What age are you?
As for your question, how much time have you got?
We could go through the background; from slavery, Black Civil Rights (MLK, Malcolm X, Rosa), black militancy (which bred the Black Panthers), the Black Panthers (with Huey P. Newton, Bobby Seale, Bobby Hutton at the beginning to it's continueing legacy today with Tupac Shakur, Mutulu Shakur, Kwame Ture, Assatta Shakur etc.), to the FBI & CIA's involvement (Cointepro & the like), the disintegration of the movement & it's splitting into the Crips &, later, the Bloods.
Then we could get into what they've been doing since their inception to now & the part they have played in street culture in America & Hip Hop culture. Famous events, members etc.
Or you could use Google & read up by yourself....
