2 Zlotys Polskie - Nikolai I

Issued under the constitutional Kingdom of Poland, a nominally autonomous state under Russian imperial control established at the Congress of Vienna in 1815, these coins reflect the uneasy dual sovereignty of the period — Nikolai I ruled simultaneously as Tsar of Russia and King of Poland under a separate Polish constitution. That arrangement collapsed entirely with the November Uprising of 1830, which began just as this series was ending. Warsaw Mint production halted, and post-rebellion coinage was reissued under openly Russian imperial authority with the constitutional fiction abandoned.
