W adys aw the Short or Elbow-high (or Ladislaus I of Poland, Polish: W adys aw I okietek; 1261 2 March 1333), was a King of Poland. He was a Duke until 1300, and Prince of Kraków from 1305 until his coronation as King on 20 January 1320. Later histories refer to him also as W adys aw IV or W adys aw I. There are no records to show that he actually used any regnal number. Both numerals are retrospective assignments by later historians. IV comes from him being the fourth of that name to rule as overlord of the Polish, since W adys aw I Herman. It comes from him having restored the monarchy after a fragmented era of a century or more, and also backwards-counting from W adys aw of Varna who officially used III and W adys aw Vasa who officially used IV.
