Karl Hefele's 'Conciliengeschichte' was one of the most significant works of Catholic historical scholarship in the nineteenth century. William Clark's translation presents the first two and a half volumes of Hefele's study, up to the Second Council of Nicaea (the German original is nine volumes, through the year 1536). This study marked a new stage in the study of conciliar action.
