I'm looking at how to bring about an earlier Mexican War of Independence, so far the three main scenarios that there seem to be are
- The rumours that Bernardo Galvez was considering following the US and declare a republic along with his being killed for it are true and he avoids being poisoned
- The Conspiracy of the Machetes isn't betrayed and succeeds in starting a revolution, covertly aided by Britain as part of the on-going Anglo-Spanish War
- After the invasion of Spain and abdication of the King the coup against Agustín de Iturbide fails to capture him, a Cry of Dolores or similar occurs and things play out from there
