Explanation:
The opposition of the segregation argued that the act of segregation is a direct violation of the constitution. This amendment acknowledged black people/former slaves as citizens.

While I'm not exactly sure which countries you've studies, I can provide you with two main differences between a dictatorship and a democracy.
In a democracy people get to vote where each person gives a vote which is worth something as he/she is a part of nation that decided on their new representative. In dictatorship this is absent. People are not allowed to vote on anything.
Another difference is that in a democracy you have an active government with a elected president. In a dictatorship you have a self-appointed leader of a country which doesn't allow people to tell him how he should run his country.
