The Hessian half of the Ludowingian lands, inherited through Hedwig of Gudensberg, heiress of the Gisonen and of the counts Werner of Maden and Gudensberg: the county court at Maden and the castle of Gudensberg, Kassel with its town, Melsungen, Homberg, Alsfeld, Grünberg and Marburg with Biedenkopf on the upper Lahn, together with the advocacy of Hersfeld.
It is a county held of Mainz and riddled with Mainz towns (Fritzlar, Amöneburg, Hofgeismar), and the two have fought over it within living memory: Mainz troops wrecked Melsungen in 1193-94 and Grünberg in 1195.

Overlord
The archbishop of Mainz for the county itself (northern Hesse had been a Mainz fief since about 1120); the king for royal fiefs such as the land round Marburg, held through the advocacy of the Wetter canonry.
What it holds
- Gudensberg castle and the county court (Landgericht) at Maden
- Kassel: royal court of 913, Ludowingian residence from about 1143, walled, with town rights before 1189
- Melsungen: built up by Henry Raspe II as advocate of Hersfeld; sold to Archbishop Conrad of Mainz in 1189-90, wrecked in the Mainz feud of 1193-94 and rebuilt by the landgraves as their own
- Felsberg on the Eder (the Felsburg and Altenburg castles were later Hessian, facing Mainz's Heiligenberg; who held the Felsburg in 1200 is not pinned)
- Homberg (Efze): the Hohenburg, built before 1190 by the Homberg family and called the landgrave's about 1190
- Alsfeld: castle built 1180-90 on the road to Frankfurt
- Grünberg: castle first named 1186, founded by Louis III against Mainz, destroyed by Mainz troops 1195 and rebuilt as a planned town
- Marburg castle and its market settlement on the Lahn (first named 1138-39; a chartered town only from 1222-27)
- Biedenkopf castle on the upper Lahn
- The advocacy (Vogtei) of Hersfeld abbey (see Hersfeld advocacy)
- The advocacy of the Wetter canonry
How it was acquired
By the marriage of Landgrave Louis I with Hedwig of Gudensberg (died 1148): Giso IV inherited the Werner counts' lands and advocacies round Kassel, Fritzlar and Melsungen in 1121-22, and the Gisonen died out in 1137. Held by the cadet Henry Raspe II and III until 1180, since then by the landgraves themselves.
Allies and rivals
Rival: the archbishop of Mainz, lord of Fritzlar, Amöneburg and Hofgeismar and overlord of the county; at peace with him under Conrad of Wittelsbach, Sophia's uncle. Neighbours: the counts of Ziegenhain (Fulda's advocates) and his own brother Frederick of Wildungen; the counts of Waldeck and Schwalenberg to the north-west; the Battenberg and Wittgenstein counts to the west; the Wetterau lords to the south.
How things stand that morning
Held by Hermann (Staufen since 15 August 1199). The Mainz feud of 1193-95 is over; nothing is known of fighting in Hesse in 1199.
Wealth
The road from Frankfurt through Alsfeld and the Hessian plain to Eisenach; the Fulda and Eder crossings at Melsungen and Felsberg; Kassel's market; the advocacy dues of Hersfeld.
Military
Castles of Gudensberg, Melsungen, Homberg, Alsfeld, Grünberg, Marburg and Biedenkopf (and probably the Felsburg); Hessian ministeriales and Burgmannen (the Homberg family at the Hohenburg). No numbers.
Threats
- Mainz's rival lordship at Fritzlar and Amöneburg, and a contested Mainz succession in late 1200
- The quarrel of his brother Frederick with the Ziegenhain counts
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- late 1200 or 1201 (not pinned)After Conrad of Mainz dies (25 or 27 October 1200), the two Mainz claimants each seek the Hessian towns of the see; the landgrave can profit from the split.Depends on: Conrad's death on its date and a double election Stopped by: A single agreed successor
Places of note
- Gudensberg (the Obernburg): Castle of the counts in Hesse
- Maden: Ancient county court of Hesse (the Mader Heide)
- Marburg castle: Castle over the Lahn
- Grünberg castle: Rebuilt after 1195
- The Hohenburg at Homberg: Landgrave's castle held by the Homberg family
- Biedenkopf castle: Upper Lahn
Where the sources disagree
Evidence: Town and castle dates come from de.wikipedia town articles; the extent of the county in 1200 is drawn from later Hessian territory and is approximate.
On the map: Approximate: the county's 1200 extent is drawn from its castles; many villages were held by ministeriales, by Hersfeld, Fulda or Mainz, or by free lords.
