In 1707, Apostol Kigetsch, a Wallachian nobleman serving Russian Emperor Peter the Great, was given the task to form a "khorugv" ("banner" or "squadron") of 300 men to serve on the Ottoman-Russian border. The squadron consisted of Christians from Hungary, Serbia, Moldavia, and Wallachia. In 1711, prior to the Pruth campaign, 6 regiments (4 khorugv's each) of hussars were formed, mainly from Wallachia. Two other 'khorugv', for guerilla warfare, were formed, one Polish and one Serbian, to battle the Ottomans. In 1723, Peter the Great formed a Hussar regiment exclusively from Serbian light cavalry serving in the Austrian army. On 14 October 1741, during the regency of Grand Duchess Anna Leopoldovna, four Hussar regiments, a Serbian ("Serbskiy"), a Moldavian ("Moldavskiy"), a Hungarian ("Vengerskiy") and a Georgian ("Gruzinskiy") were authorized.
