The Chatti (also Chatthi or Catti) were an ancient Germanic tribe whose homeland was near the upper Weser. They settled in central and northern Hesse and southern Lower Saxony, along the upper reaches of the Weser River and in the valleys and mountains of the Eder, Fulda and Weser River regions, a district approximately corresponding to Hesse-Kassel, though probably somewhat more extensive. According to Tacitus, the Batavians of his time were descended from a part of the Chatti, who left their homeland after an internal quarrel drove them out, to take up new lands at the mouth of the Rhine.
While Julius Caesar was well informed about the regions and tribes on the eastern banks of the Rhine, he never mentions the Chatti. Julius Caesar does not mention the Chatti by name, but noted the Suebi and suggested that they had previously driven out the Celts to the south of the Hesse-Kassel region in the prior centuries BC. Pliny the Elder, in his Natural History grouped the Chatti and Suebi together with the Hermunduri and the Cherusci, calling this group the Hermiones, which is a nation of Germanic tribes mentioned by Tacitus as living in inland Germany.
The first ancient writer to mention the Chatti is Strabo, some time after 16 AD, who includes the Chatti in a listing of "poorer Germanic tribes" (poorer than even the nomadic tribes in central and eastern Germania) that had previously fought the Romans, and had been defeated and plundered. For the first century AD, Tacitus provides important information about the Chatti's part in the Germanic wars and certain elements of their culture. He says that:
[The Chatti's] settlements begin at the Hercynian forest, where the country is not so open and marshy as in the other cantons into which Germany stretches. They are found where there are hills, and with them grow less frequent, for the Hercynian forest keeps close till it has seen the last of its native Chatti. Hardy frames, close-knit limbs, fierce countenances, and a peculiarly vigorous courage, mark the tribe. For Germans, they have much intelligence and sagacity; they promote their picked men to power, and obey those whom they promote; they keep their ranks, note their opportunities, check their impulses, portion out the day, intrench themselves by night, regard fortune as a doubtful, valour as an unfailing, resource; and what is most unusual, and only given to systematic discipline, they rely more on the general than on the army. Their whole strength is in their infantry, which, in addition to its arms, is laden with iron tools and provisions. Other tribes you see going to battle, the Chatti to a campaign. Seldom do they engage in mere raids and casual encounters. It is indeed the peculiarity of a cavalry force quickly to win and as quickly to yield a victory. Fleetness and timidity go together; deliberateness is more akin to steady courage.
A practice, rare among the other German tribes, and simply characteristic of individual prowess, has become general among the Chatti, of letting the hair and beard grow as soon as they have attained manhood, and not till they have slain a foe laying aside that peculiar aspect which devotes and pledges them to valour. Over the spoiled and bleeding enemy they show their faces once more; then, and not till then, proclaiming that they have discharged the obligations of their birth, and proved themselves worthy of their country and of their parents. The coward and the unwarlike remain unshorn. The bravest of them also wear an iron ring (which otherwise is a mark of disgrace among the people) until they have released themselves by the slaughter of a foe. Most of the Chatti delight in these fashions. Even hoary-headed men are distinguished by them, and are thus conspicuous alike to enemies and to fellow-countrymen. To begin the battle always rests with them; they form the first line, an unusual spectacle. Nor even in peace do they assume a more civilised aspect. They have no home or land or occupation; they are supported by whomsoever they visit, as lavish of the property of others as they are regardless of their own, till at length the feebleness of age makes them unequal to so stern a valour.
Between the Rhine and the Chatti, Tacitus places the Tencteres and Usipetes, who had apparently been moved since the time of Caesar into the old homeland of the Ubii, who had in turn settled in Cologne. (Caesar had described these three tribes as under pressure from Suebi to their east, and attempting to move across the Rhine.) To the south, Tacitus also says that the Chatti's land is beyond the questionable lands, the so called tithe lands, or agri decumates, that adventurers from the Roman sides of the Rhine and Danube had been trying to settle. It is possible that at first the Chatti themselves moved into place on the Rhine, in the old territory of the Ubii. Cassius Dio describes Drusus establishing a fort in Chatti territory on the Rhine itself in 11 BC, and that in 10 BC they moved out of an area where the Romans had permitted them.
