Founding Story
Unum traces its roots back to 1848 when the Union Mutual Life Insurance Company was founded in Portland, Maine. Initially operating as a traditional life insurer, the company struggled through the late 19th and early 20th centuries. The critical turning point occurred when the company aggressively pivoted toward the highly specialized disability insurance market. Through a series of massive mergers, notably the 1999 merger with Provident Companies, Unum Group was formed, establishing the undisputed global leader in group disability and workplace financial protection.
