'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.
