sit-ins cultural definition

A form of nonviolent protest, employed during the 1960s in the civil rights movement and later in the movement against the Vietnam War. In a sit-in, demonstrators occupy a place open to the public, such as a racially segregated (see segregation) lunch counter or bus station, and then refuse to leave. Sit-ins were designed to provoke arrest and thereby gain attention for the demonstrators' cause.

• The civil rights leader Martin Luther King, Jr., defended such tactics as sit-ins in his “Letter from Birmingham Jail.”
