Party) when the Great Sejm begun in 1788. After some initial political manevrouving, the issues of a closer relation with Prussia (that would eventually grew into the Polish-Prussian alliance) and a major reform of the government, both with which he was closely involved, begun accelerating in 1789. At first supportive more of a republican form of a government, political reality (such as royal faction victory at the elections of 1790) resulted in his acceptance of a more constitutional monarchy approach. In 1790, through the mediation of Scipione Piattoli, the king and Potocki begun drifting closer together, working on a draft document that would eventually become the 3 May 1791 constitution. Alongside Poniatowski, Kołłątaj and Piattoli, he is seen as one of the major authors of that document. He supported the quasi-coup d'état in which the constitution was passed on 3 May 1791. On 17 May 1791, he resigned his position in the Commission of National Education to take an appointment (Minister of Police) in the newly created government, the Guard of Laws. From March 1792 he also held the position of Minister of War. During the War in the Defence of the Constitution in 1792, he went on an unsuccessful diplomatic mission to Berlin to request assistance from the Prussian government.

He co-authored a work with Hugo Kołłątaj, On the Adoption and Fall of the Polish Constitution of 3 May (O ustanowieniu i upadku Konstytucji Polskiej 3-go Maja, 1793). Potocki participated in preparations for the Kościuszko Uprising of 1794. In early April he left Leipzig and arrived in Kraków. He was involved in unsuccessful diplomatic negotiations with various foreign powers, in a vain attempt to gain support for the insurgents. During the Uprising he served as a member of the Supreme National
