Pope Paul VI (born Giovanni Battista Enrico Antonio Maria Montini; 26 September 1897 – 6 August 1978) was head of the Catholic Church and sovereign of the Vatican City State from 21 June 1963 until his death on 6 August 1978. Succeeding John XXIII, he continued the Second Vatican Council, which he closed in 1965, implementing its numerous reforms.

He fostered improved ecumenical relations with Eastern Orthodox and Protestant churches, which resulted in many historic meetings and agreements. In January 1964, he flew to Jordan, the first time a reigning pontiff had left Italy in more than a century. Montini served in the Holy See's Secretariat of State from 1922 to 1954, and along with Domenico Tardini was considered the closest and most influential advisor of Pope Pius XII.
