Roman soldiers in 100 BC would contribute funds to pay for fallen comrades' funerals, establishing early life insurance practices. In the 1600s, Lloyd's Coffee House in London facilitated marine insurance for shipowners and merchants, eventually becoming Lloyd's of London. Major American life insurance companies like New York Life and Metlife formed in the 1800s, and the Prudential became the first to offer policies to working-class Americans in 1875. Following World War II, 72% of American adults held life insurance policies as the industry boomed, growing into an $848 billion business primarily in the United States.
