On 28 April 2021 the National Bank of Poland presented a new coin minted to commemorate the 230th anniversary of the 3rd of May Constitution. The 3rd of May Constitution was adopted on 3 May 1791. It regulated the legal system of the Polish-Lithuanian Commonwealth. It is generally accepted that the 3rd of May Constitution was the first modern written constitution in Europe and the second one in the world (after the American Constitution of 1787). It was adopted by King Stanisław August Poniatowski. It was designed to eliminate long-standing flaws in the political system of the Polish-Lithuanian Commonwealth based on free election and the democracy of the nobility. The constitution changed the state's system to a hereditary monarchy, significantly limited the democracy of the nobility by removing the right to vote and decide on matters of state from the landless nobility, introduced partial equality between the personal rights of the bourgeoisie and the nobility, and placed the peasants under state protection, thus mitigating the abuse of serfdom. The constitution formally abolished the liberum veto. The reverse of the gold coin features the coat of arms of the Kingdom of Poland (the official name of the state at the time) from the days of Stanisław August, consisting of the White Eagle under the regal crown (coat of arms of the Polish Crown), Vytis (coat of arms of the Grand Duchy of Lithuania), and Ciołek (coat of arms of the House of Poniatowski). A visible ribbon with the motto: Pro fide, lege et grege, meaning: For faith, justice, and the nation. At the bottom, the cross of the highest state decoration – the Order of the White Eagle
