This chapter covers the developments prior to 1801, the Imperial Army during the reign of Alexander I, the origins and programmes of the revolutionary ‘military intelligentsia’ from 1815 to 1825; the Caucasus Corps and the Second Army during 1816 to 1825; the character and policy of Nicholas I and the struggle against the ‘Russian Party’. The regime's belief in the existence of a Russian party certainly aids in understanding tsarist Eastern policy under Nicholas. On one hand, the regime attempted to defuse nationalist passions by presenting the war as a dispute between two courts. Alternatively, the domestic benefits of a forward Eastern policy were well understood. By leading his troops to a short and glorious war, Nicholas could enhance his image and deliver a public rebuke to Metternich.
