Answer:
The Union (also known as the North) won the American Civil War. The main reasons for the Union's victory were its superior resources (including manpower), transportation, and industrial capacity, as well as the effective leadership of President Abraham Lincoln and the military strategies of General Ulysses S. Grant.
Moreover, the Union’s decision to abolish slavery and the support of abolitionists in the North were essential factors in the Union’s success. The Confederacy (or the South) had fewer resources and was essentially an agrarian-based economy, which made it harder to sustain a long war. The Confederacy was also divided by internal conflicts and lacked a strong central government.
