At the 2010 census, Tula had a population of 501,169, an increase from 481,216 in 2002, making it the 32nd largest city in Russia by population. A primarily industrial city, Tula was a fortress at the border of the Principality of Ryazan.

The Demidov family built the first armament factory in Russia in the city, in what would become the Tula Arms Plant, which still operates to this day. More information...
