"Letter from Birmingham Jail" is a pivotal piece of Black history written by Dr. Martin Luther King Jr. in 1963. The letter was a response to a group of white clergymen who criticized King and his nonviolent protest tactics in the Birmingham campaign aimed at ending segregation in Alabama.

In the letter, King defends his approach to nonviolent resistance and civil disobedience, highlighting the moral imperative to fight against injustice. He argues that waiting for a more convenient time to address civil rights issues is a form of complacency and that immediate action is necessary to achieve justice.

"Letter from Birmingham Jail" became a significant document in the civil rights movement, emphasizing the importance of nonviolent protest and the power of moral indignation in the face of systemic racism. It continues to be studied and cited as a foundational text in the struggle for racial equality and social justice.
