Answer:
to give them ownership of all spices he found
Step-by-step explanation:
King Ferdinand and Queen Isabella supported Colombus hoping to find a route into the Far East, they ambitioned the spieces found in the India
The route was to come to Asia by sailing west.
Columbus set with the promise to give them ownership over all the spiced found across so he sailed in 1492 believing a western route would lead him to Asia.
Of course, the Spanish kings ambitioned spices and profited from the trade.
Columbus found the spices of America: flavors like chili pepper , cayenne and allongspice were first made known to the Spanish.
The silk was also highly valued as a item for trade.
The Spanish kings supported him because they believed the spices would come faster in this route.
A letter records a text by Colombus to King Ferdinand and Queen Isabella, suggesting that Spanish should come to the lands he came in contact that same year and advising that colonies and exploration in the New continent will lead Spain to become rich.
