Csanád County
According to historian Attila Zsoldos he is not identical with his contemporary namesake, who functioned as Palatine of Hungary at the same time, from 1197 to 1198. Judge royal Esau also held the office of "ispán" of Csanád County between 1197 and 1198. Furthermore, non-authentic charters also propose that Esau was already Judge royal since 1193–1195, which data does not conflict with reliable sources.
