The Indus (Harappan) civilization’s main urban phase—often treated as the baseline for its long-distance exchange—began around this time, creating the production scale and standardized crafts (e.g., beads, seals, weights) that underpinned external trade.
High-status tombs at Ur contain imported materials—including etched carnelian beads—commonly used as evidence for early, elite-focused exchange linking Mesopotamia to Indus-region production and distribution networks.
Later-copied tradition attributed to Sargon of Akkad describes ships from Meluhha, Magan, and Dilmun tying up at Akkad’s quay—an often-cited textual marker for Gulf maritime trade reaching as far as Meluhha (widely associated with the Indus sphere).
Inscriptions associated with Rimush’s eastern campaigns refer to fighting a coalition that included troops of Meluhha, indicating that “Meluhha” functioned in Mesopotamian records as a meaningful foreign ethnogeographic label during the late 3rd millennium BCE.
Over the course of the third millennium BCE, Gulf seaborne exchange expanded eastward to the Indus region, with scholarship commonly noting heightened activity and strong material signals across Mesopotamia, the Gulf, and Indus coastal sites.
A cylinder seal naming Shu-ilishu as an “interpreter of the Meluhhan language” is key evidence for the presence of Meluhha-associated people and/or commercial dealings requiring translation within Mesopotamian administrative settings.
Texts of Gudea (Lagash) mention obtaining bright carnelian and blocks of lapis lazuli from Meluhha, illustrating how Mesopotamian rulers framed exotic raw materials and luxury goods within named long-distance supply zones.
Shortugai in northern Afghanistan is widely described as an Indus (Harappan) trading outpost established around this time, positioned to access and route materials (notably lapis lazuli) into wider exchange systems that ultimately reached Mesopotamia.
During the Ur III period, Mesopotamian state-linked commerce through Gulf ports is described as connecting with Dilmun/Makkan/Meluhha routes; archaeological finds such as seals and carnelian beads are cited as material correlates of these links.
As the Indus civilization moved out of its main urban phase (often dated ending around 1900 BCE), Mesopotamian and archaeological indicators for intensive Indus–Mesopotamia exchange diminish, suggesting contraction or reconfiguration of long-distance networks.
Synthesis accounts of Ur III-era external relations commonly note that trade with Meluhha/Indus peaked earlier and is treated as ending after ~1900 BCE, aligning with the broader collapse/transition of Harappan urban systems.
Later Mesopotamian textual tradition preserves few (and eventually no) references to Meluhha; compilations often note that attestations cease by the early 2nd millennium BCE, consistent with reduced direct contact after Harappan urban decline.
