Stanislaw Augustus (1732-1798) was the last Polish king. Not without controversy, he was one of the greatest patrons of the arts and sciences in his day. In his many efforts, he supported publishing, libraries, architecture, education, painting, cartography, ballet, theater, and industry. He was also the co-author of the Polish constitution of May 3, 1791. A great and meaningful reformer, the last monarch essentially undid his own position.

In An Appeal from the Old Whigs to the New, the grand Anglo-Irish statesman, Edmund Burke, praised the May 3, 1791 constitution as one of the great reforms of the modern world. It should be remembered that this was the so-called “Age of Revolutions,” and Burke had witnessed both the glories of the American Revolution and the hideousness of the French Revolution. Poland’s reforms and constitution, he thought, offered real meaning, much closer to the American experience than the French one.
