Convention of Gramido
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.
