With one of the oldest and largest ethnic manuscript collections in the United States, the Norwegian-American Historical Association (NAHA) is a leader in the field of ethnic migration studies. The NAHA archival collection includes letters, ledgers, books, periodicals, photographs, diaries, and audio and video recordings. The materials bring life to thousands of individuals, organizations, and businesses comprising the Norwegian diaspora in North America since migration began in the early 19th century.

Since its founding in 1925, NAHA has been located on the campus of St. Olaf College. Although both institutions are independent entities, they maintain close cooperation on common causes. The NAHA archives are located in the special collections area of Rolvaag Memorial Library. Read more about NAHA on our historical timeline.

NAHA maintains close ties to NAHA-Norge, known in Norway as Det norske-amerikanske historielaget i Norge. As an independent, non-profit organization, NAHA-Norge aims to promote scholarly interests in Norwegian-American studies in Norway, as well as to encourage Norwegian contributions to this field of study.
