This database contains 85 to 90 percent of the Dutch interlopers between 1674 and 1730. In the seventeenth and eighteenth centuries the word ‘interloper’ (lorrendraaier) generally referred to a smuggler ship, a ship trading goods and slaves out of the monopoly of the West Indian Company. ‘Since interloper activity was illegal, documentation concerning its role is difficult to find, if available at all’ (Postma). About one fifth of the interlopers didn’t fulfil its journey. They were captured by the West Indian Company, were shipwrecked of hijacked by pirates. More on interlopers can be read in the summary of the book ‘Lorrendrayen op Africa’ by Paesie that is added in PDF-format in this database.
