Which Pope refused Henry VIII a divorce? Who was the Pope who tried to bring about world peace on the eve of World War I? And can you name the only English pontiff? Whether you are Catholic or not, there's no question that the papacy represents a major thread of world history. In this guide, they are listed aphetically according to the Papal names (Pius, John Paul, Alexander) but indexes also list the Popes by their family names (Borgia, Woytilja, Ratzinger). There is also a two-thousand-year chronology, and Michael Walsh contributes an introduction in which he describes the role of the Papacy throughout history.
