What were some of the causes for the downfall of the south in 1865?

The downfall of the South in 1865 was primarily driven by military defeats, notably the surrender of key Confederate armies and the relentless Union campaigns, such as Sherman's March to the Sea. Economic devastation due to the destruction of infrastructure, loss of slave labor, and blockades that crippled trade also played significant roles. Additionally, internal divisions and dwindling resources weakened the Confederate resolve and ability to sustain the war effort. Ultimately, these factors culminated in the collapse of the Confederacy and its surrender.
