Swiss Guards are Swiss mercenary soldiers who have served as bodyguards, ceremonial guards, and palace guards at foreign European courts from the late 15th century until the present day (in the form of the Papal Swiss Guard). They have generally had a high reputation for discipline and loyalty to their employers. Some of these units have also served as fighting troops in the field. There were also regular Swiss mercenary regiments serving as line troops in various armies, notably those of France, Spain and Naples until the 19th century who were not household or guard units.
Various "Swiss Guards" have existed. The earliest such detachment was the Swiss "Hundred Guard" (Cent-Garde) at the French court (1497 � 1830). This small force was complemented in 1567 by a Swiss Guard regiment. The Papal Swiss Guard in the Vatican was founded in 1506 and is the only Swiss Guard that still exists. In the 18th century several other Swiss Guards existed for periods in various European courts.
This is unrelated to the Sovereign Military Order of Malta, which is the third sovereign state within Rome.
