The Russian nobility or dvoryanstvo (Russian: дворянство) arose in the Middle Ages. In 1914, it consisted of approximately 1,900,000 members, out of a total population of 138,200,000.[1] Up until the February Revolution of 1917, the Russian noble estates staffed most of the Russian government and possessed a self-governing body, the Assembly of the Nobility.
The Russian word for nobility, dvoryanstvo derives from Slavonic dvor (двор), meaning the court of a prince or duke (knyaz), and later, of the tsar or emperor. Here, dvor originally referred to servants at the estate of an aristocrat. In the late 16th and early 17th centuries, the system of hierarchy was a system of seniority known as mestnichestvo. The word dvoryane described the highest rank of gentry, who performed duties at the royal court, lived in it (Moskovskie zhiltsy, "Moscow dwellers"), or were candidates to it, as for many boyar scions (dvorovye deti boyarskie, vybornye deti boyarskie). A nobleman is called a dvoryanin (plural: dvoryane). Pre-Soviet Russia shared with other countries the concept that nobility connotes a status or social category rather than a title. Throughout the 18th and 19th centuries, the title of the nobleman in Russia gradually became a formal status, rather than a reference to a member of the aristocracy, due to a massive influx of commoners via the Table of ranks.
Many descendants of the former ancient Russian aristocracy, including royalty, saw their formal standing change to merchants, burghers, or even peasants, while people descended from serfs (like Vladimir Lenin's father) or clergy (like in the ancestry of actress Lyubov Orlova) gained formal nobility.
