Name
The German name ''
Hessen'', like the names of other German regions (''Schwaben'' "Swabia", ''Franken'' "Franconia", ''Bayern'' "Bavaria", ''Sachsen'' "Saxony"), derives from the dative plural form of the name of the inhabitants or
eponymous tribe, the Hessians (''Hessen'', singular ''Hesse''). The geographical name represents a short equivalent of the older compound name ''Hessenland'' ("land of the Hessians"). The
Old High German form of the name is recorded as ''Hessun'' (dative plural of ''Hessi''); in
Middle Latin
Medieval Latin was the form of Literary Latin used in Roman Catholic Church, Roman Catholic Western Europe during the Middle Ages. In this region it served as the primary written language, though local languages were also written to varying deg ...
it appears as ''Hassia'', ''Hessia'', ''Hassonia''. The name of the Hessians ultimately continues the tribal name of the ''
Chatti''.
The ancient name ''Chatti'' by the 7th century is recorded as ''Chassi'', and from the 8th century as ''Hassi'' or ''Hessi''.
An inhabitant of Hesse is called a "Hessian" (German: ''
Hesse'' (masculine), plural ''Hessen'', or ''Hessin'' (feminine), plural ''Hessinnen'').

The English form ''Hesse'' was in common use by the 18th century, first in the hyphenated names of the states of ''Hesse-Cassel'' and ''Hesse-Darmstadt'', but the latinate form ''Hessia'' remained in common English usage well into the 19th century.
The
European Commission uses the German form ''Hessen'', even in English-language contexts, due to the policy of leaving regional names untranslated.

History
The territory of Hesse was delineated only in 1945, as
Greater Hesse, under
American occupation. It corresponds only loosely to the medieval
Landgraviate of Hesse.
In the 19th century, prior to the
unification of Germany, the territory of what is now Hesse comprised the territories of

Early history
The Central Hessian region was inhabited in the
Upper Paleolithic.
Finds of tools in southern Hesse in Rüsselsheim suggest the presence of Pleistocene hunters about 13,000 years ago. A
fossil hominid skull that was found in northern Hesse, just outside the village of Rhünda, has been dated at 12,000 years ago.

ic presence in what is now Hesse is indicated by a mid-5th-century BC
La Tène-style burial uncovered at
Glauberg. The region was later settled by the
Germanic Chatti tribe around the 1st century BC, and the name ''Hesse'' is a continuation of that tribal name.
The
ancient Romans had a military camp in Dorlar, and in Waldgirmes directly on the eastern outskirts of Wetzlar was a civil settlement under construction. Presumably, the provincial government for the occupied territories of the right bank of Germania was planned at this location. The governor of Germania, at least temporarily, likely had resided here. The settlement appears to have been abandoned by the Romans after the devastating
Battle of the Teutoburg Forest failed in the year AD 9. The Chatti were also involved in the
Revolt of the Batavi in AD 69.
Hessia, from the early 7th century on, served as a buffer between areas dominated by the
Saxons (to the north) and the

and up to the rivers Diemel and Weser. To the west, it occupies the valleys of the rivers Eder and Lahn (the latter until it turns south). It measured roughly 90 kilometers north–south, and 80 north-west.
The area around Fritzlar shows evidence of significant pagan belief from the 1st century on. Geismar was a particular focus of such activity; it was continuously occupied from the Roman period on, with a settlement from the Roman period, which itself had a predecessor from the 5th century BC. Excavations have produced a
horse burial and bronze artifacts. A possible religious cult may have centered on a natural spring in Geismar, called ''Heilgenbron''; the name "Geismar" (possibly "energetic pool") itself may be derived from that spring.
The village of , now a part of
Gudensberg near Fritzlar and less than ten miles from Geismar, was likely an ancient religious center; the basaltic outcrop of Gudensberg is named after Wodan, and a two-meter tall
quartzite megalith called the ''
Wotanstein'' is at the center of the village.
By the mid-7th century, the Franks had established themselves as overlords, which is suggested by archeological evidence of burials, and they built fortifications in various places, including
Christenberg. By 690, they took direct control over Hessia, apparently to counteract expansion by the Saxons, who built fortifications in

across the river Diemel, the northern boundary of Hessia. The
Büraburg (which already had a Frankish settlement in the sixth century) was one of the places the Franks fortified to resist the Saxon pressure, and according to John-Henry Clay, the Büraburg was "probably the largest man-made construction seen in Hessia for at least seven hundred years". Walls and trenches totaling one kilometer in length were made, and they enclosed "8 hectares of a spur that offered a commanding view over Fritzlar and the densely-populated heart of Hessia".

Hesse-Kassel (or Hesse-Cassel),
Hesse-Darmstadt,
Hesse-Rheinfels, and the also previously existing
Hesse-Marburg. As the latter two lines died out quite quickly (1583 and 1605, respectively), Hesse-Kassel and Hesse-Darmstadt were the two core states within the Hessian lands. Several collateral lines split off during the centuries, such as in 1622, when
Hesse-Homburg split off from Hesse-Darmstadt, and in 1760 when
Hesse-Hanau split off from Hesse-Kassel. In the late 16th century, Kassel adopted
