The fate of black people from 1933 to 1945 in Nazi Germany and in German-occupied territories ranged from isolation to persecution, sterilization, medical experimentation, incarceration, brutality, and murder. However, there was no systematic program for their elimination as there was for Jews and other groups.
After World War I, the Allies stripped Germany of its African colonies. The German military stationed in Africa (Schutztruppen), as well as missionaries, colonial bureaucrats, and settlers, returned to Germany and took with them their racist attitudes. Separation of whites and blacks was mandated by the Reichstag (German parliament), which enacted a law against mixed marriages in the African colonies.
Over a period of several centuries, Jews established communities outside of Jerusalem as far east as Central Asia and as far West as Spain. is TRUE
The Articles of Confederation were essentially an early version of the US Constitution that were created as a governing agreement among the 13 original colonies/states to fight the Revolution and establish some limited federal power.

The Columbian Exchange had positive and negative consequences.
Some of the positive consequences were the introduction of different nutrients and food supplies into the Old World, such as corn or potatoes. This improved the diet of most Europeans, leading to a population growth in the next generations.
However, Europe benefited more than the Americas, for some of the negative consequences about the Columbian Exchange were the introduction of diseases into the continent and the slavery of African populations into the Americas.
