Namazga culture was preceded in the area by the Jeitun culture.
Chronology
It is believed[by whom?] that the Anau culture of Turkmenistan considerably precedes the Namazga culture in the area. Namazga I period (c. 4000–3500 BC),[1] is considered contemporary with Anau IB2 period.[citation needed]
Namazga V (c. 2400–2000 BC),[1] is in the Integration Era or the period of "urban revolution" following the Anatolian model[clarification needed] with little or no irrigation. Namazga-Tepe emerges as the production and probable governmental center[of what?], covering some 60 hectares, with Altyndepe likely a secondary capital. Around 1600 BC, Altyndepe is abandoned, and Namazga-Tepe shrinks to a fraction of its former size.
