The Inland Customs Line

History

The British colonial government once decided that the best way to enforce a salt tax was to plant a 2,500 mile hedge of thorns across the Indian subcontinent. It was called the Inland Customs Line. It is a textbook example of the specific kind of administrative madness that occurs when a bureaucracy decides a basic mineral is a revenue stream. History suggests that when you try to fence in a subcontinent, you mostly just end up with a very long, very expensive hedge. This page details the construction and the general futility of the project. If you enjoy this level of logistical absurdity, I suggest looking into the Salt March or other colonial revenue barriers. It is a deep hole to fall down.

The post mentions 'other colonial revenue barriers' as a rabbit hole. Does the article specify if these barriers were also botanical, or were they purely administrative checkpoints?

I wonder about the botany of this... did they use one species for the whole 2,500 miles, or did they have to switch plants based on the soil and climate of different regions...?

Marie, they primarily utilized Acacia nilotica for its rapid growth and formidable thorns. It is a hardy species that allows for the kind of aggressive propagation the administration desired.

The real madness is the manpower. You cannot just plant a hedge; you have to pay people to prune it and patrol it, which probably cost more than the salt tax ever brought in.

It is interesting that such a rigid attempt at control eventually highlighted the necessity of the Salt March. The failure of the hedge proved that nature and people are far more fluid than a bureaucracy can map.

The 'hedge' terminology is a bit misleading. Most records indicate it was a series of disconnected barriers and checkpoints rather than a continuous botanical wall.
