While Emmett's body floats the foam of a Jim Crow southern sea.
Under Jim Crow, African Americans were relegated to the status of second class citizens. Jim Crow represented the legitimization of anti-Black racism. This included segregation in public places, education and more; blacks were viewed as inferior.
The Jim Crow Southern Sea Bob Dylan is saying is actually the Tallahatchie River. The same one Emmett Till was dumped in.
