⚔️ A pagan Lithuanian prince took the crown of the most Catholic kingdom in the region. That deal, signed at Krewo castle in 1385, began the Jagiellonian dynasty, and under it Poland and Lithuania grew into one of the largest states in Europe. Both sides came to the table with their own calculations. The Polish nobility, the so-called szlachta, wanted a king who was not a German and an ally against the Teutonic Order. Jogaila needed backing of his own. He had taken power in Lithuania by imprisoning his uncle, and his cousin Vytautas was already fighting him with crusader support. To Jadwiga, crowned in Krakow at eleven and crowned specifically as king rather than queen, the whole arrangement was presented as a spiritual mission, since the condition of the wedding was the baptism of Lithuania.
👑 What followed were sixty years that turned a marriage into a great power. Christianizing the last major pagan state in Europe did not end the war with the Teutonic Knights, because the Order wanted land, not souls. Grunwald settled nothing for good either. Marienburg held out, and three more wars were needed before the Order stopped dictating terms. Along the way Jogaila secured Galicia and Podolia, crushed the revolt of Władysław Opolczyk, and finally split power in Lithuania with Vytautas. Then it almost fell apart. His son Władysław picked up the Hungarian crown as well, marched against the Ottomans, and died at Varna at twenty. Barely a quarter of that army made it home. The dynasty kept the Polish throne through backroom deals in the sejm, and its real peak was still ahead, under Casimir IV and his sons.
