Final answer:
The 1866 Mechanics' Institute riot resulted in significant racial violence, with 119 blacks and 17 supporters injured, and 37 blacks and 3 white allies killed. The event further exacerbated racial tensions and the post-Civil War struggle for African American rights, while showcasing the federal government's inadequate response to violence against blacks.
Step-by-step explanation:
As a result of the 1866 Mechanics' Institute riot, a horrific display of racial violence unfolded in New Orleans. The incident began when a peaceful procession of blacks was fired upon; the sad aftermath saw 119 blacks and seventeen of their supporters injured, with thirty-seven black individuals and three white allies killed. This violent outbreak fueled the already tense atmosphere and displayed the stark racial divisions in the post-Civil War South.
Additionally, the Mechanics' Institute riot and other similar events exacerbated racial tensions and highlighted the struggles faced by African Americans, including their systemic mistreatment and the challenges of reconstruction. These occurrences showed that racial discrimination persisted even after the end of slavery and emphasized the need for stronger protections and advancements in civil rights for African Americans.
Furthermore, the strife during this period also indicated that federal authorities frequently turned a blind eye to the violence against blacks, which perpetuated a cycle of injustice and unrest.
