Final answer:
The correct option is 2) The Great Depression.
The end of Prohibition and the start of the Great Depression brought an end to the Harlem Renaissance. As a result, the illegal alcohol in Harlem's clubs wasn't needed, and economic hardships led to the decline of the vibrant cultural movement.
Step-by-step explanation:
One event that signaled the beginning of the end for the Harlem Renaissance and the vibrant club scene in Harlem was the end of the era known as Prohibition. This period, which lasted from 1920 to 1933, saw the ban of the manufacture, sale, and transportation of intoxicating liquors.
With the end of Prohibition, the illegal alcohol that was once plentiful in the clubs was no longer necessary, leading to changes in patronage and the social scene. Further, the Great Depression, which began with the stock market crash of 1929, led to widespread economic hardship, affecting the prosperity of Harlem and its residents.
Consequently, many influential individuals from Harlem relocated in search of employment, and after the Harlem Race Riot of 1935, the Renaissance that had celebrated African American culture and arts faded away.
