Step-by-step explanation:
Medgar Evers was working with the National Association for the Advancement of Colored People (NAACP) in Mississippi to fight segregation and promote civil rights. Evers was named the NAACP's first field secretary in Mississippi, a significant role that had him traveling throughout the state. He was deeply involved in efforts to encourage African Americans to register to vote and actively participate in the civil rights movement. Despite the threats he faced, including a violent opposition that ultimately led to his assassination, Evers remained steadfast in his commitment to nonviolence and justice.
In his role with the NAACP, Evers also played a critical part in investigating and bringing attention to cases of racial injustice, such as the Emmitt Till murder. His work to secure an order for the admission of James Meredith to the University of Mississippi was a landmark event in the fight against segregation in higher education. After his tragic death, his wife Myrlie Evers continued to run the local NAACP office and became a national leader in the organization.
