Characteristics
Enclaves may be created for a variety of historical, political or geographical reasons. Some areas have been left as enclaves by changes in the course of a river.
Since living in an enclave can be very inconvenient and many agreements have to be found by both countries over mail addresses, power supply or passage rights, enclaves tend to be eliminated and many cases that existed before have now been removed. The governments of India and Bangladesh have been pressed to resolve the complex system of enclaves along their border - persons in these enclaves have complained of being effectively stateless. In 2011, India and Bangladesh signed a leasehold agreement regarding the Tin Bigha Corridor.
Many exclaves today have an independence movement, especially if the exclave is far away from the mainland.
