Russian oblast', from Old Church Slavonic oblastĭ : ob, on; + vlastĭ, power.(American Heritage® Dictionary of the English Language, Fourth Edition)
From a Slavic language, probably Russian область (óblast’, "region, province"), borrowed from Old Church Slavonic область (oblast’), from Proto-Slavic *obolstь, from earlier Proto-Slavic *obvolstь, *obvoldtь, a compound of *o(b)- (“over”) + *volstь (“rule, power, authority”), thus originally probably meaning "a region ruled over". Compare Proto-Slavic *obvoldati (“to rule”). (Wiktionary)
