Word Originlate 15th century: from Old French aristocratie, from Greek aristokratia, from aristos ‘best’ + -kratia ‘power’. The term originally denoted the government of a state by its best citizens, later by the rich and well born, hence the sense ‘nobility’, regardless of the form of government (mid 17th century).
