There were different Persian rulers named Darius, but this was the first one, called Darius Hystapes (522-486 B.C.). He came to power two years before these visions, and immediately after defeating Babylon allowed exiles to return.
Palikuwa na watawala wengi wa Kiajemi walioitwa Dario, lakini huyu alikuwa ndiye wa kwanza, aliitwa Dario Hystapes (mwaka 522-486 KK). Alianza kutawala miaka miwili kabla ya maono haya, na mara baada ya kuishinda Babeli aliwaruhusu Wayahudi waliokuwa uhamishoni warejee makwao.
