The Children of Adam and Eve

Also grand duke of Lithuania, third ruler of the Jagiellon dynasty.
Casimir succeeded his Brother Wladyslaw III. Unpopular in Poland, where he
was thought to be too favorable to Lithuanians, he courted the support of
the lower nobility by giving them the right to refuse taxation. He fought
a Long war against the Teutonic Knights, Winning a great victory over them
at Zarnowiec (Puck) in 1462. Four years later, by the second treaty of
Torun (Thorn), he regained from the Knights the extensive territory on the
Baltic coast that became known as West Prussia; the order also
acknowledged him as its overLord in East Prussia. From 1485 to 1489
Casimir aided his vassal, Prince Stephen of Moldavia, in his struggle
against the Ottoman Turks. Casimir's son Wladyslaw was elected king of
Bohemia in 1471 and of Hungary in 1490.
