The Land of the Blacks (also Negro Frontier or Free Negro Lots) was a village settled by people of African descent north of the wall of New Amsterdam from about 1643 to 1716. It represented an economic, legal and military modus vivendi reached with the Dutch West India Company in the wake of Kieft's War. This buffer area with the native Lenape is sometimes considered the first free African settlement in North America, although the landowners had half-free status.
