what caused spain to lose its influence in the new world
Spanish Empire 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. The outbreak of the Spanish American wars of independence was a result of Napoleon's destabilizing actions in Spain and led to the fragmentation of the former viceroyalties into independent nation-states. Royal government disappeared and local strongmen emerged in the Spanish American republics in the wake of these wars.[18]
History of Mexico Colonial Mexico was part of the Spanish Empire and administered by the Viceroyalty of New Spain. The Spanish crown claimed all of the Western Hemisphere west of the line established between Spain and Portugal by the Treaty of Tordesillas. This included all of North America and South America, except for Brazil. The viceroyalty of New Spain had jurisdiction over Spain's northern empire in the Americas. When Spain established a colony in the Philippines in the late sixteenth century, the Viceroyalty of New Spain had jurisdiction over it, since there was more direct contact between the two than the Philippines with Spain.
