On August 6, 1978, Paul VI died after a 15-year papacy that included issuing Humanae Vitae and all that came with it. His successor, Pope John Paul I (Cardinal Albino Luciani), was quickly elected — and then after only 33 days as pope. The conclave following his death would end with the election of one of the most influential and important popes in the history of the Church, Pope St. John Paul II.
