Eventually, the Union of Lublin of 1569 created a new state, the Polish–Lithuanian Commonwealth. In the Federation, the Grand Duchy of Lithuania maintained its political distinctiveness and had separate ministries, laws, army, and treasury. The federation was terminated by the passing of the Constitution of 3 May 1791, when it was supposed to become a single country, the Commonwealth of Poland, under one monarch, one parliament and no Lithuanian autonomy. Shortly afterward, the unitary character of the state was confirmed by adopting the Reciprocal Guarantee of Two Nations.
