Pope John Paul II, born Karol Jozef Wojtyla, was ordained in 1946, and in 1978, became the first Polish pope and first non-Italian Pope in more than 400 years. He served as head of the Catholic Church until his passing in 2005. Beatified by Pope Benedict XVI in 2011, he was canonized by Pope Francis in 2014. That same year, BBC broadcaster Edward Stourton was ushered into a room in one of Europe's most celebrated libraries. Watched over by it's director, he was shown a pile of papers so sensitive that only a handful of staff knew of their existence. He was looking at a collection of hundreds of personal letters between Pope John Paul II and a Polish American woman, Anna-Theresa Tymieniecka.
