Answer:
The invasion of Poland marked the start of World War 2. Britain and France were not convinced that it was a defensive war and it all began world war 2.

New tactics and technology were tested in Poland and those same tactics will later be even more developed against France.

Answer:
The Black Codes, sometimes called Black Laws, were laws governing the conduct of African Americans (free blacks). The best known of them were passed in 1865 and 1866 by Southern states, after the American Civil War, in order to restrict African Americans' freedom, and to compel them to work for low wages. However, Black Codes existed before the Civil War, and many Northern states had them. In 1832, "in most of the United States, there is a distinction in respect to political privileges, between free white persons and free coloured persons of African blood; and in no part of the country do the latter, in point of fact, participate equally with the whites, in the exercise of civil and political rights."
