Basque leader, considered the first king of Pamplona.

He is thought to have risen to prominence after the defeat of local Frankish partisans at the Battle of Pancorbo in 816, and his rule is usually dated from shortly after the defeat of a Carolingian army in 824.

He is first attested by chroniclers as a rebel against the Emirate of Córdoba from 840 until his death a decade later. Remembered as the nation's founder, he would be referred to as early as the 10th century by the nickname "Arista", coming either from Basque Aritza (Haritza/Aiza, literally 'the oak', meaning 'the resilient') or Latin Aresta ('the considerable').

The name of the wife (or wives) of Íñigo is not reported in contemporary records, although sources from centuries later assign her the name of Toda or Onneca.[13] There is also scholarly debate regarding her derivation, some hypothesizing that she was daughter of Velasco, lord of Pamplona (killed 816), and others making her kinswoman of Aznar I Galíndez.

The dynasty founded by Íñigo reigned for about 80 years, being supplanted by a rival dynasty in 905. However, due to intermarriages, subsequent kings of Navarre descended from Íñigo, and some accounts even wrongly showed them to descend from Íñigo in the direct male line. He is remembered as the founder of the nation of Navarre.
