Answer:
1. Black Ships
2. Treaty of Kanagawa
3. Shimoda and Hakodate
4. Matthew C. Perry
Step-by-step explanation:
1. Commodore Matthew Perry's vessels were called the Black Ships, because of the black hulls and black smoke produced by the skip.
2. The treaty of Kanagawa (mainly called the Convention of Kanagawa) was the first treaty between Japan and the United States. Allowing commerce between Japan and the US was beneficial in the integration of Japan into current areas of technology [along with economics] and growing foreign relations.
(The treaty of Versailles was about Germany giving up power, it forced Germany to take the blame for World War I and limitations on the German military. )
3. The first two ports of foreign trade opened [by Japan] to the US were Shimoda and Hakodate--in the Convention of Kanagawa (I point this out because it was a previous answer, many key factors of trade between Japan and the US were impacted by the Convention of Kanagawa).
4. Matthew C Perry commanded ships in multiple wars, but his leadership in the opening of Japan to the United States / to the West [with the Convention of Kanagawa!!] was a crucial role.
Hope this helps!! :)
