It happened after ww1 and was influenced those from the war. The war had people see more violently and thus this art appears more of less like dada are but more violent.

Not sure it did limit freedoms of Loyalists post Revolutionary War, however during the war I imagine ones that lived in Revolutionary controlled regions were restricted in movment and expression. Most Native Americans however, sided with the British because of the proclamation of 1763. This was an outcome of the French and Indian War and prevented colonists from expanding west of the Appalachians to prevent more conflict with natives. Colonists did not like this, they wanted to expand as far west as they wanted.
Okay, so, Lincoln had to wait for a Union victory. Antietam Was the victory he needed.
The Emancipation Proclamation changed the course of the war. It went from defeating the Rebels of the South to freeing the slaves. In every place that the Union army could take, the Slaves were all freed. This was a huge boost to the troops. They were now fighting to free people. Freeing all the slaves would have done nothing to keep the men fighting. the fight needed a better cause. Is there a better cause than Freedom? Fighting to unite the Country and fighting for freedom are far different things. Even today fighting for freedom is still top on everyones list.
I hope this helped you. :)
