Final answer:
The anti-lynching bill of 1922 aimed to make lynching a federal crime but failed in the U.S. Senate due to Southern senators' threat of filibuster, despite efforts by civil rights activists and organizations.
Step-by-step explanation:
The legislation in question that aimed to make lynching a federal crime was introduced to the U.S. Congress in 1922. Despite the efforts of civil rights organizations like the NAACP and leaders such as Ida Wells, who put forward a steadfast campaign against lynching, the anti-lynching bill was unsuccessful in the Senate due to the threat of a filibuster from Southern senators. These events occurred during a time when racism and racial violence were prevalent in the United States, particularly in the South, where the vast majority of lynchings took place. White southern politicians fiercely resisted any federal intrusion into what they saw as state matters, even in the face of humanitarian crises. Subsequent attempts at passing federal anti-lynching legislation were made, but none succeeded in the face of united opposition from white Southern Democrats.
