From the 16 Century slave traders took african men, woman and children in America to work on the large plantations.

In 1865 slavery was abolished in all part of U.S.A. but black people and white people were not equal, black people couldn' t vote, they couldn't sit on the same buses or in the restaurants as american citizens or go to the same schools.

This changed with Martin Luther King, a Baptist Minister from Alabama and he became the leader of one of the largest protest movements of 20 century.

In 1955 a worker called Rosa Parks was arrested because she refused to give up her seat reseved for white people on a bus, this story caused a massive public protest: King boycotted the bus company and for many weeks black workers stopped going on the buses. This boycott lasted util the buses agreed to end segregation.

Martin Luther King' s movement continued and in 1963 he led 250.000 people in a march to Whashington D.C. he gave one of the most famous speeches of 20 Century. That speech was called "I have a dream" because he repeted this sentence many times.

In his public appearance King spoke about his dream for equality between black and white citizens in America:

"I have a dream that my four little children will one day live in a Nation where they will not be judged by the colour of their skyn, but by the content of their character"..."I have a dream that one day the sons of former slaves and the sons of former slave owners will be able to sit together at the table of brotherblood". 

King went in prison several times for his belief, but he continued to work for equality. Some people heated his work and in 1968, he was assasined. But before this happened he saw the abolition of racial discrimination laws in 1964-1965 and in 1964 he won the Nobel Prize for Peace.

Martin Luther King was one of most important in American History.
