The missions in Burundi had been under the
Apostolic Vicariate of Unyanyembe, while those of Rwanda were under the
Apostolic Vicariate of Southern Victoria Nyanza. In 1912 these missions were joined to form the new Apostolic Vicariate of Kivu. On 12 December 1912,
John Joseph Hirth was appointed the first Vicar Apostolic of Kivu. Hirth established his headquarters at
Kabgayi, and worked there until his retirement in 1921. By then there were thirty thousand Christians in the Vicariate. The name was changed to the Apostolic Vicariate of Urundi and Kivu in 1921. On 25 April 1922 the
Apostolic Vicariate of Ruanda was created from the former Apostolic Vicariate of Kivu, led by Bishop
Léon-Paul Classe. On 14 February 1952 this was divided into the
Apostolic Vicariate of Kabgayi and the
Apostolic Vicariate of Nyundo. The
Apostolic Vicariate of Urundi was also created on 25 April 1922, serving the territory of what is now
Burundi and led by Bishop
Julien-Louis-Edouard-Marie Gorju. On 14 July 1949 it was renamed to the Apostolic Vicariate of Kitega, and on 10 November 1959 was elevated to the
Archdiocese of Gitega. ==Congo==
