The Battle of Ponte Ferreira, fought on 22–23 July 1832, was the first major battle of the Portuguese Civil War between the forces of Dom Pedro, ex-Emperor of Brazil and Regent for his daughter Maria da Glória, and the army of his brother Dom Miguel, who had usurped the throne of Portugal. Though technically a victory for Pedro's forces, it gave him no lasting advantage because the enemy were not pursued and were able to return in full strength, as a result of which he was besieged in Porto for an entire year.
