Swiss Guard

The Pontifical Swiss Guard, also known as the Papal Swiss Guard or simply Swiss Guard, is an armed forces, guard of honour, and protective security unit, maintained by the Holy See to protect the Pope and the Apostolic Palace within the territory of the Vatican City State. Established in 1506 under Pope Julius II, it is among the oldest military units in continuous operation and is sometimes called "the world's smallest army".

The Swiss Guard is recognised by its Renaissance-era dress uniform, consisting of a tunic striped in red, dark blue, and yellow; high plumed helmet; and traditional weapons such as the halberd. Guardsmen perform their protective duties in functional attire and with modern firearms. Since the assassination attempt on Pope John Paul II in 1981, the Guard has placed greater emphasis on its nonceremonial roles and has sought more training in anti-irregular military counterintelligence, commando-style raids, counter-sniper tactics, counterterrorism, close-quarters battle, defusing and disposal of bombs, executive protection, hostage rescue, human intelligence, medical evacuation, reconnaissance, tactical driving, tactical medical services, and tactical fast shooting by small arms.

The Swiss Guard is considered an elite military unit. It is highly selective in its recruitment: candidates must be unmarried Swiss Catholic males between 19 and 30 years of age and at least 5 feet 8.5 inches (1.74 meters), who have completed basic training with the Swiss Armed Forces and hold a professional diploma or high school degree. As of 2024, there were 135 members.

The Swiss Guard's security mission extends to the Pope's apostolic travels, the pontifical palace of Castel Gandolfo, and the College of Cardinals when the papal throne is vacant. Though the Guard serve as watchmen of Vatican City, the overall security and law enforcement of the city-state is conducted by the Corps of Gendarmerie of Vatican City, which is a separate body.

The Pontifical Swiss Guard has its origins in the 15th century. Pope Sixtus IV (1471–1484) had allied with the Swiss Confederacy and built barracks in Via Pellegrino after foreseeing the possibility of recruiting Swiss mercenaries. The pact was renewed by Pope Innocent VIII (1484–1492) in order to use Swiss troops against the Duke of Milan. Alexander VI (1492–1503) later used the Swiss mercenaries during his alliance with the King of France.

During the time of the Borgias, the Italian Wars began, in which the Swiss mercenaries were a fixture on the front lines among the warring factions, sometimes for France, and sometimes for the Holy See or the Holy Roman Empire. The mercenaries enlisted when they heard King Charles VIII of France was going to war with Naples. Among the participants in the war against Naples was Cardinal Giuliano della Rovere, the future Pope Julius II (1503–1513), who was well acquainted with the Swiss, having been Bishop of Lausanne years earlier.^{[citation needed]}

The expedition failed, in part thanks to new alliances made by Alexander VI against the French. When Cardinal della Rovere became Pope Julius II in 1503, he asked the Swiss Diet to provide him with a constant corps of 200 Swiss mercenaries. This was made possible through financing by German merchants from Augsburg, Ulrich, and Jacob Fugger, who had invested in the Pope and saw fit to protect their investment.

In September 1505, the first contingent of 150 soldiers departed on foot to Rome, under the command of Kaspar von Silenen. They entered the city on 22 January 1506, now regarded as the official date of the Guard's foundation.
