The Holstein troops belonged territorially to the equal Duchy of Schleswig-Holstein and the Russian Empire. This unity is fully reflected in the symbolism of the banners and regimental emblems. The composition of the regiments was multinational and included representatives of dozens of nationalities from Europe, Russia and even Asia, including Austrians and Swedes, Karelians and Finns, Russians and Ukrainians, Poles and Serbs, Kalmyks and Persians, which is significant - they got along with each other without problems under the command of Holstein officers, among whom there were also people of various nationalities. During the palace coup of 1762, when power was seized by the wife of Peter III, the future Russian Empress Catherine II, the Holsteiners were ready to die in order to protect their emperor. However, the monarch's indecisiveness led to his defeat. The Oranienbaum Guard was disbanded, forever erasing the memory of the military amusements of the Holstein prince.A number of historians suggest that court architect Antonio Rinaldi and chief architect Bartelomeo Rastrelli took part in the development of the Holstein uniform.
