What are two categories of nonviolent protest used in the African American Civil Rights Movement?

The modern civil rights movement grew out of a long history of social protest. In the South, any protest risked violent retaliation. Even so, between 1900 and 1950, community leaders in many Southern cities protested segregation. The National Association for the Advancement of Colored People (NAACP), the leading civil rights organization of this era, battled racism by lobbying for federal anti-lynching legislation and challenging segregation laws in court.
