Why did Bob Dylan write a song about Emmett Till?

Bob Dylan wrote "The Death of Emmett Till" to address the brutal murder of the African American teenager in 1955 and to highlight the racial injustice and violence prevalent in American society at the time. The song serves as a poignant commentary on systemic racism and the indifference of society toward such atrocities. By using Till's story, Dylan aimed to raise awareness and provoke thought about civil rights issues, making it a powerful protest song that resonated with the burgeoning Civil Rights Movement.
