Lumajang is one of the ancient cities in Java which still exist up to this day. According to Mula Malurung artifact (dated 1177 Saka), Lumajang was then ruled by King Nararyya Kirana Sminingrat. The date of the artifact, which is 15 December 1255 in the Gregorian calendar, was decided as the date of establishment of Lumajang.
