The abbey founded by the emperor Louis II on an island in the Pescara once held lands from the Adriatic to the Maiella and the Trigno.
By 1200 its lordship has shrunk to the 'island' of Casauria in the Pescara gorge and a few villages around it, wedged against the county of Manoppello, which Henry VI gave in 1195 to the brothers of the chancellor Walter of Palear.
Who holds it
- Name
- Not pinned (Gioele, abbot after 1182, is the last named in the sources consulted)
- Title
- Abbot of Casauria
- Since
- Not pinned
- Confidence
- low
Abbot Leonate (1156-about 1182) rebuilt the church from 1176, with papal protection against Norman pressure; his successor Gioele carried the work on after 1182 (it.wikipedia). The abbey's own chronicle, the Chronicon Casauriense, stops in 1182, so the abbot on 1 January 1200 is not pinned.
What it holds
- The 'insula' of Casauria in the Pescara gorge, with the abbey (it.wikipedia)
- Alanno and nearby villages, still the abbey's in the 14th century (it.wikipedia) [held in 1200 likely, not pinned]
- Older claims over castles of the Pescara valley (Pescosansonesco, Bolognano, Tocco) [thin]
How it was acquired
Founded in 871 by Louis II; at its height in the 11th century its lands ran from the Adriatic coast to the Maiella and the Pescara and Trigno rivers. Count Ugo Malmozzetto of Manoppello ravaged it in 1076; by the 14th century only the island of Casauria, Alanno, Castel Valignano and Castelvecchio Monacisco were left (it.wikipedia).
How things stand that morning
A reduced abbatial lordship [thin].
Wealth
The Pescara gorge, through which the road from Rome to the Adriatic passes at the abbey's gates; mills and pasture.
Threats
- The Pagliara counts of Manoppello next door
- The regency war in the Abruzzi
Advocates and rivals
The counts of Manoppello, since April 1195 Walter of Palear's brothers Gentile and Manerio (DBI); the lords of the Pescara valley; the papacy as protector.
Places of note
- San Clemente a Casauria: The abbey church with Leonate's portico
Where the sources disagree
Evidence: Its decline is documented; its abbot and holdings in 1200 are not.
On the map: The held core follows the abbey's 14th-century remnant, which it surely held in 1200 as well; the claimed castles show the older lordship.
