The Batavi are an ancient 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 neighboring island, surrounded by the ocean in front, and by the river Rhine in the rear and on either side" (Tacitus, Historiae iv).
This led to the Latin name of insula Batavorum for the area.
The same name is applied to several military units, originally raised among the Batavi.
The tribal name, probably a derivation from batawjō ("good island", from Germanic bat- "good, excellent" and awjō "island, land near water"), refers to the region's fertility, today known as the fruitbasket of the Netherlands (the Betuwe).Finds of wooden tablets show that at least some were literate.
