India-Bangladesh enclaves

Wikipedia has an article about this topic at: India–Bangladesh enclaves

The India-Bangladesh enclaves were a system of hundreds of enclaves between India and Bangladesh, caused by ancient agreements. People living in many of these enclaves have typically had few rights as citizens in India and Bangladesh, have had limited access to basic needs and resources, and thus have lived in extreme poverty and destitution.

The enclave system was largely resolved with a new agreement in 2015 with changes being implemented between 2015-2016.
