Targowica Confederation
Branicki, Potocki and Rzewuski prepared in April 1792 in St. Petersburg an act of confederation, annulling the May Constitution and bringing back the Cardinal Laws of 1768. Catherine ordered their confederation constituted at Targowica in Ukraine. The Targowica Confederation then asked the Empire for military help, and on May 18 nearly 100,000 strong Russian armies entered the Commonwealth.
