With the Chatti, the Mattaci took part in the Revolt of the Batavi in 69 AD, besieging the Roman city of "Mogontiacum" (present-day Mainz). After the foundation of the Limes Germanicus, the tribal identity of the Mattiaci seems to have eroded away. When the municipality of the Civitas Mattiacorum had been established unter emperor Trajan, the citizens of "Aquae Mattiacorum" referred to themselves as "vicani Aquaenses" instead of "Mattiaci".
