The 3 major Rivers are the Seine River, Rhone River and the Loire River.
The development that probably hurt it is the reduction of open range herding. In history, people could just let their cattle roam freely and find food since the plains were huge and nobody lived in them. Nowadays, this can be problematic because there are more and more people and settlements and roads with cars so free range herding has been drastically reduced which cost the herders a lot.
The 15th Amendment to the Constitution granted African American men the right to vote by declaring that the "right of citizens of the United States to vote shall not be denied or abridged by the United States or by any state on account of race, color, or previous condition of servitude." Although ratified on February 3, 1870, the promise of the 15th Amendment would not be fully realized for almost a century. Through the use of poll taxes, literacy tests and other means, Southern states were able to effectively disenfranchise African Americans. It would take the passage of the Voting Rights Act of 1965 before the majority of African Americans in the South were registered to vote.
I hope this helps! Ask me if you need anything else! :))
