Was the "Civil War" about slavery, or was secession about slavery? Or, can it be either as convenience allows?
Why did the North introduce slavery to the South? Was it a good idea, or something we just don't talk about...questions that we ignore?
If the war was about slavery, why did the North maintain their slaves after those in the South were free?
The war was about slavery...right?
Why the continued deption of labeling, such as "Civil War" & "United States"?
Please ignore any questions that you may feel uncomfortable with.
The confederates fired on the US flag, and suffered the consequences.
The south seceded because it felt that the institution of slavery was at stake. Free states were gaining ground in the congress. Lincoln carried the free states ... it was the end of power for slave states. They bolted immediately. That is the history. Deny it if you will. But those are the facts.
Not every slave state chose to secede. The free states were coming into majority power and slavery was near its end. The actual effect of the Emancipation Proclamation of 1863 was that by 1865 there were no slaves anywhere in the US. By Dec of 1865, the states had ratified the 13th Amendment.
Before his assasination in early 1865, Lincoln had personally pressed the House of Representatives to get the 2/3rds majority to approve the 13th amendment. The senate had previously gone for it massively. It took less than a year for the states to forever abolish slavery.
Slavery had remained legal in the US due to the early influence of southern voting power. As soon as they lost power, slavery was abolished. There was no huge appetite for slavery in the north, contrary to your implication. An institution maintained for 300 years by southern pressure ended in the blink of an eye -- just as the south lost voting majority.
