The 'Chattuarii' ot ''Attoarii'' are a tribe of the
Franks. They lived originally east of the northern
Rhine and west of the
Chatti, that later were called
Thuringii. Their land was south of the
Bructeri. In the 5th century many Chattuari crossed the Rhine and settled in the area between the northern
Maas and Rhine, right west of their origin. From the 7th century on they must have formed a part of the
Ripuarians.
The Chattuarii also appear in the poem
Beowulf as "Hetwaras" where they form a lieger together with the Hugas (
Chauci) and the
Frisians to fight against a Geatish raiding force. The
Geats are defeated and their king
Hygelac is killed, Beowulf alone escaping. According to
Widsith, the ''Hætwera'' were ruled by Hun.
