Roman Catholic Archdiocese of Kinshasa
On 3 April 1919, it was renamed the Apostolic Vicariate of Léopoldville. It lost territory several times more: to establish the "Mission sui juris" of Bikoro on 3 January 1931, the Apostolic Vicariate of Boma on 26 February 1934, the Apostolic Prefecture of Kole on 14 June 1951, and the Apostolic Vicariate of Inongo on 29 June 1953. It was elevated on 10 November 1959 as the Archdiocese of Léopoldville, when the city was soon to become the national capital of the newly-independent Republic of the Congo. It was renamed the Archdiocese of Kinshasa on 30 May 1966, when the city's name was changed from Léopoldville to Kinshasa. The archdiocese was visited by Pope John Paul II in May 1980 and again in August 1985.
The Archdiocese of Kinshasa is the metropolitan archdiocese of the Ecclesiastical Province of Kinshasa, which includes the following suffragan dioceses:
Kingdom of Kongo
Álvaro also worked hard to westernize Kongo, gradually introducing European style titles for his nobles, so that the Mwene Nsundi became the Duke of Nsundi; the Mwene Mbamba became the Duke of Mbamba. The Mwene Mpemba became Marquis of Mpemba, and the Mwene Soyo became Count of Soyo. He and his son Álvaro II Nimi a Nkanga (crowned in 1587) bestowed orders of chivalry called the Order of Christ. The capital was also renamed São Salvador or "Holy Savior" in Portuguese during this period. In 1596, Álvaro's emissaries to Rome persuaded the Pope to recognize São Salvador as the cathedral of a new diocese which would include Kongo and the Portuguese territory in Angola. However, the king of Portugal won the right to nominate the bishops to this see, which became a source of tension between the two countries.
