British Dominions in the context of "Allied Powers of World War I"

The Allies or the Entente (UK: /ɒ̃ˈtɒ̃t/, US: /ɒnˈtɒnt/ on-TONT) was an international military coalition of countries led by the French Republic, the United Kingdom, the Russian Empire, the United States, the Kingdom of Italy, and the Empire of Japan against the Central Powers of the German Empire, Austria-Hungary, the Ottoman Empire, and the Kingdom of Bulgaria in World War I (1914–1918).

By the end of the first decade of the 20th century, the major European powers were divided between the Triple Entente and the Triple Alliance. The Triple Entente was made up of the United Kingdom, France, and Russia. The Triple Alliance was originally composed of Germany, Austria–Hungary, and Italy, but Italy remained neutral in 1914. As the war progressed, each coalition added new members. Japan joined the Entente in 1914 and, despite proclaiming its neutrality at the beginning of the war, Italy also joined the Entente in 1915. The term "Allies" became more widely used than "Entente", although the United Kingdom, France, Russia, and Italy were also referred to as the Quadruple Entente and, together with Japan, as the Quintuple Entente. The five British Dominions (Australia, Canada, New Zealand, Newfoundland, and the Union of South Africa) all fought alongside the British. The colonies of Allied countries, such as the American Philippines, Belgian Congo, British India, French Algeria, and Japanese Korea, were also used as a source of manpower by the colonial powers.

George V (George Frederick Ernest Albert; 3 June 1865 – 20 January 1936) was King of the United Kingdom and the British Dominions, and Emperor of India, from 6 May 1910 until his death in 1936.

George was born during the reign of his paternal grandmother, Queen Victoria, as the second son of the Prince and Princess of Wales (later King Edward VII and Queen Alexandra). He was third in the line of succession to the British throne behind his father, and his elder brother, Prince Albert Victor. From 1877 to 1892, George served in the Royal Navy, until his elder brother's unexpected death in January 1892 put him directly in line for the throne. The next year George married his brother's former fiancée, Princess Victoria Mary of Teck, and they had six children. When Queen Victoria died in 1901, George's father ascended the throne as Edward VII, and George was created Prince of Wales. He became king-emperor on his father's death in 1910.

Alexandra of Denmark (Alexandra Caroline Marie Charlotte Louise Julia; 1 December 1844 – 20 November 1925) was Queen of the United Kingdom and the British Dominions, and Empress of India, from 22 January 1901 to 6 May 1910 as the wife of King Edward VII.

Alexandra's family had been relatively obscure until 1852, when her father, Prince Christian of Schleswig-Holstein-Sonderburg-Glücksburg, was chosen (with the consent of the major European powers) to succeed his second cousin Frederick VII as King of Denmark. At the age of 16, she was chosen as the future wife of Albert Edward, Prince of Wales, the son and heir apparent of Queen Victoria. The couple married 18 months later in 1863, the year in which her father became king of Denmark as Christian IX and her brother William was appointed king of Greece as George I.

The convoy—a group of merchantmen or troopships traveling together with a naval escort—was revived during World War I (1914–18), after having been discarded at the start of the Age of Steam. Although convoys were used by the Royal Navy in 1914 to escort troopships from the Dominions, and in 1915 by both it and the French Navy to cover their own troop movements for overseas service, they were not systematically employed by any belligerent navy until 1916. The Royal Navy was the major user and developer of the modern convoy system, and regular transoceanic convoying began in June 1917 with the assistance of the US and other Allied navies. They made heavy use of aircraft for escorts, especially in coastal waters, an obvious departure from the convoy practices of the Age of Sail.

As historian Paul E. Fontenoy put it, "[t]he convoy system defeated the German submarine campaign." From June 1917 on, the Germans were unable to meet their set objective of sinking 600,000 long tons (610,000 t) of enemy shipping per month. In 1918, they were rarely able to sink more than 300,000 long tons (300,000 t). Between May 1917 and the end of the war on 11 November 1918, only 154 of 16,539 vessels convoyed across the Atlantic had been sunk, of which 16 were lost through the natural perils of sea travel and a further 36 because they were stragglers.

Mary of Teck (Victoria Mary Augusta Louise Olga Pauline Claudine Agnes; 26 May 1867 – 24 March 1953) was Queen of the United Kingdom and the British Dominions, and Empress of India, from 6 May 1910 until 20 January 1936 as the wife of King George V.

Born and raised in London, Mary was the daughter of Francis, Duke of Teck, a German nobleman, and Princess Mary Adelaide of Cambridge, a granddaughter of King George III. She was informally known as "May", after the month of her birth. At the age of 24, she was betrothed to her second cousin once removed Prince Albert Victor, Duke of Clarence and Avondale, who was second in line to the throne. Six weeks after the announcement of the engagement, he died unexpectedly during a pandemic. The following year, she became engaged to Albert Victor's only surviving brother, George, who subsequently became king. Before her husband's accession, she was successively Duchess of York, Duchess of Cornwall, and Princess of Wales.
