Arguing that the revolution needed not a mere parliamentary organization but a party of action which would function as a scientific body of direction, a vanguard of activists, and a central control organ, the Tenth Party Congress banned factions within the party, initially intending it only to be a temporary measure after the shock of the Kronstadt rebellion. It was also argued that the party should be an elite body of professional revolutionaries dedicating their lives to the cause and carrying out their decisions with iron discipline, thus moving toward putting loyal party activists in charge of new and old political institutions, army units, factories, hospitals, universities, and food suppliers. Against this backdrop, the "nomenklatura" system (a class of people who were granted key positions only with approval of the party) would evolve and become standard practice.
