5 Pyadey Ataman Yermak Timofeevich; eagle of Ivan IV the Terrible

Yermak Timofeevich led the Cossack conquest of Siberia beginning in 1581 under a campaign partly financed by the Stroganov merchant family, pushing beyond the Ural Mountains against the Siberian Khanate of Kuchum. His campaign delivered an enormous territorial claim to Ivan IV, though Yermak himself drowned in the Irtysh River in 1585 — reputedly weighed down by the coat of armor the Tsar had gifted him.
