Answer:
One helpful statistic we can use is the amount of enslaved people per county, in the year 1860, just a year before the American Civil War.
Explanation:
This statistic can be used as a proxy to determine the counties were cotton had the highest production, because cotton was a cash crop grown in large plantations that were worked by enslaved African Americans.
Several counties had 80% or more slaves as percentage of the total population, meaning that they were overwhelmingly black. The majority of these counties were located in the Mississippi Delta, in the state of the same name, in the Black Belt of Alabama and Georgia, and in southern South Carolina.
Emperor Meiji finally achieved to get over the ancient and previous traditions of Shogun Lords, which lasted almost 800 years. With, the Meiji restoration, the country formerly established relations with powers in Europe, the United States, and other parts of the world. This became key "in putting Japan into the scene", in the international community. The ancient practices were not fostered anymore (based on Cultural and social distinctions ). It can be said that the nation had formerly consisted of huge differences to be considered relating what people have as an office, the status they served, etc.
So Japan finally entered the modern world, after a long series of wars that were targeted to maintaining the cultural unity and a policy of isolationism that also resulted in upgrading and incorporating changes in Japan foreign policy and structure of the military.
