The purpose of this thesis is to present a thorough discussion of the origins of St. John's College, and a narrative of its subsequent one hundred years of development, dating from its establishment by Bishop Robert Machray in 1866. The approach is generally chronological. Following a discussion of the College's origins as the outgrowth of mission schools, the Red River Academy, and Bishop Anderson's St, John's College, the emphasis of the narrative gradually shifts towards the relationship between the College and the University of Manitoba. Financial difficulties experienced over the years are pointed out and an attempt is made throughout to trace the changes in the teaching staff and in the scope of the curriculum.
