Edward VIII (Edward Albert Christian George Andrew Patrick David; 23 June 1894 – 28 May 1972) was King of the United Kingdom and the Dominions of the British Empire, and Emperor of India, from 20 January 1936 until his abdication on 11 December the same year.
The 1926 Imperial Conference was the seventh Imperial Conference bringing together the prime ministers of the dominions of the British Empire.
 It was held in London from 19 October to 22 November 1926.
 The conference was notable for producing the Balfour Declaration, which established the principle that the dominions are all equal in status, and "autonomous communities within the British Empire" not subordinate to the United Kingdom.
 The term "Commonwealth" was officially adopted to describe the community.
Dominions were semi-independent polities under the British Crown, constituting the British Empire, beginning with Canadian Confederation in 1867.
 They included Canada, Australia, New Zealand, Newfoundland, South Africa, and the Irish Free State, and then from the late 1940s also India, Pakistan, and Ceylon (now Sri Lanka).
 The Balfour Declaration of 1926 recognised the Dominions as "autonomous Communities within the British Empire", and the 1931 Statute of Westminster granted them full legislative independence.
The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states.
 It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries.
 At its height, it was the largest empire in history and, for over a century, was the foremost global power.
 By 1913, the British Empire held sway over 412 million people, % of the world population at the time, and by 1920, it covered 35500000 km2 , % of the Earth's total land area.
 As a result, its political, legal, linguistic and cultural legacy is widespread.
 At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories.
The Royal Northern Hospital was a general hospital on Holloway Road, London N7, near Tollington Way.
 It had inpatient, outpatient, accident and emergency facilities and was also a centre for postgraduate education.
 Originally located at King's Cross, it began as an independent and voluntary hospital.
 The Great Northern Hospital moved to Holloway Road in 1888 and received a royal charter on amalgamation with the Royal Chest Hospital in 1921.
 The casualty department was built using public subscription.
 The foundations to the new casualty department was laid by Lady Patricia Ramsay in July 1923, and the new building was opened by the Prince of Wales on 27 November 1923.
The Burma Campaign in the South-East Asian theatre of World War II was fought in the British colony of Burma primarily between the forces of the British Empire and China, with support from the United States, against the invading forces of Imperial Japan, Thailand, and the Indian National Army.
 British Empire forces peaked at around 1,000,000 land and air forces, and were drawn primarily from British India, with British Army forces (equivalent to 8 regular infantry divisions and 6 tank regiments), 100,000 East and West African colonial troops, and smaller numbers of land and air forces from several other Dominions and Colonies.
 The Burmese Independence Army (known to the legitimate Burmese government and the Allies as the "Burmese Traitor Army" - BTA) was trained by the Japanese and spearheaded the initial attacks against British Empire forces.
The Statute of Westminster 1931 is an Act of the Parliament of the United Kingdom and modified versions of it are now domestic law within Australia and Canada; it has been repealed in New Zealand and implicitly in former Dominions that are no longer Commonwealth realms.
 Passed on 11 December 1931, the act, either immediately or upon ratification, effectively both established the legislative independence of the self-governing Dominions of the British Empire from the United Kingdom and bound them all to seek each other's approval for changes to monarchical titles and the common line of succession.
 It thus became a statutory embodiment of the principles of equality and common allegiance to the Crown set out in the Balfour Declaration of 1926.
 It was a crucial step in the development of the Dominions as separate states.
The Succession to the Throne Act (1 Geo.
 VI, c.16) is the act of the Canadian parliament that ratified the Cabinet's consent to His Majesty's Declaration of Abdication Act 1936, an act of the United Kingdom parliament that allowed Edward VIII to abdicate as king of Canada, the United Kingdom, and the other Dominions and pass the throne to George VI.
 However, it was the Canadian government's request and consent, and not the Succession to the Throne Act, that gave the British Act of Parliament effect in and made it part of the law of Canada, as per section 4 of the Statute of Westminster 1931, which allowed the British parliament to legislate for the Dominions only with their agreement.
Lindsay Steven Carstairs FRCR (1919-1998) was a Scottish radiologist.
 Born in Glasgow, he served in the Royal Army Medical Corps during the Second World War and was present at the D-Day landings.
 He was associated with the Royal Northern Hospital for most of his career where he became a consultant radiologist.
 He was a fellow of the British Medical Association and, in retirement, curator of the museum of the Royal College of Radiologists.
The 1930 Imperial Conference was the seventh Imperial Conference bringing together the Prime Ministers of the dominions of the British Empire.
 It was held in London.
 The conference was notable for producing the Statute of Westminster, which established legislative equality for the self-governing Dominions of the British Empire with the United Kingdom, thereby marking the effective legislative independence of these countries, either immediately or upon ratification.
 Economic relations within the British Empire was also a key topic with proposals for a system of Imperial preference - empire-wide trade barriers against foreign (i.e. non-empire) goods.
 These proposals were further discussed at the British Empire Economic Conference in 1932.
