyers, to find a sufficient Salvo for the Kings of the House of Lancaster, framed this Distinction of Kings de facto, and de jure.
