why do swiss guards guard the vatican

The Swiss Guards guard the Vatican because they serve as the personal protectors of the Pope and the Apostolic Palace, a tradition that started in 1506 under Pope Julius II. Swiss mercenaries were historically renowned for their military professionalism and were often hired as elite bodyguards for monarchs across Europe. The Vatican chose Swiss soldiers to protect the Pope due to their reputation, discipline, and military skills, and this tradition has continued for over 500 years. Their role includes not only ceremonial duties but also modern security tasks to protect the Pope from contemporary threats. The Swiss Guard is considered the world's smallest army and remains a symbol of loyalty, discipline, and historical continuity within the Vatican City State.
