The Perry Expedition arrives in Edo Bay with a treaty requesting trade.

The Perry Expedition was a diplomatic and military expedition in two separate voyages to the Tokugawa shogunate (徳川幕府) by warships of the United States Navy. The goals of this expedition included exploration, surveying, and the establishment of diplomatic relations and negotiation of trade agreements with the various nations in the region. Opening contact with the government of Japan was considered a top priority of the expedition, and was one of the key reasons for its inception.

Edo, also romanized as Jedo, Yedo or Yeddo, is the former name of Tokyo.
