What was one major source of conflict during the civil rights movement of the 1940s to 1950s?

One major source of conflict during the Civil Rights Movement of the 1940s to 1950s was the systemic racial segregation and discrimination entrenched in American society, particularly in the South. This was epitomized by Jim Crow laws, which enforced racial separation in public spaces, schools, and transportation. Activists faced violent opposition from white supremacist groups and law enforcement when they sought to challenge these injustices through protests, boycotts, and legal action, leading to intense confrontations and societal upheaval. The struggle for equality highlighted deep-seated racial tensions and resistance to change within American culture.
