Abbeys and priories · Kingdom of Sicily under the regency · as at first light, 1 January 1200

Montevergine

The mountain abbey above Avellino, mother house of the congregation founded by William of Vercelli, is a new lord: in March 1195 Henry VI gave its abbots baronial powers over the land of Mercogliano below the sanctuary.

On 1 January 1200 it holds that small barony in a war zone: Markward besieged Avellino, a few miles away, in 1199 before coming to terms with its people (Richard of San Germano).

Who holds it

Confidence
low

On 30 March 1195, at an assembly in Bari, Henry VI, with Constance, granted the abbots baronial powers over the territory of Mercogliano, with fiscal exemptions; Constance is said to have visited the abbey and given it a silver imperial image. Frederick II issued 26 documents in its favour between March 1206 and 1250, the first granting a plot of the royal demesne at Maddaloni (Federiciana).

What it holds

  • Mercogliano: baronial powers over its territory, granted by Henry VI at Bari on 30 March 1195 (Federiciana)
  • The sanctuary on Monte Partenio and the abbey's hospice
  • Fiscal exemptions granted in 1195 (Federiciana)

How it was acquired

Founded by William of Vercelli in the early 12th century; the barony of Mercogliano came from Henry VI and Constance in 1195; more grants followed from Frederick II after 1206 (Federiciana).

How things stand that morning

Held by the abbot.

Wealth

Pilgrims to the sanctuary of the Virgin; the land of Mercogliano; the congregation's dependent houses.
