Final answer:
Jim Crow laws were abolished with the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965 following a long civil rights movement.
Step-by-step explanation:
Jim Crow laws, a set of discriminatory laws primarily in effect in the Southern United States, dictated racial segregation from their deep-rooted establishment following the end of the Civil War until the mid-20th century. The Civil Rights Act of 1964, alongside the Voting Rights Act of 1965, were key legislations that ultimately abolished these laws. The process of dismantling Jim Crow began decades before they were fully overturned, including significant Supreme Court decisions and the ongoing struggle of the Civil Rights Movement which used nonviolent protest to challenge segregation and disenfranchisement.
