With a POD from 1800 onwards, use any means possible to form an early Spanish Republic than IOTL of the late 1800's. Bonus points if it survives to the 20th century.
If the PoD and the Republic must be after 1800, then I'd go for a vastly different 1848 across the continent, spilling into Spain, too, which was less affected IOTL.
If the Republic may be earlier, I remember a timeline from last year about a successful Comuneros Revolt and a republican-confederal Spain from the 16th century on. Intriguing idea IMO and quite plausible, too.
I think the best PoD for such a scenario would be Napoleon being defeated, but somehow not killed, at the Battle of Marengo. Which is hard, i'm afraid, considering that France would lose the strategic initiative from that point on in.In 1800, Spain breaks the peace of Basel and war resumes with France. This backfires as French revolutionary forces advance on Madrid and Charles IV flees. The Hispanic Republic is then created.

Reviving this thread; would this work? Weren't the people of Spain loyal to the Spanish King and thus would resist French occupation?
There would surely be Spanish royalists who would resist. This régime would however have the benefit of being an elected government composed of Spanish citizens (pro-French in sentiment, but Spanish nonetheless), instead of an installed monarch like Joseph.
If this occurs, how will the Spanish New World react? I assume the Peace of Amiens might be delayed, at most by 2 years I think.
