We shall love our people.

I have a dream.

One day, this nation will rise up, live out the true meaning of its dream.

Because we intend to fire our people up so much, until if they can't have their equal share in the house, they'll burn it down.

This city right side is a challenge to all of us.

To go to work in our communities and our states, in our homes and in our hearts, to eliminate the last vestiges of injustice.

Welcome to this new History Extra podcast series, where we'll be charting key moments in the transformative history of the US Civil Rights Movement.

This fight for equality dominated mid-20th century America and its consequences have reverberated around the world as well as down the decades.

I'm Rianne Davis, section editor for BBC History magazine, and over the next six episodes, I'll be speaking to leading historians to explore some of the crucial moments that defined the fight for civil rights.

As there's so much history to this history, each episode our experts will recount one significant story from the movement and explore its place in the wider struggle for civil rights.

We'll be discussing some of the men and women who have been enshrined as heroes of the movement, such as Martin Luther King Jr. and Rosa Parks,

as well as shining a light on some of the thousands of forgotten grassroots activists who helped pave the way for change, through marching in protests, taking part in boycotts, or even sacrificing their jobs, their freedom, and in some cases their lives in pursuit of racial equality.

Our first episode sees us travel back to 1955 as Mississippi Bakes in the summer sun. Emmett Till, a black 14-year-old boy, has travelled down to the deep south from his native Chicago to enjoy the long summer days with his extended family.

However, his vacation quickly descends into a nightmare.

Devery Anderson, an author who's written a biography of Till, shares the teenager's tragic story.

Please be aware that this episode contains graphic details that some listeners may find disturbing.

Emmett Till was a 14-year-old African-American youth from Chicago who, in the summer of 1955, took a train to Mississippi with his great uncle and a cousin to spend the last two weeks of summer vacation in Mississippi.

While he was there, he broke one of the taboos that he did not understand but which black people in Mississippi understood well, and that is a black man talking in any way familiar with a white woman.

And while in money Mississippi, Emmett Till went into a little grocery store after picking cotton for the day with his cousins.

They went into this store to buy some refreshments. While in there, he said something to the woman that upset her.

This was Caroline Bryant, a 21-year-old who was born and raised in the south and who worked in Bryant's grocery and meat market in money Mississippi.

She followed him out of the store. When she did, he turned to her and waved and said, buy, which you didn't do if you were black.
