Convention of Gramido
1847 peace treaty

The Convention of Gramido was an agreement signed on 29 June 1847, in the Casa Branca (White House) of Gramido, in Valbom, Portugal. It marked the conclusion of the Patuleia, a civil war between the Septembrists and the Cartistas. The Convention was signed by the commanders of the Spanish and British forces acting under the Quadruple Alliance, the representative of the Portuguese government in Lisbon, and representatives from the Junta in Porto. The agreement ended the conflict on terms that, while conciliatory in tone, solidified the Cartistas' victory and strengthened the position of Queen Maria II's government.
The agreement
The Convention was signed by representatives from the warring parties and allied powers. Lieutenant General Manuel de la Concha and Colonel Buenaga represented Spain, while Colonel Wilde acted on behalf of the United Kingdom. The Portuguese government was represented by the Marquis of Loulé and the Junta of Porto by General César de Vasconcelos.
The agreement established several provisions to ensure peace and stability. The cities of Porto and Vila Nova de Gaia were to be temporarily occupied by Spanish troops to ensure stability, with British forces stationed at strategic points such as the Fort São João Baptista da Foz and allied warships stationed in the Douro River. The allied powers guaranteed the safety and property of Porto's residents and promised honorable treatment for the defeated Junta’s officers, allowing them to retain their personal weapons and horses.

Why this record matters
The phrase “1847 peace treaty” 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.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Aug 8, 2025.

Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. 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.
