This ultimately led to the formation of the 1768 Bar Confederation; a szlachta rebellion directed against Russia and the Polish king which fought to preserve Poland's independence and the szlachta's traditional privileges. Unfortunately, attempts at reform provoked the union's neighbours, and in 1772 the First Partition of the Commonwealth by Russia, Austria and Prussia took place; an act which the "Partition Sejm", under considerable duress, eventually "ratified" fait accompli. Disregarding this loss, in 1773 the king established the Commission of National Education, the first government education authority in Europe.
