  Britain retains sovereignty over 14 territories outside the British Isles. In 1983, the British Nationality Act 1981 renamed the existing Crown Colonies as "British Dependent Territories", and in 2002 they were renamed the British Overseas Territories. Most former British colonies and protectorates are members of the Commonwealth of Nations, a voluntary association of equal members, comprising a population of around 2.2 billion people. The United Kingdom and 14 other countries, all collectively known as the Commonwealth realms, voluntarily continue to share the same person— King Charles III —as their respective head of state. These 15 nations are distinct and equal legal entities: the United Kingdom, Australia, Canada, New Zealand, Antigua and Barbuda, The Bahamas, Belize, Grenada, Jamaica, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands and Tuvalu.
  
  Decades, and in some cases centuries, of British rule and emigration have left their mark on the independent nations that rose from the British Empire. The empire established the use of the English language in regions around the world. Today it is the primary language of up to 460 million people and is spoken by about 1.5 billion as a first, second or foreign language. Individual and team sports developed in Britain, particularly football, cricket, lawn tennis, and golf were exported. British missionaries who travelled around the globe often in advance of soldiers and civil servants spread Protestantism (including Anglicanism) to all continents. The British Empire provided refuge for religiously persecuted continental Europeans for hundreds of years.
  
  Political boundaries drawn by the British did not always reflect homogeneous ethnicities or religions, contributing to conflicts in formerly colonised areas. The British Empire was responsible for large migrations of peoples. Millions left the British Isles, with the founding settler colonist populations of the United States, Canada, Australia and New Zealand coming mainly from Britain and Ireland. Millions of people moved between British colonies, with large numbers of South Asian people emigrating to other parts of the empire, such as Malaysia and Fiji, and Overseas Chinese people to Malaysia, Singapore and the Caribbean. The demographics of the United Kingdom changed after the Second World War owing to immigration to Britain from its former colonies.
  
  In the 19th century, innovation in Britain led to revolutionary changes in manufacturing, the development of factory systems, and the growth of transportation by railway and steamship. British colonial architecture, such as in churches, railway stations and government buildings, can be seen in many cities that were once part of the British Empire. The British choice of system of measurement, the imperial system, continues to be used in some countries in various ways. The convention of driving on the left-hand side of the road has been retained in much of the former empire.
  
  The Westminster system of parliamentary democracy has served as the template for the governments of many former colonies, and English common law for legal systems. International commercial contracts are often based on English common law. The British Judicial Committee of the Privy Council still serves as the highest court of appeal for twelve former colonies.
  
  Historians' approaches to understanding the British Empire are diverse and evolving. Two key sites of debate over recent decades have been the impact of post-colonial studies, which seek to critically re-evaluate the history of imperialism, and the continued relevance of historians Ronald Robinson and John Gallagher, whose work greatly influenced imperial historiography during the 1950s and 1960s. In addition, differing assessments of the empire's legacy remain relevant to debates over recent history and politics, such as the Anglo-American invasions of Iraq and Afghanistan, as well as Britain's role and identity in the contemporary world.
  
  Historians such as Caroline Elkins have argued against perceptions of the British Empire as a primarily liberalising and modernising enterprise, criticising its widespread use of violence and emergency laws to maintain power. Common criticisms of the empire include the use of detention camps in its colonies, massacres of indigenous peoples, and famine-response policies. Some scholars, including Amartya Sen, assert that British policies worsened the famines in India that killed millions during British rule. Conversely, historians such as Niall Ferguson say that the economic and institutional development the British Empire brought resulted in a net benefit to its colonies. Other historians treat its legacy as varied and ambiguous. Public attitudes towards the empire within 21st-century Britain have been broadly positive although sentiment towards the Commonwealth has been one of apathy and decline.
