After the abolition of slavery, three Constitutional amendments were passed to grant rights to freed slaves. However, the Supreme Court upheld segregation between 1873-1883, allowing separation of the races in public spaces like transportation and schools. The 1896 Plessy v. Ferguson decision cemented "separate but equal". In 1954, Brown v. Board of Education found school segregation unconstitutional, but resistance remained strong in the South. Six-year-old Ruby Bridges integrated a New Orleans school in 1960 with U.S. Marshal escorts amid white parent withdrawals and threats.
