Southern cities maintain segregated public facilities like a Greensboro, North Carolina lunch counter, where four black college students stage the first sit-in. The non-violent sit-in movement spreads to 69 cities across the South with black communities organizing economic boycotts and sympathetic Northerners picketing stores. In Nashville, protesters are arrested and attacked but do not retaliate. The bombing of the house of Z. Alexander Looby, a lawyer working with the activists, led to thousands marching to City Hall.
