Anglo-Dutch Slave Trade Treaty

The Anglo-Dutch Slave Trade Treaty (Dutch: Brits-Nederlands verdrag ter wering van de slavenhandel) was a treaty signed between the United Kingdom and the Kingdom of the Netherlands signed on 4 May 1818, aimed at preventing slave trade carried out through Dutch vessels. The treaty allowed both parties to search vessels of the other for on-board slaves. Among other things, the treaty established two Mixed Commission Courts, one with a seat in Freetown, Sierra Leone and another in Paramaribo, Suriname, which had the power to sentence slavers.

The treaty was amended and provided with additional articles by treaties concluded on 31 December 1822, 25 January 1823, 7 February 1837 and 31 August 1848.
