Britain's only ever "joint monarchs"
William III (1689-1702) & Mary II (1689-94) changed the course of the
entire country's history, coming to power through a coup (which involved
Mary betraying her own father), reestablishing parliament on a new
footing, and, through commiting Britain to fighting France, initiating
an immensely long period of warfare and colonial expansion. Jonathan
Keates' wonderful book makes both monarchs vivid, the cold, shrewd
"Dutch" William and the shortlived Mary, whose life and death inspired
Purcell to write some of his greatest music.
