Reliastar Life Insurance Company was a life insurance company that was acquired by Voya Financial in 2000. It was originally founded in 1887 as Northwestern National Life Insurance Company and later changed its name to Reliastar Life Insurance Company. The company offered a range of life insurance products, including term life insurance, whole life insurance, and universal life insurance. Reliastar also provided annuities and retirement planning services. After being acquired by Voya Financial, the Reliastar brand was eventually phased out, and its products and services were integrated into Voya's offerings. As a result, Reliastar Life Insurance Company no longer operates as an independent entity, but its legacy continues through Voya Financial's insurance and financial services. Overall, Reliastar Life Insurance Company had a long history in the life insurance industry and played a significant role in providing financial protection and security to its policyholders.
