The Polish May 3rd Constitution of 1791, second only after America

The Polish May 3rd Constitution was the second modern constitution to come into force in world history. The Americans were first in 1789 but the Poles did manage to beat the French to second place by exactly 3 months. The May 3rd Constitution was the last attempt by king Stanisław August Poniatowski to save Poland from becoming completely dominated by foreign powers, and particularly by the Russian Empire.
