The opponents of the reforms who set the Targowica Confederation in 1792 hindered the functioning the Commission of National Education existing since 1773 and the educational system in the Republic of Poland. At that time two educational commissions were founded: The Crown Commission of the Education and the Lithuanian Commission of Education, Two Principal Schools at that time, the Crown Principal School in Cracow and the Principal School of the Grand Duchy of Lithuania in Vilnius did not agree to that division of the Commission of National Education. This situation had a negative impact on not only organizational area but also mainly financial matter. The settlement of the educational case took place during the session of the Grodno Seym in 1793 - the last session of The Rzeczpospolita Seym. The delegation of both universities began the action of saving the unity of the Educational commission. Professor Jan Sniadecki (1756-1830) appeared in the name of the Crown, whereas the Principal School of the Grand Duchy of Lithuania was represented by Chancellor Marcin Poczbut (1728-1810) and Professor Hieronim Stroynowski (1752-1815). They demanded guarantee of payment for professors of The Principal Schools, safeguarding of the royal privileges for the universities, and Law regulations of the former Commission of National Education. In accordance with The Grodno Seym decision, only one educational commission was established. It was named the Educational Commission of Both Nations. The Principal Schools were supposed to work according to the laws of the former Educational Commission, at the same time both their association with lower level schools or un-restricted fund management were partly limited.
