Final answer:
The New York Draft Riots erupted on July 13, 1863, over Union draft and racial tensions.
It involved widespread violence, targeting of African Americans and their sympathizers, and significant property damage before federal troops restored order.
Step-by-step explanation:
The city in question that saw a trial turn into a massive race riot, ending in three days of fighting, was New York City.
This violence erupted over the Union draft and racial tensions on July 13, 1863, just two days after the first draft lottery.
Known as the New York Draft Riots, it was marked by its particularly violent character and its targeting of African American individuals and sympathizers, including the destruction of property and heinous acts of lynching.
The riot was fueled by resentment among working-class New Yorkers over the Civil War draft, particularly due to a provision that allowed wealthier men to buy their way out of conscription, which contributed to the class-based animosities that played out during the riots. The chaos was quelled after four days with the intervention of federal troops.
