The Vatican has Swiss Guards because the Pontifical Swiss Guard was established in 1506 by Pope Julius II to serve as an elite protective force for the Pope and the Vatican. The Swiss were chosen because Swiss mercenaries were renowned as some of the best soldiers in Europe at the time, known for their discipline, loyalty, and military skill. The Swiss Guard's primary mission is to protect the Pope, the Apostolic Palace, and other Vatican properties. This tradition began when a contingent of 150 Swiss soldiers entered Rome to serve as the Pope’s personal guard, and the unit has continued for over 500 years, surviving many historical challenges including the famous defense of the Pope during the Sack of Rome in 1527, where most of the Guards died defending Pope Clement VII. Today, the Swiss Guards still perform ceremonial duties and provide security for the Pope, including during his travel, and they are highly trained in various protective and tactical disciplines. The Swiss Guard remains a symbol of loyalty and protection for the Vatican, rooted in this long history and tradition.
