10 Lei Ion I. C. Brătianu

Ion I. C. Brătianu served as Romania's dominant political figure during and after the First World War, negotiating the 1916 Treaty of Bucharest with the Entente powers that brought Romania into the war on terms promising substantial territorial gains — including Transylvania, Bukovina, and parts of Hungary. When the Paris Peace Conference convened in 1919, he proved a notoriously difficult negotiator, ultimately securing most of those promised territories through the Treaty of Trianon in 1920.

This issue belongs to Romania's long-running .999 silver commemorative program administered by the National Bank, which has systematically honored figures central to the formation of Greater Romania after 1918.
