"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]
