Properly de-accessioned. Boards. Later edition printed in the year of the author's death. The first dialogue appears to have been printed under this title as early as 1691. The Dialogues have to do with the legitimacy of the claim for the divine right of Kings and the nature of English Constitutional government. Tyrrell also explores the question of under what circumstances, if any, a monarch may forfeit his title to the crown. The reigns considered include those of King William, the Norman, King James II, King William and Queen Mary, King Charles I, and others.

Tyrrell (1643-1718) was a Whig historian and a friend of John Locke.
