Leibgarde (also life-guard, or household troops) has been, since the 15th century, the designation for the military security guards who protected Fürsten (royals and nobles) — usually members of the highest nobility who ruled over states of the Holy Roman Empire and later its former territory — from danger. The Leibgarde should not be mixed up with bodyguard (Leibwächter), which may refer also to a single private individual.
