Book Description
A beautiful commemorative edition of Dr. Martin Luther King's essay "Letter from Birmingham Jail," part of Dr. King's archives published exclusively by HarperCollins. With an afterword by Reginald Dwayne Betts On April 16, 1923, Dr. Martin Luther King Jr., responded to an open letter written and published by eight white clergyman admonishing the civil rights demonstrations happening in Birmingham, Alabama. Dr. King drafted his seminal response on scraps of paper smuggled into jail. King criticizes his detractors for caring more about order than justice, defends nonviolent protests, and argues for the moral responsibility to obey just laws while disobeying unjust ones. "Letter from Birmingham Jail" proclaims a message - confronting any injustice is an acceptable and righteous reason for civil disobedience. This beautifully designed edition presents Dr. King's speech in its entirety, paying tribute to this extraordinary leader and his immeasurable contribution, and inspiring a new generation of activists dedicated to carrying on the fight for justice and equality.
