I believe the correct answer was 1823. Hope this was helpful!
The tensions over the slavery caused conflict in America primarily because of the different political views on the matter, as well as the economy.
The North wanted to modernize, and to follow the example of the European countries that abolished the slavery, thus they wanted the slaves to be freed, and to be equal citizens in the society. Also, the North was industrialized, so they were really not dependent on slaves to keep their economy going.
The South wanted things to remain the same. They did not wanted the slavery to be abolished, but instead to remain as it is. The economy of the south was largely based on the plantations with different types of crops. Big portion of the work done on the plantations was done by the slaves, so if they were freed, that would mean that the plantations would either be left without enough laborers, or the former slaves would have demanded wages that would lower the profit of the plantation owners.
This disagreements eventually led to a bloody conflict, which ended up with a win for the North.
It is first important to understand that not all Republicans rejected a peace settlement with the Confederates during or after the Civil War, but it was a smaller group within the party that totally and completely refused and demanded a full surrender without conditions to the South. This group was called the Radical Republicans and they began around 1854 and went until after the Reconstruction of 1877. They were the ones who were responsible for the establishment of the Fourteenth Ammendment and they radically opposed any negotiations with the South on the basis of their being totally against segregation and slavery. Some other factions within the Republican party, including Lincoln, were more moderate and were willing to give in to some of the demands from the Confederates, especially ont he issue of slaves.
The reason for these radical Republicans not wanting to negotiate with the Southern Confederates, was that they refused to allow slavery to continue. They were pushing for all slaves in the U.S to be freed, for segregation to be prohibited, for rights for black people to be established in the United States and even went as far as pushing for civil rights, including suffrage, for African Americans. But the South, of course, refused these terms. This is why neither Radical Republicans, nor Confederate members would have been able to settle anything in a negotiation. There was no common ground for the toughest issue of all; slavery.
