Seima-Turbino refers to burial sites dating around 1500 BC found across northern Eurasia, from Finland to Mongolia. The buried were nomadic warriors and metal-workers, travelling on horseback or two-wheeled chariots. These nomads originated from the Altai Mountains. Although they were the precursor to the much later Mongol invasions, these groups were not yet strong enough to attack the important social sites of the Bronze Age.[1]
