Swiss Guards are Swiss soldiers who have served as guards at foreign European courts since the late 15th century. The earliest Swiss Guard unit to be established on a permanent basis was the Hundred Swiss (Cent-Suisses), which served at the French court from 1490 to 1817. This small force was complemented in 1616 by a Swiss Guards regiment. In the 18th and early 19th centuries several other Swiss Guard units existed for periods in various European courts.
