Could someone explain to me what the nullification crisis is, I look online and find it hard to understand so could you try to explain it as best you can?

The gist of this is that South Carolina was trying to remove the federal income tax from their state, meaning that their state wasn't going to force anyone to pay their federal taxes. The reasoning behind this was that the South Carolina government deemed the laws requiring citizens to pay federal income tax unconstitutional. The Federal Government obviously disagreed with this, so there was a lot of arguing over whether or not South Carolina's citizens had to pay their federal income taxes.

In the end, both sides got what they wanted, as South Carolina got less tariffs from the federal government, and the federal government got the citizens of South Carolina to pay their federal income taxes.
