Final answer:
The American Civil War was the conflict over the use of slave labor in agriculture, deeply rooted in the economic disparities between the North and the South, and was propelled towards emancipation particularly after the Emancipation Proclamation.
Step-by-step explanation:
The conflict fought over the use of slave labor in agriculture was the American Civil War. This war was deeply rooted in the division over slavery, as the Southern economy was heavily reliant on agricultural production that depended on slave labor. The North, on the other hand, did not have an economic structure that profited from slavery, leading to ideological and economic disparities that fueled the war. The African American Civil Rights Movement and historical figures, such as Frederick Douglass, highlighted the importance of African American participation in the war to end slavery and fight for freedom, especially after Lincoln's Emancipation Proclamation, which gave the Civil War a new cause — the abolishment of slavery.
