Why did Spain succeed to conquering so much of the Americas?

Spain succeeded in conquering a large part of the Americas due to a combination of factors, including:

Advanced military technology: The Spanish were equipped with advanced military technology, such as firearms, cannons, and steel swords, which gave them a significant advantage over the indigenous peoples of the Americas.

Disease: European diseases, such as smallpox, measles, and influenza, decimated the indigenous populations, weakening their resistance to Spanish conquest.

Political disunity: The indigenous peoples of the Americas were often divided into small, warring tribes, which made it difficult for them to mount a unified resistance against the Spanish.

Spanish alliances: The Spanish were able to form alliances with some indigenous groups, who were willing to help them in their conquest of other tribes.

Superior military strategy: The Spanish were able to use their military technology and alliances to their advantage, developing strategies that allowed them to defeat larger indigenous forces.

Economic resources: Spain had access to a large amount of economic resources, which allowed it to support its long-term conquest of the Americas.
