Garci Lasso de la Vega I

Garci Lasso de la Vega I, also known as "el Viejo" (d. 1328,[1] Soria) was a Spanish noble in the service of King Alfonso XI of Castile.

He later became the chief justice of the king and gained vast properties in Asturias de Santillana and feudal land tenures and vassal towns in more than fifteen areas throughout Castile.

He went to Soria in 1328 to recruit allies against infante Don Juan Manuel who had been consistently violating the king's territories.

The Spanish nobles of Soria assaulted him with crossbows, driving de la Vega to seek cover at the Convent of San Francisco where he was eventually killed.
