Lisbon's dream of establishing a trading monopoly…

Lisbon's dream of establishing a trading monopoly in its colonies has clearly not been achieved by the end of the eighteenth century.

Competition from foreign powers contributes significantly to Portugal's inability to control the slave trade, either in Angola's interior or on the coast.

In 1784, for example, the French expel a garrison that the Portuguese had established a year earlier in Cabinda.

Portugal is also concerned about the northward expansion of Dutch settlers from the Cape of Good Hope area.

Moreover, at this time the British, Dutch, and Brazilians, not the Portuguese, are contributing most of the capital and vessels used in the slave trade.

Furthermore, many of the European goods arriving at Angolan ports are coming from nations other than Portugal.
