Why did some northerners object to abolitionism?

Some Northerners objected to abolitionism due to economic interests, as many were reliant on the labor of free laborers and feared that emancipation would disrupt the labor market. Others held racist beliefs, fearing that freed Black individuals would migrate north and compete for jobs or threaten social order. Additionally, some Northerners believed in a gradual approach to emancipation or felt that immediate abolition would lead to increased tensions and conflict between the North and South.
