1 Rouble Konstantin Ostrozhsky

Konstantin Ostrozhsky — Hetman of Lithuania and one of the most successful military commanders in early sixteenth-century Eastern Europe — is credited with defeating a Muscovite army of roughly 80,000 at the Battle of Orsha in 1514, a victory celebrated across Catholic Europe as a check on Russian expansion. Belarus has periodically claimed figures from the Grand Duchy of Lithuania as part of its own national historical narrative, and this issue sits squarely within that project.

KM#476 is part of a broader commemorative rouble series the National Bank issued through the 2010s in copper-nickel, intended for circulation-grade collecting rather than precious metal markets.
