Laura Ingalls Wilder did not publicly identify herself as a libertarian, but the term was not in yet common usage during her lifetime. Additionally, information on her political beliefs is not widely available.
Laura’s daughter, Rose Wilder Lane, was long associated with the libertarian movement in the United States though. Lane was associated with the libertarian movement and was considered one of the leading figures of the “Old Right,” a conservative movement in the United States that emerged in the 1930s and 1940s and advocated for limited government, low taxes, and free market economics.
She was particularly known for her work as a writer and editor for the libertarian magazine “The Freeman” and her book “The Discovery of Freedom,” which was published in 1943 and is considered a libertarian classic.
