Not very much.
Most Northerners were not abolitionists. They were ready to tolerate slavery in its traditional heartlands, and enjoy the cotton revenues that went with it.
The reason why most of them wanted to forbid more slave-states was to preseve the Northern majority in Congress and continue to protect manufacturing industry via the high taxes on imported goods that the South mostly needed.
However, if the Abolitionists were not very numerous, many of them were influential and impossible to ignore in Congress. The various controversies of the 1850's (Fugitive Slave Law, Publication of 'Uncle Tom's Cabin', the Kansas vote etc.) set up an increasingly fierce debate that could only end in war.
An abolitionist was important in the civil war because abolitionists wanted to abolish or get rid of slavery. And for a lot of people the war was about slavery.
John Brown, Harriet Tubman and Fredrick Douglass were all pre-Civil War abolitionists

John Brown
An Abolitionist supported the abolition or end of slavery during the US Civil War.
While Abraham Lincoln was opposed to the expansion of slavery, he did not consider himself a fervent abolitionist. He viewed the Civil War as a struggle to preserve the Union rather than a religious war. Lincoln's primary goal was to keep the United States together and end slavery as a means to achieve that end.
