"The Inland Customs Line which incorporated the Great Hedge of India (or Indian Salt Hedge[1]) was a customs barrier built by the British across India primarily to collect the salt tax. The customs line was begun while India was under the control of the East India Company but continued into the period of direct British rule. The line had its beginnings in a series of customs houses that were established in Bengal in 1803 to prevent the smuggling of salt to avoid the tax. These customs houses were eventually formed into a continuous barrier that was brought under the control of the Inland Customs Department in 1843." [Inland Customs Line. Wikipedia]

"South Asia or Southern Asia is the southern region of the Asian continent, which comprises the sub-Himalayan countries and, for some authorities, adjoining countries to the west and east. Topographically, it is dominated by the Indian Plate, which rises above sea level as northern parts of India south of the Himalayas and the Hindu Kush. South Asia is bounded on the south by the Indian Ocean and on land (clockwise, from west) by West Asia, Central Asia, East Asia, and Southeast Asia.
The current territories of Bangladesh, India, Sri Lanka and Pakistan form the core countries of South Asia, while Nepal, Bhutan and Maldives are generally included, and Afghanistan and Myanmar often added. By various deviating definitions based on often substantially different reasons, the British Indian Ocean Territory, Mauritius, Iran and the Tibet Autonomous Region are included as well. With the 7 core countries considered, South Asia is home to well over one fifth of the world's population, making it both the most populous and the most densely populated geographical region in the world. The South Asian Association for Regional Cooperation is an economic cooperation organisation in the region which was established in 1985." [South Asia. Wikipedia]
