Passage: For administration, Russia was divided (as of 1914) into 81 governorates (guberniyas), 20 oblasts, and 1 okrug. Vassals and protectorates of the Russian Empire included the Emirate of Bukhara, the Khanate of Khiva and, after 1914, Tuva (Uriankhai). Of these 11 Governorates, 17 oblasts and 1 okrug (Sakhalin) belonged to Asian Russia. Of the rest 8 Governorates were in Finland, 10 in Poland. European Russia thus embraced 59 governorates and 1 oblast (that of the Don). The Don Oblast was under the direct jurisdiction of the ministry of war; the rest had each a governor and deputy-governor, the latter presiding over the administrative council. In addition there were governors-general, generally placed over several governorates and armed with more extensive powers usually including the command of the troops within the limits of their jurisdiction. In 1906, there were governors-general in Finland, Warsaw, Vilna, Kiev, Moscow, and Riga. The larger cities (Saint Petersburg, Moscow, Odessa, Sevastopol, Kerch, Nikolayev, Rostov) had an administrative system of their own, independent of the governorates; in these the chief of police acted as governor.
