Answer:
To find an easie route to Asia
Step-by-step explanation:
Because the Turks had closed the Asian route,Christopher Columbus instead thought to reduce the distance of the trip by navigating in the opposite direction.

That is why he sailed west in the hope of reaching east faster than the Portuguese who had to circumnavigate the entire African coast
