Octroi

Octroi, a French word derived from the Latin nuetoritas ("authority"), originally denoted any grant or privilege authorised by Government. It afterwards came to be used only of the taxes in kind levied in France and other countries on goods carried within the gates of towns. The injurious effect of a tax of this nature on the internal trade of a country is obvious. The French octrois were abolished during the Revolution, but again introduced in 1798.
