Batavians Batavians (Latin Batavi) were a Germanic tribe, originally part of the Chatti, reported by Tacitus to have lived around the Rhine delta, in the area that is currently the Netherlands, "an uninhabited district on the extremity of the coast of Gaul, and also of a neighbouring island, surrounded by the ocean in front, and by the river Rhine in the rear and on either side" (Tacitus, Historiae iv).
