Aristocrat of the 12th century, Lord of Guipuzcoa, Alava and Vizcaya. He was born at the end of the 11th century and died about the year 1148.
Navarrese origin, thief was Íñigo Velaz son and grandson of orbit Aznariz and Aznar, first Lord of Guipúzcoa. His father was one of the most active partners of the Aragonese on Vizcaya domain, since Alfonso el Batallador, after the death of Diego López de Haro (1124), had wielded the power of the Manor without ceding it to any beneficiary of the local aristocracy, although Lope Díaz de Haro, son of Diego, appeared as such. After the death of Alfonso the Battler (1134), the hegemony of the Lords of Guipúzcoa on the Biscay was accentuated, since Ladrón Íñiguez, acting as representative of the nobility of the Basque country, attends the agreement de Vadoluengo (Sangüesa), where García Ramírez the Restorer was invested as King of Aragon. Since then, Ladrón Íñiguez spent to fight the pretensions of the Castilian monarch, Alfonso VII, which was intended to be performed on the domain of the northern lands and incorporate them into the Crown of Castile. Precisely, in the chronic Adefonsi Imperatoris is the news that Ladrón Íñiguez was taken prisoner by Alfonso VII in 1136, probably in the course of the campaign of Castilian conquest by lands of Alava. During the four years prison, his son, candle thief, maintained the Government independent of the three Basque provinces.
In 1140, Ladrón Íñiguez regained freedom, but not their effective domains. Alfonso VII, real Dominator of the politics of the time, wanted to play three bands to satisfy the local aristocracies, thereby dispossessed Ladrón Íñiguez of Alava Lordship (not of the Guipuzcoan) and handed it over to Lope Díaz de Haro. The Lords of Biscay complained at length to Alfonso VII of this irregular situation, and it even seems that he came to have strained relations between father and son in this matter. The latest preserved on Ladrón Íñiguez date back to the year 1148, which appears as "comte in Aybar, Leguin and Guipúzcoa", not in Vizcaya where the politics of Alfonso VII, consisting of achieving multiple vasallajes of the Lords of the area, left quite weakened stately power.
