Counts · Nevers, Auxerre, Tonnerre · as at first light, 1 January 1200

Nevers

The county of Nevers on the Loire and the Allier, from La Charite and Clamecy to Decize and the edge of the Bourbonnais, with the Morvan to the east.

It came to Herve IV of Donzy in October 1199 as the dowry of Mahaut of Courtenay, the heiress, when her father Peter of Courtenay had to buy his freedom after Herve beat and captured him near Cosne. Herve, a vassal who has defeated his lord and kept the king's goodwill, now rules the county in the name of an eleven-year-old wife.

fr.wikipedia Herve IV de Donzy and Mathilde de Courtenay (from Medieval Lands and Lespinasse)

Overlord

Philip II, king of France

What it holds

  • Nevers city and castle, with the bishop of Nevers
  • Decize on its Loire island
  • Clamecy and the Vaux d'Yonne
  • Moulins-Engilbert and the Bazois
  • the comital guard over the priory of La Charite and the claim to rights at Vezelay
  • fiefs of the Morvan (Chateau-Chinon, Lormes: holders not pinned)

How it was acquired

1199 marriage settlement, approved by Philip Augustus.

Allies and rivals

Herve: favoured by the king; rival of his father-in-law Peter of Courtenay; neighbour of the duke (who later cedes him Liernais, 1210) and of the Bourbon lords to the south.

How things stand that morning

Held and ruled by Herve from Nevers and Donzy. Across the Loire to the west lies royal Berry (see the Royal researcher); Gien, downstream, has been royal since 1199; the Bourbonnais lies across the Allier to the south; the duchy of Burgundy lies beyond the Morvan.

Wealth

Loire traffic and tolls at Nevers, Decize and La Charite; iron of the Nivernais; wood and cattle of the Morvan.

Military

Nevers walled by Peter of Courtenay in the 1190s (date not pinned here); Decize castle; Herve's Donziais knights.

Threats

  • Peter of Courtenay's grievance
  • the missing papal dispensation for the marriage

Places of note

  • Nevers castle: comital seat
  • Decize: comital castle on a Loire island
  • Clamecy: comital town on the Yonne

Where the sources disagree

  • Bouchard (1987), as cited in en.wikipedia's Herve IV, dates the marriage to 1200; October 1199 is followed (see the realm record).

Evidence: The transfer is well attested by year; the castellanies drawn follow the later county.

On the map: Church lordships inside (La Charite, Vezelay, the bishop of Nevers's Premery, Corbigny) come from the Church map; the Morvan fiefs are approximate.
