Boniface's abbey of Fulda is the greatest monastery of the Empire.
Its abbots have counted as princes of the Empire since 1170 (the formal title of prince-abbey follows in 1220), and in the 12th century its lands were the largest of any abbey in the Empire. Around the abbey lies a compact lordship in the old Buchonia forest, with outlying centres such as Hünfeld and Hammelburg; the counts of Ziegenhain are its high advocates.
Who holds it
- Name
- Heinrich III of Kronberg
- Title
- Abbot of Fulda, prince of the Empire
- Since
- 1192
- Confidence
- high
Abbot 1192-1216, in the list of Fulda's abbots between Konrad II (1177-1192) and Hartmann I (1216-1217). His stance in the throne war is not pinned in the sources consulted.
What it holds
- Fulda: the abbey with Boniface's tomb and the market town that grew at its gate
- The lordship around Fulda in the Buchonia, the abbey's oldest and most compact block
- Hünfeld: the abbey's collegiate church and market to the north
- Hammelburg on the Franconian Saale: an old Fulda estate centre (from the abbey's earliest endowments)
- Vast scattered estates across Hesse, Thuringia and Franconia, much of them held by vassals and ministerials
How it was acquired
Royal and noble endowments from the 8th century on, around Boniface's tomb (754). Princely rank from 1170; formal princely abbey from 1220.
How things stand that morning
Heinrich holds the abbey and its lands; the extent of real lordship outside the Fulda block is uncertain because so much is enfeoffed.
Wealth
Estates and rents across Hesse, Thuringia and Franconia; pilgrims to Boniface's tomb; the Fulda market and the roads from Frankfurt to Thuringia.
Threats
- The Ziegenhain advocates
- Alienation of estates to vassals
- The armies of the throne war crossing between the Rhine and Thuringia
Advocates and rivals
The counts of Ziegenhain, high advocates of the abbey; the abbey's own ministerials, who hold much of its land; the Thuringian landgraves and the bishop of Würzburg as neighbours; the townsmen of Fulda, who will later storm the abbot's castles with the advocate's help.

Where the sources disagree
Evidence: The abbot and the abbey's princely status are attested; the bounds of the Fulda block in 1200 are not, so it is drawn as town territories around the main centres. Hammelburg is from general knowledge of the abbey's early endowments. The drawing uses the fuller list of abbey places gathered for the eastern region.
On the map: The core block is drawn as a 12 km territory around Fulda; the real 1200 lordship had no fixed border and the outlying estates are not drawn.
