The Jagiellonian dynasty became one of the leading royal houses in Europe. The great triumph of his reign was bringing Prussia under Polish rule.^[2] The rule of Casimir corresponded to the age of "new monarchies" in western Europe. By the 15th century, Poland had narrowed the distance separating it from Western Europe and became a significant power in international relations. The demand for raw materials and semi-finished goods stimulated trade, producing a positive balance, and contributed to the growth of crafts and mining in the entire country.^[3] He was a recipient of the English Order of the Garter (KG), the highest order of chivalry and the most prestigious honour in England.

Following Casimir's death in 1492, John I Albert succeeded him as King of Poland, and Alexander Jagiellon was proclaimed Grand Duke of Lithuania.^[4]
