The Gisonen were Hersfeld's advocates and the office passed with Hedwig of Gudensberg to the Ludowingians.
The advocate holds the high justice over the abbey's people and land and has used it to take abbey property for himself: Henry Raspe II pushed Melsungen out of Hersfeld's hands. Abbot Siegfried quarrelled with Landgrave Louis III over the advocacy and Barbarossa settled it at Erfurt in 1182. Hersfeld's lands reach into Thuringia (Arnstadt; Herrenbreitungen since 1192).

Wealth
Advocacy dues and court fines.
Military
None of its own beyond the landgrave's.
Threats
- A new abbot who presses the abbey's rights
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.
- 1200 (not pinned)Abbot Siegfried's abbacy ends (his dates are given as 1180-1200); a new abbot is chosen, a chance for the advocate to press his rights.Depends on: Siegfried's death or resignation in 1200 Stopped by: Siegfried living on
Places of note
- Hersfeld abbey: Imperial abbey (Church map record)
Where the sources disagree
- The ADB says the Hessian lands and the Hersfeld advocacy had gone to Henry Raspe (III) as a cadet's share; after his death in 1180 they came back to the main line.
Evidence: The office is well attested; the extent of the advocacy in 1200 is not.
On the map: Indicative.
