Emmett Till, a 14-year-old African American from Chicago, visited his relatives in Money, Mississippi, for the summer. He allegedly had an interaction with a white woman, Carolyn Bryant, in a small grocery store that violated the norms of Mississippi culture, and Bryant's husband Roy and his half-brother J. W. Milam brutally murdered young Emmett Till. They beat and mutilated him before shooting him in the head and sinking his body in the Tallahatchie River. Three days later, Till's body was discovered and retrieved from the river. After Emmett's mother, Mamie Till, came to identify the remains of her son, she decided she wanted to "let the people see what I have seen". Till's mother then had his body taken back to Chicago where she had it displayed in an open casket during the funeral services where many thousands of visitors arrived to show their respects. A later publication of an image at the funeral in Jet is credited as a crucial moment in the civil rights era for displaying in vivid detail the violent racism that was being directed at black people in America. In a column for The Atlantic, Vann R. Newkirk wrote: "The trial of his killers became a pageant illuminating the tyranny of white supremacy".The state of Mississippi tried two defendants, but they were speedily acquitted by an all-white jury.

"Emmett's murder," historian Tim Tyson writes, "would never have become a watershed historical moment without Mamie finding the strength to make her private grief a public matter." The visceral response to his mother's decision to have an open-casket funeral mobilized the black community throughout the U.S. The murder and resulting trial ended up markedly impacting the views of several young black activists. Joyce Ladner referred to such activists as the "Emmett Till generation." One hundred days after Emmett Till's murder, Rosa Parks refused to give up her seat on the bus in Montgomery, Alabama. Parks later informed Till's mother that her decision to stay in her seat was guided by the image she still vividly recalled of Till's brutalized remains.
