Which explorer was associated with an attempt to find a direct route to Asia in the Northern Hemisphere in 1497?

John Cabot, an Italian explorer sailing under the English flag, is well known for his 1497 voyage that aimed to establish a direct route to Asia by navigating through the Northern Hemisphere. His expedition is significant as it was one of the earliest European explorations of North America. Cabot believed that by sailing westward from Europe, he could reach Asia more quickly than by going around Africa. This voyage ultimately led him to the coast of what is now Canada, marking an important moment in the history of exploration and the beginning of the English presence in North America.

Other figures mentioned, such as Sir Walter Raleigh, Henry Hudson, and Sir Francis Drake, were involved in exploration but focused on different objectives and periods. Raleigh is known for attempts to establish colonies in Virginia; Hudson was famous for his explorations in the early 17th century that led to the discovery of parts of North America; and Drake was known for his circumnavigation of the globe and privateering against Spanish ships. Cabot's specific goal to find a route to Asia in 1497 distinguishes him as the correct answer.
