Gibraltar-Vatican Joint Issue
The Vatican City State issued its first stamps in 1929, the same year that it was established under the Lateran Treaties. It released its first joint issue in 1969. Joint issues of stamps by the Vatican and other countries were uncommon for most of the twentieth century. In 2000, the Vatican and Poland released a joint issue designed by Czeslaw Slania which commemorated the eightieth birthday of John Paul II. However, the early twenty-first century saw a substantial increase in joint issues. In 2003, a set released by the Vatican and Poland celebrated the twenty-fifth anniversary of John Paul II's pontificate. The following year, a joint issue of the same countries commemorated the pope's return visits to Poland. In 2005, five of the eleven stamp sets released by the Vatican were joint issues. There have also been joint issues with Germany since Benedict XVI became Pope. In 2011, the Vatican and Croatia released a joint issue which commemorated the tercentenary of the birth of Rugerius Boscovich (1711 – 1787).
Pope
The apostolic see of Rome was founded by Saint Peter and Saint Paul in 1st century, according to Catholic tradition. The papacy is one of the most enduring institutions in the world and has had a prominent part in world history. In ancient times the popes helped spread Christianity, and intervened to find resolutions in various doctrinal disputes. In the Middle Ages, they played a role of secular importance in Western Europe, often acting as arbitrators between Christian monarchs. Currently, in addition to the expansion of the Christian faith and doctrine, the popes are involved in ecumenism and interfaith dialogue, charitable work, and the defense of human rights.
