How did Darius I improve life in the Persian empire

Darius organized the empire by dividing it into provinces and placing satraps to govern it. He organized Achaemenid coinage as a new uniform monetary system, along with making Aramaic the official language of the empire.

Darius the Great further expanded the empire and introduced reforms such as standard currency and satraps—provincial governors—to rule over smaller regions of the empire on his behalf. The increased wealth and power of the empire allowed Darius to construct a brand new capital city, called Persepolis.
