Based on a wealth of documents long buried in the Vatican archives, Prisoner of the Vatican tells the story of the Church's secret attempt to block the unification of Italy and seize control - not in ancient times, but in the late nineteenth century. For more than fifty years, the pope was a self-imposed prisoner within the Vatican walls, planning to flee Italy, to return only as the restored ruler of Rome and the Papal States. The scheme to dismantle the newborn Italian nation involved not only the cardinals and the Curia but also attempts to exploit the rivalries among France, Germany, Austria, Spain, and England.
