The earliest history of the accordion in Russia is poorly documented. Nevertheless, according to Russian researchers, the earliest known simple accordions were made in Tula, Russia by Timofey Vorontsov from 1820, and Ivan Sizov from 1830. By the late 1840s, the instrument was already very widespread;[14] together the factories of the two masters were producing 10,000 instruments a year. By 1866, over 50,000 instruments were being produced yearly by Tula and neighbouring villages, and by 1874 the yearly production rate was over 700,000. By the 1860s, Novgorod, Vyatka and Saratov Governorates also had significant accordion production. By the 1880s, the list included Oryol, Ryazan, Moscow, Tver, Vologda, Kostroma, Nizhny Novgorod, Simbirsk and others, and many of these places created their own varieties of the instrument.
