On 28 August 1963 the March on Washington for Jobs and Freedom filled the Lincoln Memorial grounds.
Context
A speech is not a statute. It is a public rights claim in the capital the same year as Birmingham. Jobs were in the title; later memory often drops them.
Martin Luther King Jr.’s documented role is bounded by other offices and collaborators named in the sources below.
A. Philip Randolph and Bayard Rustin built the march. Rustin was kept off some letterheads. Kennedy’s White House bargained the tone. Shared.
Why it matters
Randolph and Rustin remain principals.
