The Hanover Insurance Group, Inc., based in Worcester, MA, is one of the oldest continuous businesses in the United States, still operating within its original industry. It was the original name of a property-liability insurance firm born in 1852, and it remained a publicly-traded company under that name until the early 1990s, when it changed its name to Allmerica Property & Casualty Companies.

In 1996, it spun off Allmerica Financial Corporation as a property and casualty insurance and financial services holding company, which then bought out the original firm, and grew to become one of the 500 largest publicly-traded companies of the United States. In 2005, Allmerica Financial Corporation reverted its name back to Hanover.  In 2009, the company acquired the commercial business from OneBeacon Insurance Group, which enabled them to expand into the western United States. The company offers personal and business insurance and is rated “A” (Excellent) by A.M. Best.
