Biography
Casimir IV Jagiellon secured the union of Poland and Lithuania not by conquest, but through thirteen years of relentless diplomatic and military pressure against the Teutonic Order. His victory in the Thirteen Years’ War, concluded by the Second Peace of Thorn in 1466, reclaimed Pomerelia and the crucial port of Gdańsk for the Polish Crown. This monarch is often overshadowed by his more warlike successors, yet his reign provided the territorial and economic foundation for the Polish-Lithuanian Commonwealth. He ruled for 45 years, a period of internal stability and external expansion that transformed a personal dynastic union into a lasting geopolitical entity. His legacy is a map of Central Europe redrawn.
