The Bolgar Historical and Archaeological Complex is a unique evidence of the strong early medieval states of Volga Bulgaria and the Golden Horde existence. The civilization vanished jointly with this states in the 16th century but determined the features of religion, culture, customs and traditions for the inhabitants of this region and gave birth to the modern Tatar ethnos, which is Russia’s second largest one, and to other nations of the Volga-Urals region. At present, the Bolgar Historical and Archaeological Complex is the only real trace proving the existence of Volga Bolgaria and the Golden Horde in its flowering.
The spatial layout of the complex is a great example of advanced urbanism in Eurasia, which is one of the major signs of civilization. Other civilizational features include coin-minting, coin circulation and the development of the monetary-weight system. In the 10th century and in 1240-1330, silver and copper coins were minted in Bolgar. The development of international, interregional and inland trade, cultural cooperation and cultural symbiosis of settled and nomadic nations are well seen through archaeological discoveries dating back to the 10th-15th centuries.
