In a ruthless political move, Atahualpa directed the gold-hungry Spanish to loot two of the empire's most sacred temples. Both were located in regions loyal to his civil war rival, Huascar, effectively using the invaders as a tool to punish his internal enemies.

Francisco Pizarro's initial success was built on a partnership with Diego de Almagro. By negotiating a vastly superior royal deal for himself, he sowed the seeds of a bitter rivalry. This internal feud between the co-founders would fester and ultimately prove fatal to their entire enterprise and their lives.

Facing mutiny, Francisco Pizarro drew a line in the sand, offering a stark choice between returning to poverty or pursuing riches through extreme hardship. This dramatic act served as a powerful filter, weeding out the uncommitted and forging an intensely loyal core group—the "Famous 13"—who would stick with him through anything.

Once easily accessible gold was gone, the Spanish conquest of Peru transitioned from looting to institutionalized exploitation. Pizarro began granting `encomiendas`—huge tracts of land with thousands of indigenous laborers. This shifted the economic model from a short-term gold heist to a long-term colonial system based on forced tribute.

Conquistador expeditions were entrepreneurial ventures, not state campaigns. Leaders like Pizarro formed partnerships, raised private funds, and invested in high-risk "island hopping" operations hoping for massive returns. This model privatized both the risk of failure and the rewards of success, mirroring modern venture capital.

The conquest of the Americas was a highly legalistic endeavor. Conquistadors sought official royal charters, essentially operating under a franchise model. This legal cover was crucial not for legitimacy with the natives, but to protect their claims from rival Spanish adventurers, blending brute force with bureaucratic procedure.

The Spanish conquest of the Incas succeeded largely because they inserted themselves into an existing civil war. By siding with the southern Inca faction against the northern one, they gained crucial local allies, transforming the conflict from a foreign invasion into a complex, multi-sided war they could manipulate.

The arrival of a new Spanish faction under Diego Almagro created a power struggle. Almagro's men, who had no relationship with Atahualpa and wanted to seize Cusco's gold for themselves, successfully pressured a reluctant Pizarro to kill the emperor to advance their own agenda.

By sending gold and sensationalized, best-selling accounts back to Spain, the initial conquistadors created a "gold rush" narrative. This attracted waves of new adventurers to Peru, ensuring a continuous supply of manpower that made the empire's eventual fall inevitable, regardless of early setbacks.
