History of Poland - Jagiellon Dynasty

Jagiellon Dynasty

Beginning with the Lithuanian Grand Duke Jogaila (Władysław II Jagiełło), the Jagiellon dynasty (1386–1572) formed the Polish–Lithuanian union. The partnership brought vast Lithuania-controlled Rus' areas into Poland's sphere of influence and proved beneficial for the Poles and Lithuanians, who coexisted and cooperated in one of the largest political entities in Europe for the next four centuries. In the Baltic Sea region, Poland's struggle with the Teutonic Knights continued and included the Battle of Grunwald (German: Battle of Tannenberg; Lithuanian: Battle of Žalgiris) (1410) and in 1466 the milestone Peace of Thorn under King Casimir IV Jagiellon; the treaty created the future Duchy of Prussia. In the south, Poland confronted the Ottoman Empire and the Crimean Tatars, and in the east helped Lithuania fight the Grand Duchy of Moscow. Poland was developing as a feudal state, with predominantly agricultural economy and an increasingly dominant landed nobility component. The Nihil novi act adopted by the Polish Sejm (parliament) in 1505, transferred most of the legislative power from the monarch to the Sejm. This event marked the beginning of the period known as "Golden Liberty", when the state was ruled by the "free and equal" Polish nobility. Protestant Reformation movements made deep inroads into the Polish Christianity, which resulted in unique at that time in Europe policies of religious tolerance. The European Renaissance currents evoked in late Jagiellon Poland (kings Sigismund I the Old and Sigismund II Augustus) an immense cultural flowering. Poland's and Lithuania's territorial expansion included the far north region of Livonia.
