"Kavanagh" is the story of a country romance. Besides a character named Kavanagh, among its characters is a school teacher named Mr. Churchill, who has always planned to write a romance, but whose procrastination never allows him to start, until late in life he resigns himself to his "destiny."
Longfellow used the novel to argue against the view, in the book propounded by a character based on Cornelius Mathews, that American literature must be entirely devoid of European influences and be exclusively national. Instead, Longfellow felt that American literature could and should be universalist, with its unique North American influences. He saw the use of European models not as imitation but as a "continuation" that Americans could be proud of.
