H. Why did the cultures of ancient Mesopotamia, Egypt, and India NOT develop in isolation

Explanation:

These cultures have learned a lot from being with other people that are not of their culture. This basically means that, for example, when the wheel was invented in ancient Mesopotamia, other cultures found it useful and adapted the idea to fit their own specific needs. These cultures you listed could not have been as powerful if they stayed to themselves in isolation. But because they did venture out and fight and learn, they have become what they are.

Before the Civil War, citizenship was often limited to Native Americans of one-half or less Indian blood. In the Reconstruction period, progressive Republicans in Congress sought to accelerate the granting of citizenship to friendly tribes, though state support for these measures was often limited. In 1888, most Native American women married to U.S. citizens were conferred with citizenship, and in 1919 Native American veterans of World War I were offered citizenship. In 1924, the Indian Citizenship Act, an all-inclusive act, was passed by Congress. The privileges of citizenship, however, were largely governed by state law, and the right to vote was often denied to Native Americans in the early 20th century
