Ladislaus I of Hungary
As King of Poland, Jogaila assumed the Slavic name Władysław, which roughly translates as "glorious ruler" and is often Latinised as either Wladislaus or Ladislaus. The choice evoked both Władysław I Łokietek, "the Elbow-high", who unified the kingdom a century before, and Saint Ladislaus I of Hungary, a king who had sided with the pope against the empire and Christianised Transylvania.
