求英语作文：Say sth about the black people in the US ,their past,p

When mentioning the black people, most of us will come up with the idea of racial discrimination. As is known to us all, the black people had been treated as slaves on the American continent for centuries, until the North won the Civil War and President Lincoln announced that slavery was unconstitutional. Though the black people got the same rights as the white in law since then, they were still suffering from severe racial discrimination. However, they were brave, and never stopped fighting for equality. Nowadays, the black people are almost treated equally and accepted by the society, which is proved by President Obama, and racial discrimination is much weakened, but still exists. Looking into the future, the black people need to concentrate more on protecting their culture, if they want to be more independent and proud of being black.
