Martin Luther King DayToday is a national holiday in the United States to celebrate the life of Martin Luther King, Jr.
It's easy to forget the kind of hatred and stupidity that King was fighting against, but a good place to start is with the history of the Jim Crow laws in the United States. The Wikipedia entry for Jim Crow laws also has detailed information. And the Wikipedia entry for King is here.
Also, here's a link to a 2006 post when Eli asked me about Martin Luther King for the first time. It's still one of my favorite posts.
