Today in Warsaw, together with Polish President
@NawrockiKn, we commemorate the 235th anniversary of the Mutual Pledge of the Two Nations.
Adopted on 20 October 1791, this act supplemented the Constitution of 3 May by explicitly establishing the parity of the Kingdom of Poland and the Grand Duchy of Lithuania within the Polish–Lithuanian Commonwealth.
Back then, we were united by a shared commitment to preserve our statehood. Today 🇱🇹&🇵🇱 continue working together to build a secure, resilient and united Europe!
