[PAR] [TLE] Union of Krewo [SEP] In a strict sense, the Union of Krewo or Act of Krėva (also Union of Krevo, Act of Kreva) was a set of prenuptial promises made in the Kreva Castle on 14 August 1385 by Jogaila, Grand Duke of Lithuania, in exchange for marriage to the underage reigning Queen Jadwiga of Poland.  The act was very limited in scope and in the historiography the term "Union of Krewo" often refers not only to the particular document but to the events of 1385–1386 as a whole.  After the negotiations in 1385, Jogaila converted to Christianity, married Jadwiga, and was crowned King of Poland in 1386.  The union was a decisive moment in the histories of Poland and Lithuania; it marked a beginning of the four centuries of shared history between the two nations.  By 1569 the Polish–Lithuanian union grew into a new state, the Polish–Lithuanian Commonwealth, and lasted until the Third Partition in 1795. [PAR] [TLE] Lithuanian Civil War (1432–38) [SEP] The Lithuanian Civil War of 1432–1438 was a conflict over the succession to the throne of the Grand Duchy of Lithuania, after Vytautas the Great died in 1430 without leaving an heir.  The war was fought on the one side by Švitrigaila, allied with the Teutonic Knights, and on the other by Sigismund Kęstutaitis, backed by the Kingdom of Poland.  The war threatened to sever the Union of Krewo, the personal union between Poland and Lithuania.  Švitrigaila's alliance with the Grand Master of the Teutonic Order, Paul von Rusdorf, launched the Polish–Teutonic War (1431–1435) but failed to secure victory for Švitrigaila.
