Periodisation of the Indus Valley Civilisation

--------------

The most commonly used nomenclature classifies the Indus Valley civilisation into early, mature, and late Harappan phases. The Indus Valley Civilisation was preceded by local agricultural villages, from where the river plains were populated when water management became available, creating an integrated civilisation. This broader time range has also been called the Indus Age and the Indus Tradition.

### Early, Mature, and Late Harappan

Early surveys by [Sir Aurel Stein](/wiki/Sir_Aurel_Stein "Sir Aurel Stein") in [Balochistan](/wiki/Balochistan "Balochistan") led to the discovery of numerous prehistoric sites of unknown association. Following excavations at Harappa and Mohenjo Daro, the prehistoric sites in Sindh and Baluchistan were thought to represent a culture that migrated from Baluchistan to the Indus Valley to establish the Indus Valley Civilisation. This notion was refuted by [M.R. Mughal](/wiki/Mohammed_Rafique_Mughal "Mohammed Rafique Mughal") based on his discovery of earlier occupational phases in the Cholistan Desert. The term [Early Harappan](/wiki/Early_Harappan "Early Harappan") was coined by M. R. Mughal in his dissertation at the University of Pennsylvania which provided a synthesis of his many surveys and studies throughout Pakistan. This classification is primarily based on Harappa and Mohenjo Daro, assuming an evolutionary sequence. According to Manuel, this division "places the Indus Valley within a tripartite evolutionary framework, of the birth, fluorescence, and death of a society in a fashion familiar to the social evolutionary concepts of [Elman Service](/wiki/Elman_Service "Elman Service") (1971\)."

According to [Coningham](/wiki/Robin_Coningham "Robin Coningham") and Young, it was "cemented \[...] in common use" due to "the highly influential British archaeologists Raymond and Bridget Allchin \[who] used similar subdivisions in their work." According to Coningham and Young, this approach is "limited" and "restricted," putting too much emphasis on the mature phase.

### Shaffer: Harappan Tradition

Scholarship in archaeology commonly uses a variation of the [Three\-age system](/wiki/Three-age_system "Three-age system") developed by [Christian Jürgensen Thomsen](/wiki/Christian_J%C3%BCrgensen_Thomsen "Christian Jürgensen Thomsen") to divide past societies into a Stone Age, a Bronze Age, and an Iron Age. Although this system is very useful for its original purpose of organizing museum collections, it is unable to fully characterize the dynamic and fluid nature of human inter\-settlement relationships. To address this issue, archaeologists [Gordon Willey](/wiki/Gordon_Willey "Gordon Willey") and [Philip Phillips](/wiki/Philip_Phillips_%28archaeologist%29 "Philip Phillips (archaeologist)") developed a system based on *Culture\-Historical Integration*, or a heuristic concept for describing the distribution of "relatedness" across time and space. These concepts were later adapted by Jim G. Shaffer and Diane Liechtenstein as a potential solution to a similar problem in the Greater Indus Valley.

During his archaeological research in Afghanistan, Baluchistan, Pakistan, and India, Shaffer observed the fluid and adaptive nature of local customs in rural South Asia and the many ways that cultural practices interfaced with material culture. Based on both his extensive work in the field and these ethnographic observations, Shaffer developed a series of important critiques of archaeological theory. Shaffer and Liechtenstein argued that the colonial legacy of Mortimer Wheeler and Stuart Piggot led to the projection of colonial stereotypes onto the ancient past. As a result of these critiques, Shaffer adapted the system developed by Willey and Phillips into one suitable for the Indus Valley Civilisation. In his original publication, this complex social formation was termed the *Harappan Tradition*, after the type site at Harappa, Punjab. This term *Tradition* stems from his concept of *Cultural Tradition* or the "persistent configuration of basic technologies, as well as structure, in the context of geographical and temporal continuity".

Shaffer divided the broader Indus Valley Tradition into four eras, the pre\-Harappan "Early Food Producing Era," and the Regionalisation, Integration, and Localisation eras, which correspond roughly with the Early Harappan, Mature Harappan, and Late Harappan phases. 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. According to Shaffer, there was considerable regional variation, as well as differences in cultural sequences, and these eras and phases are not evolutionary sequences, and cannot uniformly be applied to every site.

According to Coningham and Young,

Coningham \& Young raise theoretical concerns with Shaffer's periodisation, noting that

#### Eras

The Early Food Producing Era corresponds to ca. 7000\-5500 BCE. It is also called the Neolithic period. The economy of this era was based on food production, and agriculture developed in the Indus Valley. [Mehrgarh](/wiki/Mehrgarh "Mehrgarh") Period I belongs to this era. 
The Regionalisation Era corresponds to ca. 4000\-2500/2300 BCE (Shaffer) or ca. 5000\-2600 BCE (Coningham \& Young). The Early Harappan phase belongs to this Era. According to Manuel, "the most significant development of this period was the shift in population from the uplands of Baluchistan to the floodplains of the Indus Valley." This era was very productive in arts, and new crafts were invented. The Regionalisation Era includes the [Balakot](/wiki/Balakot "Balakot"), [Amri](/wiki/Amri_culture "Amri culture"), [Hakra](/wiki/Hakra "Hakra"), and [Kot Diji](/wiki/Kot_Diji "Kot Diji") Phases.

The Integration Era refers to the period of the "[Indus Valley civilisation](/wiki/Indus_Valley_civilisation "Indus Valley civilisation")". It is a period of integration of various smaller cultures.
The Localisation 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 Localisation Era comprises several phases:
* [Punjab Phase](/wiki/Punjab_Phase "Punjab Phase") ([Cemetery H](/wiki/Cemetery_H "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.
* [Jhukar Phase](/wiki/Jhukar_Phase "Jhukar Phase") ([Jhukar](/wiki/Jhukar "Jhukar") and [Pirak](/wiki/Pirak "Pirak")) The Jhukar Phase refers to Mohenjo\-daro and sites in Sindh.
* [Rangpur Phase](/wiki/Rangpur_Phase "Rangpur Phase") (Late Harappan and Lustrous Red Ware). The Rangpur Phase sites are in [Kachchh](/wiki/Kachchh "Kachchh"), Saurashtra, and mainland Gujarat.
* The Pirak Phase is a phase of the Localisation Era of both the Indus Valley Tradition and the Baluchistan Tradition.

### Possehl: Indus Age

[Gregory Possehl](/wiki/Gregory_Possehl "Gregory Possehl") includes the Neolithic stage in his periodisation, using the term *Indus Age* for this broader timespan, Possehl arranged archaeological phases into a seven\-stage sequence: 
1. Beginnings of Village Farming Communities and Pastoral camps
2. Developed Village Farming Communities and Pastoral camps
3. Early Harappan
4. Transition from Early Harappan to Mature Harappan
5. Mature Harappan
6. Posturban Harappan
7. Early Iron Age of Northern India and Pakistan

According to Coningham \& Young,

### Rita Wright

A "similar framework" as Shaffer's has been used by [Rita Wright](/wiki/Rita_P._Wright "Rita P. Wright"), looking at the Indus "through a prism influenced by the archaeology of Mesopotamia," using the terms Early Food Producing Phase, Pre\-Urban Phase, Urban Phase, and Post\-Urban Phase.
