She also gave away 66,000 serfs in 1762–72, 202,000 in 1773–93, and 100,000 in one day: 18 August 1795. Thus she was able to bind the nobility to herself. From 1782, a kind of uniform was introduced for civilian nobles called uniform of civilian service or simply civilian uniform. The uniform prescribed colors that depended on the territory. The uniform was required at the places of service, at the Court, and at other important public places. The privileges of the nobility were fixed and were legally codified in 1785 in the Charter to the Gentry. The Charter introduced an organization of the nobility: every province ("guberniya") and district ("uyezd") had an Assembly of Nobility. The chair of an assembly was called Province/District Marshal of Nobility. In 1831 Nicholas I restricted the assembly votes to those with over 100 serfs, leaving 21,916 voters.
