The Russian state also continued to support serfdom due to military conscription. The conscripted serfs dramatically increased the size of the Russian military during the war with Napoleon. With a larger military Russia achieved victory in the Napoleonic Wars and Russo-Persian Wars; this did not change the disparity between Russia and Western Europe, who were experiencing agricultural and industrial revolutions. Compared to Western Europe it was clear that Russia was at an economic disadvantage. European philosophers during the Age of Enlightenment criticized serfdom and compared it to medieval labor practices which were almost non-existent in the rest of continent. Most Russian nobles were not interested in change toward western labor practices that Catherine the Great proposed. Instead they preferred to mortgage serfs for profit. Napoleon did not touch serfdom in Russia. What the reaction of the Russian peasantry would have been if he had lived up to the traditions of the French Revolution, bringing liberty to the serfs, is an intriguing question. In 1820, 20% of all serfs were mortgaged to state credit institutions by their owners. This was increased to 66% in 1859.
