Royal Guards (Polish–Lithuanian Commonwealth)
The Royal Guards, also known as the Royal Foot Guards (Polish: Gwardia Piesza Koronna), were the royal guard units of the military of the Polish–Lithuanian Commonwealth, which existed from 1569 to 1795. Charged with the protection of Poland-Lithuania's royal family, they formed either part of the Polish Crown Army or the Grand Ducal Lithuanian Army, and fought in numerous conflicts Poland-Lithuania participated in during the early modern period.
