Darius I, an Achaemenid king who rules from 522 to 486 BCE, consolidates Persian rule of present Afghanistan through the provinces, or satrapies, of Aria (in the region of modern Herat), Bactria (Balkh), Sattagydia (Ghazni to the Indus River), Arachosia (Qandahar), and Drangiana (Seistan).
Constant bitter and bloody revolts of tribal peoples living in Arachosia (Qandahar and Quetta) plague the Persian empire.