To the north of the Chatti, Tacitus places the large area of the Chauci. To the east, the neighbours of the Chatti and Chauci were the Cherusci, who Tacitus describes as excessively peace-loving in his time.
After the early 3rd century AD, however, the Chatti virtually disappear from the sources and are only called upon as a topical element or when writing about events of the 1st century. Cassius Dio is most likely not only the first author to mention the Alamanni but also the last one to record an actual historical appearance of the Chatti. Writing about the Germanic war of Caracalla in 213 AD, he has the emperor fight "Κέννους, Kελτικòν ἔθνος" ("the Kenni, a Celtic people"). However, this is taken from an excerpt of Dio in the writings of Joannes Xiphilinus, whereas the Fragmenta Valesiana actually refer to the same people as "Chattoi". The usage of "Kελτικός" for Germanic peoples was an archaic tradition among Greek writers.
After Cassius Dio, the name "Chattus" appears among others in a panegyric by Sidonius Apollinaris in the late 5th century, now as a poetic synonym for "Germanus". The last ancient source to mention the Chatti, if only in a quotation of Sulpicius Alexander describing events of the late 4th century, was Gregory of Tours.
The extremely large timescale of Prehistoric Europe left stone tools and weapons dating from the Paleolithic to the Iron Age that were chronologically ordered and dated in the nineteenth and twentieth centuries. Tribes such as the Chatti, Cimbri and Langobardi have not been well distinguished until relatively recently.
The Chatti successfully resisted incorporation into the Roman Empire, joining the Cheruscan war leader Arminius' coalition of tribes that annihilated Varus' legions in 9 AD in the Battle of the Teutoburg Forest. Germanicus later, in 15, raided their lands in revenge, but Rome eventually responded to the Chatti's belligerent defense of their independence by building the limes border fortifications along the southern boundary of their lands in central Hesse during the early years of the 1st century. A major raid by the Chatti into Germania Superior was defeated decisively by the legions in 50 AD. Roman sources identify the fabled Mattium, beyond the Eder, as the capital of the Chatti. Destroyed by Germanicus, its location is not known today but generally assumed to be in the wider neighbourhood of Fritzlar north of the river Eder.
According to Tacitus in his book Germania (chapter 30), they were disciplined warriors famed for their infantry, who (unusually for Germanic tribes) used trenching tools and carried provisions when at war. Their neighbours to the north were the Usipi and Tencteri.
In 723, the Anglo-Saxon missionary Winfrid—subsequently called St. Boniface, Apostle of the Germans—proselytizing among the Chatti, felled their sacred tree, Thor's Oak, near Fritzlar, as part of his efforts to compel the conversion of the Chatti and the other northern Germanic tribes to Christianity.
Chasuarii and Chattuarii 
Two tribes in northern Germany have names which are sometimes compared to the Chatti. The Chattuarii who name appears to mean that they are dwellers upon the Chatti lands, or else Chatti people, lived near the Rhine, probably between Ijssel and Lippe. They came to be seen as Franks and apparently moved over the Rhine as a Frankish people, to settle into the corner of land between the Rhine and Maas rivers.
The name of the Chattuarii is in turn sometimes compared to another people called the Chasuarii mentioned by several classical authors. The Chasuarii were a Germanic tribe mentioned by Tacitus in the Germania. According to him, they dwelt to the north of the Chamavi and Angrivarii, who dwelt in turn to the north of the Bructeri, between Ems and Weser. However the name of the Chasuarii is most often interpreted to mean "dwellers on the Hase [river]", a tributary to the Ems. The 2nd century geographer Claudius Ptolemy mentions that the Kasouarioi lived to the east of the Abnoba mountains, in the vicinity of Hesse, but this account of northern Europe is thought to contain confusions derived from using different sources.
