Both Europe and Japan had a "cast system" you could say, where peasants worked the land that the nobles owned. (The Japanese had their own terms for the people, I just can't remember them.) During this time, Europe had knights and these Knights had a code called Chivalry. Over in Japan, there were Samurai with a very similar code which was called Bushido. Hope this helps.
In general, history is the recorded story of the interaction between "ideas" "people" and "patterns", since it is the way in which people act and make decisions that influences their collective history.
American ships became targets of attack by 1917 because Americans continued to trade with the warring nations.
At that time, the american vowed that we adopt a non-interventionist policy during the war time. But when we continue to trade with warring nations, other nations viewed it as we supplying materials and supplies to one of the nations that involved in the war. This is why american ships became targets of attack.
