'We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed' Martin Luther King

In an era where the liberties we often take for granted are under threat, Letters To Change the World is a collection of inspiring letters offering reminders from history that standing up for and voicing our personal and political beliefs is not merely a crucial right but a duty if we want to change the world.

Edited by Travis Elborough, the collection includes George Orwell's warning on totalitarianism, Martin Luther King's 'Letter from a Birmingham Jail', Albert Camus on the reasons to fight a war, Bertrand Russell on peace, Emmeline Pankhurst rallying her suffragettes, Nelson Mandela's letter to his children from prison and Time's Up on the abuse of power.

Travis Elborough, described as 'one of Britain's finest pop culture historians' by the Guardian, has been a freelance writer, author, broadcaster and cultural commentator for nearly two decades. His books include The Bus We Loved, London Bridge in America, and A Walk in the Park. Our History of the 20th Century: As Told in Diaries, Journals and Letters was published in 2017.
