The establishment of the Table of Ranks was among the most audacious of Peter's reforms, a direct blow to the power of the Boyars which changed Russian society significantly. Previously, high-ranking state positions were hereditary, but with the establishment of the Table of Ranks, anyone, including a commoner, could work their way up to the bureaucratic hierarchy with sufficient hard work and skill. A new generation of technocrats soon supplanted the old Boyar class and dominated the civil service in Russia. With minimal modifications, the Table of Ranks remained in effect until the Russian Revolution of 1917.
