Explanation:

Matthew C. Perry was a commodore of the United States Navy who played a pivotal role in the opening up of Japan to the West. Perry engaged in this mission in 1852. His goal was to convince, or if necessary, force, the Japanese ports to open to American trade. This was motivated by several reasons, such as competition with Great Britain and France for influence in Asia, the doctrine of Manifest Destiny, imperialist interests and the desire to increase American wealth. Although Japan was initially reluctant, they eventually complied after several subtle threats of force.
