The Meiji Restoration of Japan

Before Japan began modernizing their country, they didn't allow other countries to negotiate with them. In 1853, four American steam ships came to Japan by U.S. Commodore Matthew Perry, and he wanted the Japanese to open their doors to other countries. The Japanese were scared because of the ships being powered by steam, and they all carry cannons and rifles. Either they do it or Perry will have to force them. But then the Japanese became impressed of how the ships don't need any sails.
