The construction of the canal during Darius's reign is evidenced by ancient records, including inscriptions. Darius commemorated the completion of the canal by creating stelae (stone monuments) with inscriptions in several languages, describing the construction and its benefits. The canal not only facilitated trade but also solidified Darius's control over Egypt and enhanced the Achaemenid Empire's economic and political power in the region.
