Answer:

The double-V campaign was: b) the effort to end discimination against african americans while fighting fascism.

Explanation:

During world war II in 1942, the Double V movement first showed up. It is led by African Americans to fight against racism in the US and in the European and Pacific theaters. It demands for equal rights in exchange of the sacrifice that they made in the war.

The reason why this campaign was started is due to the Jim Crow law in which there is segregated public facilities such as schools, parks, businesses, etc and this worked as a fuel for the moment and later this movement became the frontier for the civil rights movement.

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
