Answer :

African-Americans challenged segregation in several different ways including:

1) Nonviolent forms of protest- During the 1950's and 1960's, African-Americans took place in several different forms of nonviolent protest. This included sit-ins, marches, and boycotts. The goal was to raise attention to the fact that black Americans were treated like second class citizens.

2) Forming organizations- After World War II, groups like the Student Nonviolent Coordinating Committee (SNCC) began to form as a means to help African-Americans gain equal rights in American society. These groups organized protests and helped politicians get elected who were willing to fight for civil rights.

Answer:

African Americans were being treated as inferior citizens even after World War II.  The  African American veterans who risked their lives overseas were rightfully unwilling to accept discrimination at home. The initiative to achieve racial equality became what now is called the Civil Rights Movement. The citizens went to the streets and made several peaceful protests, including parading, boycotts, and even went to court to assure they would be treated as equals (including legally)
