During the 20th century, Catholics accounted for approximately one third of the province's population, and their influence has extended into the political realm. This resource is meant to be an objective collection of brief biographical entries featuring Catholic politicians in Alberta, both on provincial and federal elections. The author, Dr. Austin Mardon, has published other references of Alberta politicians including those featuring Mormons and Anglicans. He is involved in an ongoing project to chronicle all of Alberta's politicians, past and present.
