Sancho III of Pamplona
King of Pamplona and ruler of Aragon from 1004 to 1035
Sancho Garcés III (c. 992–996 – 18 October 1035), also known as Sancho the Great (Spanish: Sancho el Mayor, Basque: Antso Gartzez Nagusia), was the King of Pamplona from 1004 until his death in 1035. He also ruled the County of Aragon and by marriage the counties of Castile, Álava and Monzón. He later added the counties of Sobrarbe (1015), Ribagorza (1018) and Cea (1030), and would intervene in the Kingdom of León, taking its eponymous capital city in 1034.
He was the eldest son of García Sánchez II and his wife Jimena Fernández.
Biography
Birth and succession
The year of Sancho's birth is not known, but it is no earlier than 992 and no later than 996. His parents were García Sánchez II the Tremulous and Jimena Fernández, daughter of Fernando Bermúdez, count of Cea on the Leonese frontier. García and Jimena are first recorded as married in 992, but there is no record of their son Sancho until 996. The first record of the future king is a diploma of his father's granting the village of Terrero to the monastery of San Millán de la Cogolla. The king describes Sancho merely as "my son" (filius meus).

Why this record matters
The phrase “king of Pamplona and ruler of Aragon from 1004 to 1035” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
