One man's struggle Pius IX and the change in papal authority in the nineteenth century /

ONE MAN’S STRUGGLE: PIUS IX AND THE CHANGE IN PAPAL AUTHORITY IN THE NINETEENTH CENTURY Andrew Paul Dinovo This thesis examines papal authority in the nineteenth century in three sections. The first examines papal issues within the world at large, specifically those that focus on the role of the Church within the political state. The second section concentrates on the authority of Pius IX on the Italian peninsula in the mid-nineteenth century. The third and final section of the thesis focuses on the inevitable loss of the Papal States within the context of the Vatican Council of 1869-1870. Select papal encyclicals from 1859 to 1871 and the official documents of the Vatican Council of 1869-1870 are examined in light of their relevance to the change in the nature of papal authority. Supplementing these changes is a variety of seminal secondary sources from noted papal scholars. Ultimately, this thesis reveals that this change in papal authority became a point of contention within the Church in the twentieth century.
