Manda and Alamgirpur as boundary sites

Manda is located at approximately 32° 47′ N latitude and 74° 48′ E longitude in the Jammu district of the Union Territory of Jammu and Kashmir, India. It is situated on the right bank of the Chenab River (historically known as the Asikni), nestled in the foothills of the Pir Panjal range of the Himalayas. This strategic position represents the absolute northernmost geographical boundary marker of the Mature Harappan Civilization.

History of Discovery and Excavation

The archaeological potential of the site was first identified during surface re-connaissance in the 1970s. The Archaeological Survey of India (ASI) conducted systematic excavations at Manda during the field season of 1976–77 under the leadership of veteran archaeologists Jagat Pati Joshi and Madhu Bala.

Stratigraphy and Cultural Sequence

Excavations at Manda revealed a 92 cm thick cultural deposit divided into three distinct structural and temporal periods, showing an uninterrupted transition into historical times:

• Period IA (Mature Harappan): Characterized by the coexistence of standard Mature Harappan pottery and Pre-Harappan/Early Harappan Bara ware. Artifacts include characteristic red ware, perforated jars, and incised pottery.
• Period IB (Late Harappan): Marked by the decline of classical Harappan traits, a complete dominance of Bara-style ceramic traditions, and the disappearance of urban civic planning elements.
• Period II (Early Historical Period): Characterized by the presence of Northern Black Polished Ware (NBPW) and associated historical cultural debris, indicating a long chronological gap after the Harappan abandonment.

Material Culture and Economic Significance

Despite its small size relative to metropolitan capitals, Manda yielded crucial artifacts indicating tight integration with the Harappan administrative and economic network:

• Copper Artifacts: A significant discovery of a copper double-spiral headed pin, which shows distinct typological affinities with similar pins found in Central Asia and West Asia, suggesting long-distance trade connections.
• Tools and Weapons: A considerable corpus of bone arrowheads with socketed tangs, chert blades, and terracotta cakes.
• Administrative Markers: An unfinished steatite seal and fragments of clay sets bearing impressions of the undeciphered Indus Script, verifying its role as an official administrative outpost.
• Economic Function: Manda functioned primarily as a strategic timber-procurement and mineral-sourcing station. It controlled the riverine transit of deodar, cedar, and pine wood floated down the Chenab River from the Himalayan highlands to the lowland cities of Punjab and Sindh.

Alamgirpur: The Eastern Frontier

Geographic Location and Hydro-Geological Context

Alamgirpur is located at approximately 29° 00′ N latitude and 77° 29′ E longitude in the Meerut district of Uttar Pradesh, India. The site lies on the left bank of the Hindon River, a major tributary of the Yamuna River. It marks the absolute easternmost geographical boundary of the Indus Valley Civilization, representing the expansion of the culture into the fertile Upper Ganga-Yamuna Doab.

History of Discovery and Excavation

• 1958: The site was discovered during a regional survey by the Punjab University, Chandigarh.
• 1959: Dr. Yagya Dutt Sharma (Y.D. Sharma) of the Archaeological Survey of India (ASI) conducted the first systematic excavation, establishing its Harappan credentials.
• 2008: The ASI and the State Archaeology Department initiated re-excavations to re-verify the site’s stratigraphy and gather organic samples for modern absolute dating techniques.

Stratigraphy and Cultural Sequence

The vertical excavation profile at Alamgirpur reveals four distinct cultural periods separated by significant chronological breaks (hiatuses):

• Period I (Mature to Late Harappan): The foundational layer containing urban Harappan elements transitioning into a localized Late Harappan phase.
• Period II (Painted Grey Ware – PGW Culture): An Iron Age settlement layer separated from the Harappan layer by a distinct break in deposition, characterized by fine grey pottery with geometric paintings.
• Period III (Northern Black Polished Ware – NBPW Culture): Representing the urbanized Early Historical phase of the Mahajanapada era.
• Period IV (Late Historical/Medieval Period): Featuring structural remains and pottery matching the early medieval periods of Northern India.

Material Culture and Key Findings

• Ceramics and Inscriptions: The ceramic assemblage includes platters, cups, dishes-on-stand, and large storage jars. A highly significant discovery is a series of open texturized impressions of woven textile cloth on a wet clay trough, providing concrete evidence of Harappan textile weaving technologies. Some pottery sherds feature graffitis incised with characters of the Indus Script.
• Terracotta Art: The site yielded diverse terracotta objects, including figurines of humped bulls, snakes, beads, toy cartwheels, and highly specific terracotta cakes (both circular and triangular variants).
• Animal Husbandry and Subsistence: Zooarchaeological analysis of faunal remains revealed fractured bones of domesticated cattle, buffaloes, sheep, and goats, alongside wild game. This indicates a mixed economy based on intensive multi-crop agriculture (wheat, barley) and pastoralism optimized for the humid Doab ecology.

Comparative Synthesis for Prelims

Strategic Contrasts

Manda and Alamgirpur illustrate the high ecological adaptability of the Harappan urban planning model. Manda represents a highland, river-valley frontier specialized in resource extraction (lumber, stones) from the sub-Himalayan ecological zone. Conversely, Alamgirpur represents a lowland, humid alluvial agricultural outpost designed to tap into the fertile agricultural potential of the Ganga-Yamuna Doab. This expansion during the late phases of the civilization cushioned the urban core as the core Ghaggar-Hakra systems began desiccating.
