In 1834, Harvard called him to the chair of Modern Languages.

He again made a trip to Europe for further study.

Longfellow was connected with Harvard for nineteen years, resigning his position in 1854 to devote his whole time to literature.
His two principal prose works are "Outre Mer" and "Hyperion." The latter was followed by a volume of poems entitled "Voices of the Night." "Ballads and Other Poems" appeared in 1841, and showed much more talent.

"Evangeline" was written in 1847; "Hiawatha" in 1855, and the "Courtship of Miles Standish" in 1857.

"Evangeline" and "Hiawatha" are considered the best of his longer poems.
