Álvaro Núñez de Lara (died 1287)
Castilian nobleman

Álvaro Núñez de Lara (c. 1261 – 1287) was a Castilian nobleman, the son of Juan Núñez I de Lara, head of the House of Lara, and his first wife, Teresa Álvarez de Azagra.
Family origins
He was the son of Juan Núñez I de Lara, head of the House of Lara, and his first wife, Teresa Álvarez de Azagra, Lady of Albarracín. His paternal grandparents were Nuño González de Lara "el Bueno", head of the House of Lara, and his wife Teresa Alfonso; his maternal grandparents were Álvaro Pérez de Azagra, Lord of Albarracín, and his wife, Inés, illegitimate daughter of King Theobald I of Navarre. His half-brothers, born to his father's second wife, were Juan Núñez II de Lara, head of the House of Lara; Nuño González de Lara; Teresa Núñez de Lara y Haro, and Juana Núñez de Lara.
Biography
His exact date of birth is unknown, although it must have been around the year 1261. Genealogist Luis de Salazar y Castro asserted in his writings, presenting evidence thereof, that Álvaro Núñez de Lara was not the son of Juan Núñez I, but of his brother. Nonetheless, this assertion has been refuted by several modern historians based on the records of the time.
In 1282 Álvaro Núñez de Lara supported Infante Sancho, who had revolted against his father, King Alfonso X of Castile, in dispute of his father's naming Alfonso de la Cerda heir to the throne. Álvaro joined infante Sancho when the latter set out from Córdoba to put down the revolt of the city of Badajoz, which had earlier supported infante Sancho.
This brief starts where responsible research should: with the source description of “Álvaro Núñez de Lara (died 1287)” as castilian nobleman. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as castilian nobleman. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 21, 2026. The linked authority identifier is Q129912. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1261, 1287 and 1282.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
