This military unit has been guarding the Pope without a break for over 500 years
The Vatican Swiss Guard is primarily regarded as a tourist attraction, but they are actually descended from a famous military tradition and their duties are anything but just ceremonial.
Composed of a company of former Swiss military, the Swiss Guard are responsible for the protection of the Pope and perform many ceremonial functions as well. Though best known for their colorful uniforms and halberds, plainclothes Guardsmen also serve as bodyguards for the Pope and security for the Vatican.
Entrance requirements for the Guard is strict. Potential Guardsmen must be Catholic males, of Swiss nationality, and have completed Swiss military training. Their service records have to be spotless, and they must be at least 5' 9" tall and be between 19 and 30 years of age. Though the Guard has considered opening up positions for women, for now it's exclusively male.
The Guard's history stretches back to the Middle Ages. Swiss mercenaries, or Reislaufer, were among the most feared fighting forces of the late Middle Ages and Renaissance. Switzerland was an overpopulated and poor country, and its independent cantons would contract out its militia to other countries as a means of support.
Gaining their reputation with spectacular victories over their Austrian Habsburg overlords in the 13th century, the Swiss were famed for their skill in using pikes and halberds in deep column attacks. Their general refusal to take prisoners only added to their ferocious repute, and they became the most prized mercenaries in Europe.
Noted for their loyalty, Swiss mercenaries served as the bodyguard contingent for many European monarchs such as the French throne. During the storming of the Louis XVI's palace during the French Revolution, his Swiss Guard refused to surrender despite being hopelessly outnumbered and running low on ammunition. It took a note from the king himself for them to lay down their arms, and their spirited defense so enraged the revolutionaries hundreds of them were summarily executed.
Swiss mercenaries had been serving the Papal States for centuries, but it wasn't until 1506 that a permanent Guard of 150 men under the direct control of the Pope was formed, at the suggestion of the Swiss bishop Matthaus Schiner. When mutinous unpaid troops from the Holy Roman Empire sacked Rome in 1527, the Swiss Guard proved their bravery by losing most of their number defending Pope Clement VII. Out of 189 men, only 42 survived, but they bought time for the Pope to escape through a secret tunnel ahead of marauding enemy soldiers hoping to hold him for ransom.
When German forces occupied Rome during World War II, the Guard took up defensive positions and prepared to fight to the death, but Adolf Hitler chose not to attack the Vatican.
The Guard gradually morphed into a mostly ceremonial unit during the later 20th century, but this changed with the assassination attempt on Pope John Paul II in 1981. Mehmet Agca, a Turkish national believed to have been backed by the KGB, shot the Pope four times as he entered St. Peters Square, nearly killing him. The Guard has since refocused as personal protection, with the pope's security detail beefed up and armed with light automatic weapons.
In 2006, the Guard celebrated its 500th anniversary by marching a contingent of former Guardsmen from Bellinzona in southern Switzerland to Rome, in emulation of the first Guards journey in 1505-06. Since Switzerland banned mercenaries in 1874 with the sole exception of the Vatican, this unit is the last remaining example of a storied line of soldiers.
