Letter from Birmingham Jail
open letter written by Martin Luther King, Jr

The "Letter from Birmingham Jail", also known as the "Letter from Birmingham City Jail" and "The Negro Is Your Brother", is an open letter written on April 16, 1963, by Martin Luther King Jr. It says that people have a moral responsibility to break unjust laws and to take direct action rather than waiting potentially forever for justice to come through the courts. Responding to being referred to as an "outsider", King writes: "Injustice anywhere is a threat to justice everywhere."
The letter, written in response to "A Call for Unity" during the 1963 Birmingham campaign, was widely published, and became an important text for the civil rights movement in the United States. The letter has been described as "one of the most important historical documents penned by a modern political prisoner", and is considered a classic document of civil disobedience.
Background
Birmingham, Alabama, was known for its intense segregation and attempts by some residents to combat said racism during this time period. For example, students at Miles College boycotted local downtown stores for eight weeks, which resulted in a decrease in sales by 40% and two stores desegregating their water fountains. The Alabama Christian Movement for Human Rights (ACMHR) had met with the Senior Citizens Committee (SCC) following this protest in hopes to find a way to prevent larger forms of retaliation against segregation. The SCC, a white civic organization, had agreed during this meeting to remove all "Whites Only" signs from downtown department stores, however failed to carry this promise through. The citizens of Birmingham's efforts in desegregation caught King's attention, especially with their previous attempts resulting in failure or broken promises. Their desire to be active in fighting against racism is what made King certain that this was where he needed to begin his work.

Why this record matters
“Letter from Birmingham Jail” is worth following because a concise public description often conceals a longer documentary argument. Here, Letter, Birmingham and Jail provides the most credible route into that argument.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q1609768. The first chronological checks are 1963.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
