BMAC to post-BMAC reorganization in Bactria and Margiana
Major fortified centers, villages, mobile sites and exchange systems changed unevenly around the end of mature BMAC phases.

What is the evidence?
observation
Major fortified centers, villages, mobile sites and exchange systems changed unevenly around the end of mature BMAC phases.Review and provenance
Specialist reviewer: not recorded. Review date: not recorded.
Dataset workflow: proposed. This is separate from specialist review.
Confidence describes the stated assessment; it does not certify expert approval. How review works.
Chronology
Dating intervals may describe uncertainty or phases; their width alone does not establish event duration.
1900 BCE–1500 BCE
Precision: range
moderateContextual record outside all or part of the primary interval.

Interpretation and caveats
The evidence supports regional contraction, relocation, technological continuity and new community configurations rather than a single collapse or replacement event.
Event context
Classification
Event type: oasis system reorganization
Evidence layer: archaeological
Timeline role: regional core
People and places
Locations: Bactria-Margiana Archaeological Complex / Oxus Civilization, Post-BMAC Murghab communities, Murghab Delta and Margiana oasis system, Iranian plateau, Afghanistan and Indus connection frame
Why it matters to the timeline
The transition directly structures the southern Central Asian interval and its links to Afghanistan and Iran.
