In the the Spanish Empire generally, the royal state and the state church were tightly coupled. One hierarchy supposedly answered to the Viceroy and then the King; the other to the Archbishop and the Pope. Certain racial and educational qualifications were expected of high officials in both. This question is about individual mobility between the two power centers.
At the very end of the imperial period, some creole priests did get into politics: Hidalgo and many others pursued military careers, and Fernández San Vicente was Iturbide's commissioner to the Californias. Creoles were definitely ascendant. I hope to learn whether these specific priests were innovators or part of a persistent trend of political involvement.
Did other New Spanish priests have political careers before Mexico's war of independence (pictured)?
