Episcopal election in Western Christianity evolved considerably over the course of the fifth to the twelfth centuries. In the early part of this period, an open electorate consisting of the clergy and the people (clerus et populus), as well as the diocesan clergy and the metropolitan archbishop, all took part in the election and consecration of a new bishop. Over the course of several centuries, the local prince came increasingly to dominate the process due both to Germanic and Roman traditions of the role of the prince and to the growth in power of the local rulers over the course of the Middle Ages. Efforts to harmonize the discordant views of a “democratic” versus an elite (either princely or clerical) electorate with the ideals of canon law, which forbade lay participation in episcopal election, led to assertions that the clergy were to elect the bishop with the people and the prince giving their assent to the bishop-elect. However, with the Gregorian reforms of the twelfth century, the right of the clergy in episcopal elections became preeminent as the reformers sought to enforce the canon laws and exclude the laity from episcopal election, especially in light of past princely abuse. Despite the apparent victory of the reformers in the Investiture Controversy, the local ruler continued to play a preeminent role in episcopal appointments (or elections) into modern times, though the principle of election “by the clergy and the people” fell into disuse.
