2 Dec 2015 — An unassuming middle-aged woman staged a simple protest that had dramatic and historic consequences.
On 1 December 1955, Rosa Parks refused to move further back from her seat on a bus in Montgomery, Alabama. Her defiance became a symbol of the civil-rights movement; local activists organized a boycott of the bus system that lasted 381 days. Props to the PBS NewsHour for reminding me.
The (in)famous bus is on display at the Henry Ford Museum.
