Guipúzcoa (Castilian since 1199)

Guipúzcoa, the Basque land between the Deba and the Bidasoa, was Navarre's window on the sea, with San Sebastián (fuero from Sancho VI about 1180, settled by Gascon shipmen and merchants from Bayonne) as the kingdom's port.

During the 1199 campaign it went over to Alfonso VIII: the castles Castile counts among its gains are San Sebastián, Fuenterrabía, Beloaga (above Oiartzun), Aitzorrotz (in Léniz) and Ausa. Later Guipúzcoan tradition calls it a free submission for the sake of trade with Castile; modern work sees a conquest made easy by the local nobility's choice. On 1 January 1200 it is Castilian-held, Castile's new outlet to the sea, and Navarre has no port left.

Who he is

Name
Alfonso VIII of Castile, through tenentes not pinned for 1 January 1200 (Diego López de Haro holds San Sebastián by 11 October 1200 and Aitzorrotz after 1200)
Title
Land of Guipúzcoa (Ipuzcoa), Navarrese until 1199
Since
1199, before 27 September
Confidence
medium

A private charter of 27 September 1199 already dates by Alfonso VIII 'reigning in Castile, Álava, Campezo, Guipúzcoa and San Sebastián' (Orella, citing Balparda). The land therefore passed to Castile while Vitoria was under siege, not after its fall.

Overlord

Alfonso VIII of Castile (in fact); Sancho VII has not ceded it

What it holds

  • San Sebastián with its port and fuero
  • Castles of Fuenterrabía, Beloaga, Aitzorrotz and Ausa
  • The coastal settlements (Getaria, Motrico) and the valleys of the Oria, Urola, Deba and Léniz

How it was acquired

Navarrese since the 12th century (confirmed to Navarre in 1179); Castilian from 1199.

Allies and rivals

The Guipúzcoan nobility and the San Sebastián merchants, who now look to Castile's markets; Diego López de Haro, lord of neighbouring Vizcaya.

How things stand that morning

OCCUPIED by Castile, apparently with local consent. The Nabarlur blog claims Navarre won back the castles of Ausa and Ataun late in 1199; no scholarly summary we saw confirms it, and Jiménez de Rada lists Ausa among Castile's gains.

Wealth

The port of San Sebastián (the Navarrese and Castilian wool and wine trade, Gascon shipping), whaling (the men of Motrico owe the king a whale a year), iron and timber.

Military

Castles: San Sebastián (Urgull), Fuenterrabía, Beloaga, Aitzorrotz, Ausa. No fighting recorded.

Threats

  • A Navarrese attempt to recover the coast once Sancho returns.
  • Competing claims of Castilian magnates to its tenencias.

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.

In 1200

  1. January to March 1200Eleanor of Aquitaine travels through Guipúzcoa on her Castilian journey (Orella).Depends on: The Anglo-French settlement going ahead. Stopped by: Its collapse.
  2. October 1200Alfonso VIII confirms the fueros of Guipúzcoa (Dulska's summary).Depends on: Castilian control. Stopped by: A Navarrese recovery.
  3. by 11 October 1200Diego López de Haro holds San Sebastián for Castile.Depends on: Haro's favour. Stopped by: His fall (1201).
  4. 31 December 1200The whale owed by the men of Motrico is granted to the Order of Santiago.Depends on: Castilian lordship. Stopped by: Nothing likely.

Later, on the likely course

  1. 18 April 1203 and 1209 (after the year)Fuenterrabía receives the fuero of San Sebastián (1203); Getaria's Navarrese grant of the same fuero is confirmed (1 September 1209); Motrico gets its charter (1209).Depends on: Castile building up the coast. Stopped by: A return to Navarre.

Places of note

  • Castle of Beloaga: Taken by Castile.
  • Castle of Aitzorrotz: Held by Pedro Ladrón (Guevara) for Navarre in 1194; taken by Castile; held by Diego López de Haro after 1200.
  • Castle of Ausa: Taken by Castile (Rada); Nabarlur claims a Navarrese recovery in 1199.
  • Castle of Fuenterrabía: Taken by Castile.

Where the sources disagree

  • Older works (Auñamendi's Sancho VII article) put the fall of Guipúzcoa after Vitoria's surrender; the September 1199 dating clause cited by Orella puts it during the siege, which we follow.

Evidence: The September 1199 dating clause, Rada's list of castles and the later Castilian charters are solid; the manner of the submission is argued over and coloured by later Guipúzcoan tradition.

On the map: The modern province is close to the medieval land but not identical (Oñati and some border valleys differ).
