Unum Group began as Union Mutual Life Insurance Company, chartered in Maine on July 17, 1848, to provide accessible life insurance to workers during the Industrial Revolution. Founder Elisha B. Pratt and 11 incorporators built a mutual company model emphasizing policyholder ownership and conservative investing.

Founding Story

Elisha B. Pratt founded Union Mutual in 1848 in Maine; the first policy was a $5,000 life contract written for Pratt himself. The firm operated from Boston initially, later moving headquarters to Portland and focusing on individual life insurance amid limited actuarial data.

In 1939 the company entered the non-cancellable disability market and by 1940 had a dedicated disability department that became the primary growth engine as employers adopted disability coverage.

International expansion, 1970s

International expansion began in the 1970s with entry into the United Kingdom in 1970; the company later became the leading provider of group income protection in that market.

Demutualization and IPO, 1986

In 1986 Union Mutual demutualized and launched an IPO as Unum Corporation, unlocking capital for acquisitions and marking a pivotal point in the History of Unum.

Acquisition of Paul Revere, 1997

Unum acquired Paul Revere Corporation for $2.8 billion in 1997, expanding individual and group benefits capabilities and reflecting a major event in Unum Group company history.

Merger with Provident, 1999

These milestones—headquarters relocation in 1881, entry into non-cancellable disability insurance in 1939–1940, UK expansion in 1970, demutualization and IPO in 1986, the $2.8 billion Paul Revere acquisition in 1997, and the $5.2 billion Provident merger in 1999—form a clear Unum Group timeline and explain how the company evolved from a generalist life insurer into a global income-protection specialist; see Competitors Landscape of Unum Group for related context.
