The Indus Valley Tradition is divided into four eras, and each era can be divided into various phases. A phase is an archaeological unit possessing traits sufficiently characteristic to distinguish it from all other units similarly conceived. [1] Each phase can be subdivided into interaction systems.
Date range
Phase
Era
7000 - 5500 BC
Mehrgarh I (aceramic Neolithic)
Early Food Producing Era
5500-3300
Mehrgarh II-VI (ceramic Neolithic)
Regionalisation Era
5500-2600
3300-2600
Early Harappan (Early Bronze Age)
3300-2800
Harappan 1 (Ravi Phase)
2800-2600
Harappan 2 (Kot Diji Phase, Nausharo I, Mehrgarh VII)
The Early Food Producing Era corresponds to ca. 7000-5500 BCE. It is also called the Neolithic period. The economy of this era is based on food production, and agriculture developed in the Indus Valley. Mehrgarh Period I belongs to this era.
Regionalization Era
The Regionalization Era corresponds to 5500-2600 BCE. The Early Harappan phase belongs to this Era. This era was very productive in arts, and new crafts were invented. The Regionalization Era includes the Balakot, Amri, Hakra and Kot Diji Phases.
1A/B
Ravi aspect of the Hakra Phase
ca. 3300-2800 BCE
2
Early Harappan/Kot Diji Phase
ca. 2800-2600 BCE
Integration Era
The Integration Era refers to the period of the "Indus Valley Civilization". It is a period of integration of various smaller cultures.
3A
Harappan Phase
ca. 2600-2450 BCE
3B
Harappan Phase
ca. 2450-2200 BCE
3C
Harappan Phase
ca. 2200-1900 BCE
Localization Era
The Localization Era (1900-1300 BCE) is the fourth and final period of the Indus Valley Tradition. It refers to the fragmentation of the culture of the Integration Era.
The Localization Era comprises several phases (Shaffer 1992):
Punjab Phase (Cemetery H, Late Harappan). The Punjab Phase includes the Cemetery H and other cultures. Punjab Phase sites are found in Harappa and in other places.
S. P. Gupta periodized the Harappan Civilization in a chronological framework that spans the dates from 4000 BCE to 1400 BCE, taking into account new discoveries:[2]
Formative Phase
e.g.,Mehrgarh-IV-V
ca. 4000-3500 BCE
Early Phase
e.g., Kalibangan-I
ca. 3500 - 2800 BCE
Period of Transition
e.g., Dholavira-III
ca. 2800 - 2600 BCE
Mature Phase
e.g., Harappa-III, Kalibangan-II
ca. 3500 - 2800 BCE
Late Phase
e.g., Cemetery H, Jhukar
ca. 1900 - 1500 BCE
Final Phase
e.g., Dholavira
ca. 1500 - 1400 BCE
Another older nomenclature classifies the Indus Valley Civilization into Early, Mature and Late Harappan. According to Erdosy, the Indus Valley Tradition nomenclature "is much more informative than the traditional Early/Mature/Late Harappan classification which should now be discarded." [3]
