Answer: The fifteenth United states amendment had a good impact on the African American population. This 15th Agreement granted African American men the freedom to vote by stating that "the right of people of the United States to vote shall not be restricted or abridged by the United States or any State for reasons of race, colour, or prior condition of servitude."
At a time when trade and transport were made primarily by water, and bearing in mind that European powers needed to have free access to the rich colonies, and only by sea could they communicate with America and the colonies, the ocean and the seas were the higways of the past. Therefore, access and control of the sea routes, was the only way to have control over the colonies, their riches; and become the dominant power in the world. In addition, the wars between France and Great Britain were not only for trade or wealth, but for power itself, to decide who would dominate the seas.
As far as I know I'm pretty sure they weren't free due to the laws around the time period
