During the war he was initially a royalist, and played a role in the defeat of the leading rebel José María Morelos, while fighting at the head of the Fieles de Potosi Batallion.

[1] Under the First Mexican Republic, he was governor and commandant general of the State of Puebla in 1824, where he was accused of not being harsh enough during political insurrections, and of not having provided protection to several foreigners who were robbed.

[4] Yorkino revolts against the results broke out at Veracruz in September 1828, and at Mexico City, and they were significant enough to cause Gomez Pedraza to question the loyalty of the army.

Gomez Pedraza vacillated as the revolutionaries made more gains, and he eventually decided to concede, resigning the ministry and leaving the country for France after which congress recognized the events and declared Guerrero president and Anastasio Bustamante vice president[5] Two years later Gomez Pedraza returned from Bordeaux in October 1830, but the government of Anastasio Bustamante did not allow him to enter the country and he disembarked and headed for the United States, eventually settling in Pennsylvania.

After the overthrow of Bustamante in 1832 through the Plan of Veracruz, the revolutionists resolved on inviting Gomez Pedraza back into the country to serve out the remaining months of the term he was first elected to in 1828.

[6] He met with the leading rebel Santa Anna who assured Gomez Pedraza that this revolution had a popular character which the previous ones had lacked, that among his supporters were prominent men of all views, and free from partisan spirit.

Later as part of the senate he helped pursue President José Joaquín de Herrera’s aim of seeking a diplomatic solution to the Texas problem, hoping to recognize its independence, while gaining concessions that would allow Mexico an honorable end to the decade long conflict, but this was interrupted by a coup led by Mariano Paredes who was part of a faction of hardliners who preferred war.

[17] At the end of the war, as the Mexican government was based in Queretaro, Gomez Pedraza took part in the confidential consultory commissions, established by president Pedro Maria Anaya.

The government of President José Joaquín de Herrera commissioned him to conclude a treaty with Robert P. Letcher regarding communications across the Isthmus of Tehuantepec.
