20 Roubles Sophia of Galshany

Sophia of Halshany — the fourth wife of Władysław II Jagiełło — is remembered less for her own reign than for producing the male heir, Władysław III, that the Jagiellonian dynasty had spent decades waiting for. She outlived her husband by over two decades, wielding considerable influence at the Lithuanian-Polish court through the mid-15th century. Belarus has claimed her as part of its medieval heritage largely through the ruins of Halshany Castle, built by her family in the Grand Duchy of Lithuania.
