b. race riots in New York and Detroit 

The Detroit, New York, and Texas riots are the significant protests at that time. 1943 was carried out in the region of Detroit of the United States, from the night of June Twenty to the early morning of June Twenty-two.

It happened in a time of climactic community which increases the cultural tensions incorporated with the army buildup of World War II, as Detroit's automotive manufacturing was transformed into the conflict.
