Convention of Gramido

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 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.

Captured weapons were surrendered peacefully, and the Allies committed to advocating for improved conditions for former Royalist army officers.

This resentment led to punitive actions against the opposition, fostering political instability that contributed to the outbreak of the Regeneration (Regeneração) in 1851.
