The Perry Expedition was a diplomatic and military undertaking to Japan during its Bakumatsu period. The Expedition involved two separate trips of steamships of the United States Navy, which took place during 1852-1854. The goals of the expedition included exploration, surveying, the establishment of diplomatic relations, and the "opening" of Japan to trade with the United States. The Perry Expedition had a colossal influence on 19th century Japan, leading to interaction with, and influence by, the outside world, the collapse of the Tokugawa shogunate and the Meiji Restoration. In the Western world, the opening of Japan to trade led to a period of Japonism in decorative and fine arts and culture.
