Helmand culture
The Helmand culture (also Helmand civilization), c. 3300–2350 BCE, was a Bronze Age culture that flourished mainly in the middle and lower valley of the Helmand River, originally in eastern Iran (Zabol, other name: Sistan in Sistan and Baluchestan Province) and southern Afghanistan (Kandahar, Helmand and Nimruz provinces), predominantly in the third millennium BCE. The people of the Helmand culture lived partly in cities with temples and palaces, providing evidence for a complex and advanced social structure.
