10 Zlotys Wojciech Korfanty

Korfanty remains a genuinely contested figure in Polish historiography. He organized and led the Third Silesian Uprising of 1921 — an armed insurrection against German control of Upper Silesia following a plebiscite result that had gone against Polish annexation — without formal authorization from Warsaw, which spent much of the uprising nervously distancing itself from him to avoid provoking Germany. The League of Nations ultimately partitioned Silesia in Poland's favor, a decision that owed more to Korfanty's military pressure than to the ballot.

He died in 1939, weeks after being released from Carthaus prison, where the Sanacja government had held him without trial.
