Insurance originated thousands of years ago when groups would pool resources to protect merchants transporting goods from losses. The first formal insurance company was formed in London in 1688 and focused on protecting sea voyages. Modern insurance developed further after the Great Fire of London in 1666 when societies were formed for people to pool money to cover losses. The first American insurance company was established in Charleston, South Carolina in 1735 and the industry has grown significantly over the centuries to become a trillion dollar business employing millions of people.
