to the establishment of the insurance market Lloyd's of London and several related shipping and insurance businesses. The participating members of the insurance arrangement eventually formed a committee and moved to the Royal Exchange on Cornhill as the Society of Lloyd's. The establishment of insurance companies, a developing infrastructure of specialists (such as shipbrokers, admiralty lawyers, bankers, surveyors, loss adjusters, general average adjusters, et al.), and the growth of the British Empire gave English law a prominence in this area which it largely maintains and forms the basis of almost all modern practice. Lord Mansfield, Lord Chief Justice in the mid-eighteenth century, began the merging of law merchant and common law principles. The growth of the London insurance market led to the standardization of policies and judicial precedent further developed marine insurance law. In 1906 the Marine Insurance Act codified the previous common law; it is both an extremely thorough and concise piece of work. Although the title of the Act refers to marine insurance, the general principles have been applied to all non-life insurance. In the 19th century, Lloyd's and the Institute of London Underwriters (a grouping of London company insurers) developed between them standardized clauses for the use of marine insurance, and these have been maintained since. These are known as the Institute Clauses because the Institute covered the cost of their publication. Out of marine insurance, grew non-marine insurance and reinsurance. Marine insurance traditionally formed the majority of business underwritten at Lloyd's. Nowadays, Marine insurance is often grouped with Aviation and Transit (cargo) risks, and in this form is known by the acronym 'MAT'. It is common for marine insurance agencies to compete with the offerings provided by local insurers. These specialist agencies often fill market gaps by providing cover for hard-to-place or obscure marine insurance risks that would otherwise be difficult or impossible to find insurance cover for. These agencies can become quite large and eventually become market makers. They operate best when their day-to-day management is independent of the insurers who provide them with the capital to underwrite risks on their behalf. As of 2020, the Nordic region was the largest provider of marine hull insurance at 14% of the world market, China second at 12.4% and Lloyd's of London third at 8.6%, according to the International Union of Marine Insurance.
