5. May Constitution, 1791
The Polish Constitution of May 3, 1791 (Polish: Konstytucja Trzeciego Maja) was Europe's first modern codified national constitution. It was instituted by the Government Act (Polish: Ustawa rządowa) adopted on that date by the Sejm (parliament) of the Polish-Lithuanian Commonwealth. It was designed to redress long-standing political defects of the federative Polish-Lithuanian Commonwealth and its Golden Liberty. The Constitution introduced political equality between townspeople and nobility (szlachta) and placed the peasants under the protection of the government,[1] thus mitigating the worst abuses of serfdom. The Constitution abolished pernicious parliamentary institutions such as the liberum veto, which at one time had placed the sejm at the mercy of any deputy who might choose, or be bribed by an interest or foreign power, to undo all the legislation that had been passed by that sejm. The May 3rd Constitution sought to supplant the existing anarchy fostered by some of the country's reactionary magnates, with a more egalitarian and democratic constitutional monarchy.
