How did the monroe doctrine contribute to sectionalism in the us?

Explanation:

James Monroe led to sectionalism by passing the Compromise of 1820, also known as the Missouri Compromise. This compromise stated that for any state that has slavery, it must have a sister state in which slaves are free. This idea was controversial and led to a deeper feud between the North and the South. They had already been disagreeing in the Senate, which was also feeling the affects of sectionalism. The Senate had divided into North, South, and West sections. The North and South always disagreed, therefore causing the West to make all the decisions.

Mainly, the Missouri Compromise added to growing sectionalism in our country under James Monroe.
