In 1951, Jim Brazier was consecrated a bishop, to serve as an assistant bishop in the Diocese of Uganda[4] with delegated oversight for all of Ruanda-Urundi (a "suffragan area");[5] he was based in Ibuye (now in Burundi).[6] When the Diocese of Ruanda-Urundi was erected (from Uganda diocese) in 1960, Brazier became her first diocesan bishop.[7] Brazier retired in 1964 and was succeeded by Lawrence Barham, part of whose brief was to prepare the diocese for division: as part of this process, Yohana Nkunzumwami, Archdeacon of Northern Burundi, was appointed Assistant Bishop in Burundi[8] and was the first Burundian consecrated a bishop.[9] He became the first diocesan bishop of all Burundi when that diocese was erected in 1966;[10] by the time of his death in post in 1978, his See was that of Buye.[11]
