Barons and castellans · Other imperial lands · as at first light, 1 January 1200

Thoire-Villars

The barons of Thoire, from their castles in the gorge of the Ain in the Bugey, and of Villars, in the fish-pond country of the Dombes, answer to the emperor as king of Arles and to no one in practice.

Their lands are flat Dombes ponds on one side and Jura valleys on the other, and they live from tolls on the roads from Lyon towards the Bresse and Geneva. This record is drawn on thin evidence and should be checked before play.

Who he is

Title
Lords (sires) of Thoire and of Villars
Since
not pinned
Born
not pinned
Family
Two baronial houses of the imperial side of the Saône, Thoire in the Bugey and Villars in the Dombes, joined by marriage in the late 12th century (date not pinned).
Confidence
low

We could not read a source on the house in this session; the OMNIA board names it as the house that holds the Dombes and much of the Bugey, and Montluel's history names it as the lord of Trévoux.

Overlord

The Empire in law (the kingdom of Arles); no king is obeyed in practice.

What it holds

  • Thoire and Matafelon: the ancestral castles in the gorge of the Ain
  • Montréal and the Oignin valley in the high Bugey (castle attested in later sources; tenure in 1200 not pinned)
  • Villars in the Dombes, with Trévoux on the Saône (named by Montluel's history as a Thoire-Villars neighbour; date not pinned)

How it was acquired

Inherited; the union of the two houses by marriage is of the late 12th century (not pinned).

Allies and rivals

Rivals of the sires of Montluel and of Beaujeu in the Dombes; neighbours of the Cluniac priory of Nantua and the abbey of Saint-Oyend in the Bugey.

How things stand that morning

Holding their castles; no side in the throne war recorded.

Wealth

Tolls on the roads from Lyon to the Bresse and Geneva; carp and grain of the Dombes; Jura timber and pasture.

Military

Castles at Thoire, Matafelon, Montréal and Villars; no war recorded for 1198-1199.

Threats

  • Savoy's old claim to the Bugey
  • Beaujeu and Montluel in the Dombes

Places of note

  • Villars: Seat of the Villars

Where the sources disagree

Evidence: Drawn from general knowledge and the campaign board; no dated source read for 1200.

"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.

On the map: Low confidence throughout; drawn round the known castles.
