Pope Paul VI (Latin: Paulus VI; Italian: Paolo VI), born Giovanni Battista Enrico Antonio Maria Montini, reigned from 21 June 1963 to his death in 1978. Succeeding John XXIII, he continued the Second Vatican Council which he closed in 1965, implementing its numerous reforms, and fostered improved ecumenical relations with Eastern Orthodox and Protestants, which resulted in many historic meetings and agreements. Montini served in the Holy See's Secretariat of State from 1922 to 1954. While in the Secretariat of State, Montini and Domenico Tardini were considered as the closest and most influential advisors of Pope Pius XII, who in 1954 named him Archbishop of Milan, the largest Italian diocese. Montini later became the Secretary of the Italian Bishops' Conference. John XXIII elevated him to the College of Cardinals in 1958, and after the death of John XXIII, Montini was considered one of his most likely successors.
Upon his election to the papacy, Montini took the name Paul VI. He re-convened the Second Vatican Council, which had automatically closed with the death of John XXIII. After the Council had concluded its work, Paul VI took charge of the interpretation and implementation of its mandates, often walking a thin line between the conflicting expectations of various groups within Catholicism. The magnitude and depth of the reforms affecting all fields of Church life during his pontificate exceeded similar reform programmes of his predecessors and successors. Paul VI spoke repeatedly to Marian conventions and mariological meetings, visited Marian shrines and issued three Marian encyclicals. Following his famous predecessor Saint Ambrose of Milan, he named Mary as the Mother of the Church during the Second Vatican Council.
Following the standard procedures that lead to sainthood, Pope Benedict XVI declared that the late pontiff had lived a life of heroic virtue and conferred the title of Venerable upon him on 20 December 2012. Pope Francis beatified him on 19 October 2014 after the recognition of a miracle attributed to his intercession. His liturgical feast is celebrated on the date of his birth on 26 September.
Popes John Paul I, John Paul II, and Benedict XVI were made cardinals during his papacy.
