Kalibangan: Unearthing an Early Harappan Ploughed Field

The question asks about the specific historical period associated with the discovery of a ploughed field at the archaeological site of Kalibangan, located in Rajasthan.

Kalibangan Site Significance

Kalibangan is a crucial site belonging to the Indus Valley Civilization. It provides valuable insights into the culture, agriculture, and urban planning of this ancient civilization. Excavations at Kalibangan have revealed significant findings, including evidence of town planning, pottery, seals, and notably, agricultural practices.

The Ploughed Field Evidence

One of the most remarkable discoveries at Kalibangan is the evidence of a ploughed field. This finding is particularly important as it indicates early agricultural activities in the region. The field shows furrows that were made using agricultural tools, suggesting systematic farming practices.

Dating the Kalibangan Ploughed Field

Archaeological dating and the associated pottery styles found at the same stratigraphic level place this evidence of the ploughed field firmly within the Early Harappan period. This phase represents the formative stage of the Harappan Civilization, preceding its more developed phase.

Understanding Harappan Periods

• Early Harappan Period: This is the foundational phase, characterized by the development of village communities and early urban settlements. The ploughed field at Kalibangan dates back to this era (roughly before 2600 BCE).
• Mature Harappan Period: This is the peak of the Indus Valley Civilization, known for its well-planned cities like Harappa and Mohenjo-daro, sophisticated drainage systems, and standardized weights and measures (roughly 2600 BCE to 1900 BCE). While Kalibangan was also occupied during this time, the earliest ploughed field evidence is from the preceding phase.
• Late Harappan Period: This phase marks the decline and eventual breakdown of the Indus Valley Civilization, with changes in settlement patterns and material culture (roughly after 1900 BCE).

The Chalcolithic Context

The Chalcolithic period, also known as the Copper Age, refers to a time when both stone and metal (copper) tools were used. Many Indus Valley sites, including Kalibangan, have Chalcolithic roots. While the Early Harappan culture itself falls within the broader Chalcolithic era, the specific evidence of the ploughed field at Kalibangan is most directly associated with the Early Harappan phase of the Indus Civilization, distinguishing it from later periods.

Conclusion

Therefore, the evidence of a ploughed field at Kalibangan in Rajasthan is primarily attributed to the Early Harappan period.
