The Bank of Prussia (German: Preußische Bank) was the central bank of the Kingdom of Prussia. It was originally founded by Frederick the Great in 1765-1766 as the state-owned Prussian Royal Bank (German: Königliche Giro- und Lehnbank or Königliche Hauptbank). In 1847, it was reorganized as a formally private-sector entity and renamed the Bank of Prussia. It operated until 1 January 1876, when it was succeeded by the newly created Reichsbank.
