Strangford Treaty
The Strangford Treaty was an 1810 treaty between the Portuguese colony of Brazil and the United Kingdom. It provided major concessions to the British in the form of tariff reductions and other benefits.
In 1785, a decree proclaimed that Brazilian factories could only produce cloth that would be used for clothing slaves or to make sacks for food goods. This decree was lifted in 1808, accompanied by an open ports policy. To help recover their internal industry, Brazil imposed Tariff protection on imports.
