# Diego Sarmiento: The Spanish Diplomat Who Shaped Anglo-Spanish Relations A Valladolid exhibition honors the Count of Gondomar, a pivotal figure in 17th-century European diplomacy. - **Source:** [El Confidencial – España](https://www.elconfidencial.com/espana) - **Published:** 2026-11-09 - **Topic:** [politics](https://brifing.si/c/politics) - **Original article:** - **On Brifing:** https://brifing.si/s/872e9119-4fe9-4375-affb-834aeaec5e21 ## Forgotten Diplomatic Hero Diego Sarmiento, the first Count of Gondomar, served as a crucial Spanish ambassador to England during the early 17th century. While his efforts secured a rare period of peace between the two nations, his legacy remains largely overlooked in Spain. A new exhibition in Valladolid now seeks to rectify this historical oversight. ## Exhibition at Casa del Sol The National Museum of Sculpture in Valladolid hosts the exhibition titled Times of Peace and Diplomacy. Located in the historic Casa del Sol, the former residence of the Gondomar family, the display highlights the count's life and his wife Constanza de Acuña's essential role in managing complex international relations and royal connections. ## Influence on King James I Appointed by the Duke of Lerma in 1613, Sarmiento quickly gained the trust of King James I through his erudition and intelligence. This close relationship fueled intense resentment among English Protestants, who viewed the Spanish diplomat with deep suspicion. His influence eventually led to the execution of the English naval hero Walter Raleigh. ## The Spanish Match Failure Sarmiento orchestrated the Spanish Match, a proposed marriage between the Spanish Infanta Maria and the future King Charles I. The prince traveled to Madrid incognito to finalize the agreement, but the engagement collapsed due to religious requirements and shifting political tides. This failed alliance remains a famous episode in Spanish historical fiction. ## Propaganda and Public Image Following his role in Raleigh's execution, English propaganda vilified Sarmiento, often labeling him the Spanish Machiavelli. He was even caricatured as the Black Knight in the play A Game of Chess. Despite this hostility, he maintained his diplomatic duties, protecting Catholic citizens in England, including the noblewoman Luisa de Carvajal y Mendoza. ## Cultural and Scholarly Legacy The Gondomar family amassed one of the world's most significant private libraries, containing over 10,000 volumes, now largely housed in the Royal Palace. During his time as corregidor in Valladolid, Sarmiento was celebrated by literary giants like Cervantes, Quevedo, and Lope de Vega, who frequently referenced his notable administrative and political achievements. ## Diplomatic Artifacts on Display The exhibition features original peace treaties preserved in the Archivo de Simancas and a detailed letter from Sarmiento describing the English court. Visitors can also view a replica of the Vulnerata, a religious statue mutilated during the English sack of Cadiz, symbolizing the violent context surrounding these fragile diplomatic efforts. ## The Fragility of Peace The peace established by Sarmiento lasted only twenty years, serving as a brief oasis amidst centuries of conflict. The agreement ultimately dissolved after the death of King James I and the ascension of Charles I, coupled with the rise of the Count-Duke of Olivares, who favored a more aggressive foreign policy stance. ## Historical Significance Today The exhibition, running until February 14, serves as a reminder that diplomatic successes are rarely permanent. By honoring the Count of Gondomar, the museum highlights the importance of dialogue in turbulent times. It encourages a deeper understanding of the complex, often adversarial, historical relationship between the Spanish and English crowns. ## Sources covering this story - https://www.elconfidencial.com/espana/castilla-y-leon/2026-11-09/el-conde-de-gondomar-el-heroe-de-la-diplomacia-al-que-todavia-odian-los-ingleses-y-que-espana-ignora_4460619/ — --- _Summary written by Brifing from the original reporting.
