The time of segregation was not a pretty one in American history. The Remember Segregation site does an excellent job of portraying that.
Starting with actual “white” and “colored” entrances to the site, you are exposed to stirring images from the age of segregation, both uplifting and disturbing ones. While much of the site is merely a tribute to Martin Luther King, there are also great soundclips of King’s speeches, a timeline of civil rights events, and the text of some of King’s speeches.
