  The tsar was responsible for numerous other reforms including reorganizing the judicial system , setting up elected local judges , abolishing capital punishment , promoting local self - government through the zemstvo system , imposing universal military service , ending some of the privileges of the nobility , and promoting the universities .
  Despite these reforms , during his reign , his brutal secret police , known as the Third Section , sent thousands of dissidents into exile in Siberia .
  In foreign policy , Alexander sold Alaska to the United States in 1867 , fearing the remote colony would fall into British hands if there was another war .
  He sought peace , moved away from bellicose France when Napoleon III fell in 1871 , and in 1872 joined with Germany and Austria in the League of the Three Emperors that stabilized the European situation .
  Despite his otherwise pacifistic foreign policy , he fought a brief war with Turkey in 1877 - 78 , pursued further expansion into Siberia and the Caucasus , and conquered Turkestan .
  Although disappointed by the results of the Congress of Berlin in 1878 , Alexander abided by that agreement .
  Among his greatest domestic challenges was an uprising in Poland in 1863 , to which he responded by stripping that land of its separate Constitution and incorporating it directly into Russia .
