Viscounts · Crown of Aragon · as at first light, 1 January 1200

Béarn

Bearn is a compact Pyrenean viscounty of mountain valleys (Aspe, Ossau, Bareton) and foothill towns, ruled from Morlaas, with Oloron and Lescar as its two bishop's cities and, since 1193-1194, Orthez on the Gave as its door to the Landes.

Gaston VI, a Montcada by blood and a Catalan magnate by upbringing, holds it as the man of the king of Aragon. Through his wife Petronilla he is also count of Bigorre and viscount of Marsan, and he holds the Gascon viscounties of Gabardan and Brulhois of the duke. That makes him the strongest lord between the Garonne and the Pyrenees, with one foot in Eleanor's duchy and one in Peter II's court.

Confidence
high

FMG: the 1170 homage of Marie to Alfonso II, 'renewed by Vicomte Gaston VI in 1187'; Alfonso II's charter of September 1192 arranging the Bigorre marriage. French Wikipedia: invested with Bigorre by Alfonso II in 1192, married 1196, exchanged Mixe and Ostabarret with the viscount of Dax for Orthez in 1194 (FMG: Orthez and Riviere-Gave taken in 1193), made peace with the viscount of Soule in 1196.

Overlord

Peter II of Aragon for Bearn (homage of 1170 renewed in 1187). In law Bearn lies within the duchy of Gascony, but the viscounts have looked to Aragon since Marie's homage at Jaca in 1170.

What it holds

  • Morlaas, the capital and mint of the Morlaas penny, the coin of Gascony
  • Oloron and the valleys of Aspe, Ossau and Bareton, with their passes into Aragon (the Somport road)
  • Lescar and the Gave de Pau; the castle of Pau
  • Orthez and the Riviere-Gave, gained from the viscount of Dax in 1193-1194 in exchange for Mixe and Ostabarret
  • The salt springs of Salies and the town of Sauveterre
  • The Montaner border towards Bigorre (the viscounty of Montaner's status in 1200 not pinned)

How it was acquired

Inherited in 1173 from his mother Marie, heiress of the Gabarret line of Bearn; Orthez by exchange in 1193-1194.

Allies and rivals

Peter II of Aragon, his lord and kinsman. His father-in-law Bernard IV of Comminges, ousted from Bigorre by Alfonso II in 1192. The viscount of Soule, with whom he quarrelled until the peace of 1196 (the dispute was taken to Sancho VII of Navarre at Olite). The viscount of Dax-Tartas, his partner in the 1194 exchange. The duke of Aquitaine, of whom he holds Gabardan, Brulhois and Marsan.

How things stand that morning

Gaston VI holds Bearn in full. He is the vassal of Peter II, and with Bigorre his wife's, his power reaches from the Landes to the high Pyrenees. He is not at war on 1 January 1200. Across his borders: Soule and Mixe (ducal Gascony) to the west, the Landes viscounties (Tartas, Marsan, Tursan) to the north, Bigorre (his wife's) to the east, and over the Somport and the Pourtalet the kingdom of Aragon (Jaca, Tena).

Wealth

Salt of Salies; tolls on the Somport road from Oloron to Jaca and on the Gave crossings at Orthez; the mint of Morlaas; flocks and the transhumance of the valleys; the markets of Morlaas and Oloron.

Military

Castles of Morlaas, Pau, Orthez, Sauveterre and Oloron; the levy of the valleys under the Fors of Bearn; Gascon and Aragonese routiers for hire.

Threats

  • Being caught between the duke of Aquitaine and the king of Aragon
  • Church censure: he will be excommunicated for siding with Toulouse in the wars of the next decade
  • Disputes on his borders with Soule, Dax and Bigorre's neighbours

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. 1200, not pinnedNo dated event for Bearn in 1200 is known to me. Gaston's attention is on Aragon, where Peter II is preparing his coronation journey to Rome (1204) and the marriage of his sister Eleanor to Raymond VI (agreed during 1200).Depends on: Peace with his Gascon neighbours. Stopped by: A Gascon or Navarrese quarrel on his borders.

Places of note

  • Morlaas: Capital and mint of Bearn.
  • Castle of Pau: Viscount's castle over the Gave.
  • Orthez: Bridge town gained 1193-1194.
  • Salies: Salt springs.
  • Sauveterre: Castle on the Gave d'Oloron facing Mixe and Soule.

Where the sources disagree

  • FMG dates the gain of Orthez to 1193; French Wikipedia gives 1194 and says Mixe and Ostabarret were given to the viscount of Dax in exchange. Both agree Orthez is Bearnese by 1200.

Evidence: The homages to Aragon (1170, 1187), the Bigorre marriage (1192, 1196) and the Orthez exchange are well documented; the inner limits of Bearn are drawn from the later province.

On the map: Outline traced from the later province of Bearn; the Montaner border and the edges against Soule, Mixe and Tursan are approximate.
