Where can I find more on the history of popes? I remember one called Princes of the Church.
The title, Princes of the Church is unfamiliar to me. There are, however, at least two books that should still be in print which will give short biographies and accounts of the papal reigns of all the popes from Peter to John Paul II. One is The Pope Encyclopedia, by Matthew Bunson (Crown Trade Paperbacks, New York). It was published in 1995. The second book is The Oxford Dictionary of Popes, by J.N.D. Kelly (Oxford University Press).
