García Sánchez I of Pamplona  García Sánchez I (Basque: "Gartzea I.a Santxez"; c. 919 – 22 February 970), was King of Pamplona from 925 until his death in 970. He was the second king of the Jiménez dynasty, succeeding his father when he was merely six years old. Son of Sancho I and Toda Aznárez, he succeeded his father in 925 when he was only six years old and reigned under the tutelage of his uncle Jimeno Garcés and of his mother, Toda. Three of García's sisters married kings of León: Urraca married Ramiro II; Oneca was the wife of Alfonso IV; and Sancha Sánchez was first married to Ordoño II. After Ordoño's death, she became the wife of Álvaro Herraméliz, Count of Álava, and after his death married Fernán González, Count of Castile. Another sister, Velasquita, married Munio Vélaz, who was Álvaro Herraméliz's predecessor as count of Álava. According to historian Gonzalo Martínez Díez, "the intimate family ties of the Navarrese dynasty with the monarchs of León and with the counts of Castile and Álava, would be reflected in the battlefield where soldiers from Pamplona frequently fought side by side with the Leonese and Castilians against a common enemy, Islam". Thanks to this web of alliances crafted by Queen Toda, Pamplona was able to increase its power and play a key role in the affairs of the Christian kingdoms of the Iberian Peninsula. Upon the death of his uncle and tutor, Jimeno Garcés, on 29 May 931, another uncle, Íñigo Garcés, half-brother of García's father, Sancho I, probably tried to become the regent of the kingdom and perhaps even usurp the throne, to the detriment of his nephew's rights. Both García and his mother Toda appear in a charter at the Abbey of San Pedro de Siresa on 9 March 933 without the royal titles. A year later, in May 934, the Caliph of Córdoba, Abd-ar-Rahman III, led a military expedition against King Ramiro II of León.
