Answer:
An exaggerated devotion to the interests of a region over those of a country as a whole
Step-by-step explanation:
Sectionalism is defined as an exaggerated devotion to the interests of a region over those of a country as a whole, meaning in my own words that it is the favoring of a region over the whole area or country. Sectionalism is the expression of loyalty or support for a particular region of one's country, rather than to the country as a whole. In contrast to simple feelings of local pride, sectionalism arises from deeper cultural, economic, or political differences and can lead to violent civil strife, including insurrection.
Bonus: The most obvious example of sectionalism in the U.S is the contest between the North and the South in the Civil War. But to focus on this ignores “the various geographic provinces of the United States and the regions within them, and exhibiting itself in economic, political, and cultural fields”.
