black or white ?

Between the 15th and 19th centuries, black people were victims of the legal slave trade, they were enslaved. Slavery was abolished in 1777.

The descendants of these surviving African slaves are the Afro-Americans.

Afro-Americans are victims of strong discrimination by white Americans. They are separated from society: schools and toilets are reserved for them, for example.

December 1,1955, at Montgomery Rosa Louise McCauley Parks, known as Rosa Parks, refuses to give up her seat to a white man on a bus and she is stopped by the police.

A 26-year-old black boy, Martin Luther King, then launched a 380-day protest and boycott campaign against the bus company. On November 13,1956, the United States Supreme Court overturned segregationist laws on buses, declaring them unconstitutional.

Martin Luther King thus becomes the leader in civil rights for blacks.
On August 28,1963, in Washington, his speech “I have a dream” is listened to by the whole world and remains symbolic.
