In the Catholic countries of seventeenth- and early eighteenth-century Europe, communities of monks and nuns were growing in number and wealth. They constructed vast buildings, dominated education, and played a large part in the practice and patronage of learning, music, and the arts. This lavishly-illustrated book offers a unique, comparative description of these communities—their wealth, growth, life, and importance—and then explains their catastrophic decline and fall between 1650 and 1815 by reforming rulers, the 'Enlightenment', and the French Revolution. Derek Beales, Professor Emeritus of Modern History, Cambridge, is a Fellow of both the Royal Historical Society and the British Academy.
