Przemysł II (also given in English and Latin as Premyslas or Premislaus or less properly Przemysław; 14 October 1257 – 8 February 1296), was the Duke of Poznań from 1257–1279, of Greater Poland from 1279–1296, of Kraków from 1290–1291, and Gdańsk Pomerania (Pomerelia) from 1294–1296, and then King of Poland from 1295 until his death. After a long period of Polish High Dukes and two nominal kings, he was the first to obtain the hereditary title of King, and thus to return Poland to the rank of Kingdom.
