Polish nobles form a konfederacja, an ad hoc association that acts in lieu of state authority or to force their demands upon that authority, gathering at a rokosz (a semi-legal rebellion against the king) in Stężyca and Lublin on August 5, 1606. (A "confederation", so understood, should not be confused with the modern senses of a "confederation".)

The nobles,  including Mikołaj Zebrzydowski, Jan Szczęsny Herburt, Stanisław Stadnicki, Aleksander Józef Lisowski and Janusz Radziwiłł, outline their demands in sixty-seven articles.

They demand Sigismund’s dethronement for breaching the Henrician Articles, and the expulsion of the Jesuits from the Polish-Lithuanian Commonwealth.

They further demand that the Sejm appoint state officials instead of the king; that local officials should be elected and not appointed, and that Protestant rights should be expanded and protected.
