A trabant (Ital. trabanti, from the German traben, Lat.: satellites) was a historical name for an attendant, Leibgarde (en: life guard), especially in the Middle Ages, who usually travelled on foot (as opposed to horseback). The role of a trabant was to protect a member of the aristocracy, a senior official or a senior Landsknecht officer, or to carry out their orders. For a long time it was customary for them to dress in short white hose and a waistcoat in the Spanish style. In earlier times they were armed with a halberd and a dagger. Later they were also used as cavalry.
The trabant guards frequently formed the core of household troops or, as in Brandenburg, field troops as well. The Gardes du Corps were formed from the 2 companies of trabants serving the Electorate of Brandenburg's grand elector, who fought with him in 1675 at the Battle of Fehrbellin.
In the order of battle in 1682 for the newly created Saxon Army there were 172 horses listed in the Trabant Horse Guards (Trabanten-Leibgarde zu Roß) as well as 65 men in the Trabant Foot Guards (Leibgarde der Fuß-Trabanten). In 1701, the Saxon Gardes du Corps was formed out of the Saxon trabants. This Saxon regiment met its end in Napoleon's 1812 Russian campaign. In the endless march on Moscow and the subsequent retreat, almost all the trabants lost their lives. The Elector did not reinstate this guards regiment.
