CHATTI, an ancient German tribe inhabiting the upper reaches of the rivers Weser, Eder, Fulda and Werra, a district approximately corresponding to Hesse-Cassel, though probably somewhat more extensive.
The Werra and Fulda are both navigable when they unite to form the Weser, the Fulda being canalized between Cassel and the town of Fulda for a distance of 17 m.; the Aller, Wiimme, Geeste and Hunte are also navigable.
This Hatto built the church of St George on the island of Reichenau, was generous to the see of Mainz and to the abbeys of Fulda and Reichenau, and was a patron of the chronicler Regino, abbot of Priim.
The Fulda rises in the Wasserkuppe (3117 ft.), an eminence of the Rhdngebirge, the highest in the province.
It existed as a town as early as the 11th century, and in 1259 it was sold by the abbot of Fulda to the bishop of Minden, afterwards passing under the protection of the dukes of Brunswick.
Sorau is said to have existed in 840, and to have belonged to the abbey of Fulda till the 12th century.
Priscian was quoted by several writers in Britain of the 8th century - Aldhelm, Bede, Alcuin - and was abridged or largely used in the next century by Hrabanus Maurus of Fulda and Servatus Lupus of Ferrieres.
From 1734 to 1804 Fulda was the seat of a university, and latterly many assemblies of German bishops have been held in the town.
He is also found confirming his old rival Arnulf in the see of Reims; summoning Adalbero or Azelmus of Laon to Rome to answer for his crimes; judging between the archbishop of Mainz and the bishop of Hildesheim; besieging the revolted town of Cesena; flinging the count of Angouleme into prison for an offence against a bishop; confirming the privileges of Fulda abbey; granting charters to bishoprics far away on the Spanish mark; and, on the eastern borders of the empire, erecting Prague as the seat of an archbishopric for the Sla y s.
Then after the battle of Leipzig he deserted the waning fortunes of the French emperor, and by a treaty made with Metternich at Fulda in November 1813 he secured the confirmation of his royal title and of his recent acquisitions of territory,.
