I could add a fourth category that you could consider in your answer if you are allowed to do that.
Fourth: the leaders of the movement
In point of fact, all of them were effective. The Supreme court heard many cases on the right to vote and the right to be treated as though color were not a determining factor on voting rights. These cases helped bring about the Civil Rights act of 1964 and the Voting rights act of 1965. It put teeth into the 15th amendment, all of which you should look up.
Martin Luther King made a huge impact on Civil Rights. One of key ideas that he had was civil disobedience. Even that was strongly opposed by people like Governor George Wallace. That aside, civil disobedience was a method that peaceful people could tie into and participate in. Look up Rosa Parks as the primary example of someone very welling to stand her ground.
When you look up the Civil Rights act you will see that the Federal Government played a key role in making and enforcing key laws.
The people were ready to determine their rights as citizens. The time was right to unite the participants. Even students themselves were involved in "the people" many of whom were from many parts of the United States. You could google students civil rights movement. People your age were very influential.
Obama's visit was historic considering that he is the first American president to ever visit the country.

During his visit, Obama promised that the US would double its financial aid to the country over the course of the following three years, which was also an interesting part of the visit.
The Congressional and Presidential Reconstruction Plans had differences as regards the intensity of amnisty and leniency they managed. President Lincoln believed that he had the power and the obligation to carry on the Reconstruction. However, the Republican Members of the Congress did not agree. They said that it was the Congress the one with the power to reconstruct the south.
Hello!
The Great Depression was a period of economic slowdown in the 1930s which started with the Wall Street Crash of 1929. With no hesitations, after the Great Depression, a lot of things changed: poverty has increased, cause there wasn't money, which means that people looked for extra jobs in order to make a living and support their family. Not everything is rose colour, and there were not a lot of jobs and many citizens were unemployed. The head of the family, the father in many cases, would often leave to another town in search of work, and if he didn't succeed, families would have no money and would have to live on the street. This of course had negative effects on the family.
