<h3>Hello!</h3><h3>First, I would review what the freedmen and the black codes are.</h3>
Freedmen - The freedmen are the group of slaves that were released from their previous masters, the freed slaves.
Black Codes - The black codes were a set of rules that applied to black people, passed back in the slave era. They included rules that restricted the ownership of property, relationships with white women, etc.
<h3>These therefore impacted the lives of the freedmen, as it restricted their actions.</h3>
The rules caused them to have to watch what they were doing in public spaces, or else there would be bad consequences (If you want to further look into the bad consequences, the story of Emmett Till is an example)
<h3>Hope this helped!</h3>
I'm not too sure what you are asking, however if you are looking for what ended the Spanish War, Island of Puerto, it would be the Treaty of Paris of 1898.
The Spanish War was fought between America and Spain, and took place in Cuba, Puerto Rico, Guam, and the Philippines.
The twenty-fourth amendment which was proposed by Congress on 27th August 1962 and ratified by the most states on 23rd January 1964 was very significant act for the African-Americans. It gave them right to vote by eliminating poll taxes and thus gave them political rights and say in the formation of government. The amendment also established equality and ended discrimination with African-Americans.
