Bigorre

Bigorre is the county of the Adour's upper plain and the high valleys of the Lavedan, Bareges and Campan, with Tarbes as its seat, Lourdes as its key castle and the Fors of Bigorre as its law.

Its heiress Petronilla, about fifteen, is married to Gaston VI of Bearn, who governs it as count by the king of Aragon's grant. Her father Bernard IV of Comminges, who seized the county and put away her mother in 1192, was made to give it up by Alfonso II. For the campaign this is a county held by a husband for a girl-wife, under a foreign overlord, with a dispossessed father next door.

French Wikipedia (Petronille de Bigorre; Bernard IV de Comminges; Gaston VI de Bearn) and FMG. Bernard IV married Beatrix in 1180, seized Bigorre and separated from her in 1192; Alfonso II, as suzerain of Bigorre, made him give it up in favour of his daughter and betrothed her to Gaston. Petronilla herself appears in no Bigorre act of these years: Gaston rules.

Overlord

Peter II of Aragon, suzerain of Bigorre (his father Alfonso II disposed of the county in 1192).

What it holds

  • Tarbes, the count's city and castle beside the bishop's cathedral
  • The castle of Lourdes, key to the Lavedan valleys
  • Bagneres, Vic and the plain of the Adour
  • Overlordship of the viscounts of Lavedan and of the valley communities (Bareges, Azun, Campan)

How it was acquired

Bigorre passed to the viscounts of Marsan by Peter of Marsan's marriage to the heiress Beatrix in the 1140s; then to Petronilla's mother Beatrix (Stephanie), heiress of Count Centulle III; Bernard IV of Comminges held it 1180-1192 as her husband; Gaston VI since 1192.

Allies and rivals

Gaston VI of Bearn, her husband and the real ruler. Peter II of Aragon, overlord. Bernard IV of Comminges, her father, who lost the county in 1192 and has every reason to want it back. The viscount of Lavedan and the mountain valleys. Neighbours: the viscounts of La Barthe in the Four Valleys to the east, Astarac and Pardiac to the north-east.

How things stand that morning

Held by Gaston VI in right of his wife, under Aragon. The marriage is childless; Petronilla is absent from the county's acts.

Wealth

Pastoral wealth of the high valleys and the transhumance; the markets of Tarbes, Vic and Bagneres; the hot springs of Bagneres; tolls on the roads to the passes.

Military

Castles of Lourdes and Tarbes; the levy of the valleys under the Fors of Bigorre.

Threats

  • Bernard IV of Comminges's claim through his daughter
  • The childlessness of the marriage: at Gaston's death the county's marriage becomes a prize for Aragon and its enemies
  • Valley communities jealous of their customs

What the year holds

What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

  1. 1214 (after the year)Gaston VI dies childless; the king of Aragon marries Petronilla to Nuno Sanchez, and in 1216 she is married to Guy de Montfort.Depends on: Gaston's death without heirs. Stopped by: A child of the marriage.

Places of note

  • Castle of Lourdes: Key castle of the county, guarding the Lavedan.
  • Tarbes: Count's seat and bishop's city.
  • Bagneres: Market and hot springs.

Where the sources disagree

  • FMG names the mother Beatrix III; some older lists call her Stephanie. FMG places the transfer of Bigorre to the Comminges line at about 1200; French Wikipedia gives Petronilla as countess from 1194 and Gaston as invested in 1192. We follow the Wikipedia and FMG charter dates (1192 investiture, 1196 marriage).

Evidence: The dynastic facts are well attested; the day-to-day government of the county in 1199-1200 is thinly documented.
