It was Pope Julius II that founded the Swiss Guards in 1506. Often dubbed as "the world's smallest army", the Swiss guards - a separate entity to the Swiss Armed Forces - are hired by the Roman Catholic Church, under the leadership of the pope, to whom they swear loyalty in a ceremony at the Belvedere Court in the Vatican.
This ceremony takes place every year on 6 May - to mark the anniversary of the Sack of Rome in 1527, in which over 150 Swiss Guards were killed defending Pope Clement VII - who escaped to neighbouring Castel Sant'Angelo, escorted by the remaining 22 guards.
It is said that during the Middle Ages, Switzerland gained a reputation for having the most reliable mercenaries in Europe. Then Pope, Julius II, who had long admired the Swiss soldiers who defended the King of France, requested 200 Swiss mercenaries of his own to use as bodyguards and to defend his palaces. After months of marching, 150 swiss guards arrived in Rome on 21 January, 1506 to serve the Pope.

Along with the Pontifical Gendarmerie, the Swiss Guards are responsible for ensuring the safety of the Pope both within and outside the Vatican and for accompanying Pope Francis as he moves around among the people.
