Spain in the eleventh century 161
who seized power in Cordoba in 1009,asaconsequence of which the count was
able to recover a number of fortresses along the Duero valley, including Gormaz,
San Esteban, Clunia and Osma, which had previously been lost to al-Mansur.

Beyond Castile lay the Basque country and the diminutive kingdom of
Pamplona, or Navarre. Although its early history is obscure in the extreme, a
recognizably independent realm based upon the old Roman town of Pamplona
had emerged from first Muslim and then Frankish lordship by the second
quarter of the ninth century.
17
Under the rule of Sancho Garc
´
es I (905–25)ofthe
newly installed Jim
´
enez dynasty, the kingdom had undertaken a comparatively
modest expansion of its frontiers into the fertile region of the Rioja. It was in the
opening decades of the eleventh century, however, that the Navarrese kingdom
was to experience the most spectacular, if ultimately short-lived, extension
of its boundaries. Sancho Garc
´
es III (1004–35), known to posterity as ‘the
Great’, combined ruthless opportunism and not inconsiderable diplomatic
skill, backed up by military force, to bring an impressive array of Christian-held
territories under his rule.
18
To the east, he annexedthe central Pyrenean counties
of Sobrarbe and Ribagorza, whilst to the north he extended his lordship over
the Basque coastal regions of Guip
´
uzcoa and Vizcaya and for a very brief
period towards the end of his reign even claimed authority over Gascony.
19
To the west, meanwhile, Sancho skilfully used marriage alliances to extend
his interests yet further: thus, he himself wed Mayor S
´
anchez, the daughter of
Count Sancho Garc
´
es of Castile; he married off his sister Urraca to Alfonso V
of Le
´
on in 1023; and when his youthful brother-in-law Count Garc
´
ıa S
´
anchez
of Castile (1017–29) was murdered in 1029, thereby frustrating a proposed
Leonese–Castilian alliance, Sancho installed his own son Fernando as count
and then betrothed the latter to Sancha, the sister of Vermudo III of Le
´
on, in
1032.Hefollowed up this diplomatic coup by establishing a protectorate over
the kingdom of Le
´
on. Towards the end of his reign, by which time he claimed
to exercise hegemony over a vast area stretching from Zamora to Gascony by
way of Barcelona, Sancho was proudly styling himself emperor (imperator) and
king of the Spains (rexHispaniarum).
20
However, his much-vaunted empire
was dismembered almost as soon as it came into being. Navarrese claims to
authority over Le
´
on and Gascony evaporated within months of Sancho’s death
