Why Alexander 11 of Russia called an uneffective leader​

Alexander II, Russian in full Aleksandr Nikolayevich, (born April 29 [April 17, Old Style], 1818, Moscow, Russia—died March 13 [March 1], 1881, St. Petersburg), emperor of Russia (1855–81). His liberal education and distress at the outcome of the Crimean War, which had demonstrated Russia’s backwardness, inspired him toward a great program of domestic reforms, the most important being the emancipation (1861) of the serfs. A period of repression after 1866 led to a resurgence of revolutionary terrorism and to Alexander’s own assassination.
