Napoleon Bonaparte 's invasion of Iberia, forcing the abdication of Charles IV and replacing him with Bonaparte 's brother Joseph, produced unforeseen changes in Spain and its overseas empire.

Royal government disappeared and local strongmen emerged in the Spanish American republics in the wake of these wars.
