WLADISLAUS (WLADIsLAw), the name of four kings of Poland and two Polish kings of Hungary'.
'In Hungarian history the Polish Wladislaus (Mag. Ulasz16) is distinguished from the Hungarian Ladislaus (Laszlo). They are reckoned separately for purposes of numbering. Besides the Wladislaus kings of Poland, there were three earlier dukes of this name: Wladislaus I. (d. 1102), Wladislaus II. (of Cracow, d. 1163) and Wladislaus III.,
duke of Great Poland and Cracow (d. 1231). By some historians these are included in the numbering of the Polish sovereigns, King Wladislaus I. being thus IV. and so on.
