Cooch Behar Indo-Bangladesh Enclaves
"The historical enclave complex featuring the world's only 3rd-order counter-enclave"
Until the historic Land Boundary Agreement of 2015, the border contained 102 Indian enclaves in Bangladesh and 71 Bangladeshi enclaves in India, including Dahala Khagrabari—an Indian parcel inside a Bangladeshi enclave, inside an Indian enclave, inside Bangladesh.
Historical Genesis & Geopolitics
Resulted from 18th-century stakes won in chess games and card games between the Maharaja of Koch Bihar and the Mughal Faujdar of Rangpur. Resolving it in 2015 gave 50,000 stateless residents official citizenship.
Cartographic Mechanism & Impact
A topological nightmare for GIS databases, requiring nested third-order polygon indexing until the 2015 land swap simplified the border into a single continuous polygon.
