- Darius murdered Gaumata and in his own person restored the royal line.
- Though Darius was an excellent soldier and extended his empire east, north, and into Europe, he saw himself as an organizer and lawgiver rather than as a mere conqueror.
- Darius established a system of well-maintained all-weather roads and a royal courier system with post-houses and regular relays of horses and riders in Persia.
- Darius, himself a firm supporter of Ahura Mazda, the Zoroastrian god, said in the Behistun inscription that Ahura Mazda "gave" him his kingdoms, and with him Zoroastrianism became something like the national religion of the Persians. For the empire, however, he continued Cyrus's policy of toleration of local cults, and this mildness became and remained, except perhaps under Xerxes, a distinctive feature of Persian rule.\
- Darius I "the Great" (549-486 BCE) was a king of Persia who ruled for 35 years, from September 522 BCE to October 486 BCE. He was the third Achaemenian king and was considered by many to be "the greatest of the Achaemenian kings." During his reign, Darius completed the work of his predecessors, and not only did he "hold together the empire," but he also extended it in all directions. Thus, with Darius as Great King, Achaemenian Persia became the largest empire in the world.
