AUL can trace its history back to the formation of a life insurance program by the Knights of Pythias in 1877. That insurance arm, which became United Mutual Life Insurance Company, later merged with American Central Life Insurance Company to form AUL. In 2000, AUL was the founding member of American United Mutual Insurance Holding Company and its stock holding company, OneAmerica Financial Partners, Inc.
