Secretary of State for War in the context of "Henry Campbell-Bannerman"

Sir Winston Leonard Spencer Churchill (30 November 1874 – 24 January 1965) was a British statesman, military officer, and writer who was Prime Minister of the United Kingdom from 1940 to 1945 (during the Second World War) and again from 1951 to 1955. For some 62 of the years between 1900 and 1964, he was a Member of Parliament (MP) and represented a total of five constituencies over that time. Ideologically an adherent to economic liberalism and imperialism, he was for most of his career a member of the Conservative Party, which he led from 1940 to 1955. He was a member of the Liberal Party from 1904 to 1924.

Of mixed English and American parentage, Churchill was born in Oxfordshire into the wealthy, aristocratic Spencer family. He joined the British Army in 1895 and saw action in British India, the Mahdist War and the Second Boer War, gaining fame as a war correspondent and writing books about his campaigns. Elected a Conservative MP in 1900, he defected to the Liberals in 1904. In H. H. Asquith's Liberal government, Churchill was president of the Board of Trade and later Home Secretary, championing prison reform and workers' social security. As First Lord of the Admiralty before and during the First World War he oversaw the disastrous naval attack on the Dardanelles (a prelude to the Gallipoli campaign) and was demoted to Chancellor of the Duchy of Lancaster. He resigned in November 1915 and joined the Royal Scots Fusiliers on the Western Front for six months. In 1917, he returned to government under David Lloyd George and served successively as Minister of Munitions, Secretary of State for War, Secretary of State for Air, and Secretary of State for the Colonies, overseeing the Anglo-Irish Treaty and British foreign policy in the Middle East. After two years out of Parliament, he was Chancellor of the Exchequer in Stanley Baldwin's Conservative government, returning sterling in 1925 to the gold standard, depressing the UK economy.

The Colonial Office was a government department of the Kingdom of Great Britain and later of the United Kingdom, first created in 1768 from the Southern Department to deal with colonial affairs in North America (particularly the Thirteen Colonies, as well as the Canadian territories recently won from France), until merged into the new Home Office in 1782. In 1801, colonial affairs were transferred to the War Office in the lead up to the Napoleonic Wars, which became the War and Colonial Office to oversee and protect the colonies of the British Empire. The Colonial Office was re-created as a separate department 1854, under the colonial secretary. It was finally merged into the Commonwealth Office in 1966.

Despite its name, the Colonial Office was responsible for much, but not all, of Britain's Imperial territories; the protectorates fell under the purview of the Foreign Office, and the British Presidencies in India were ruled by the East India Company until 1858, when the India Office was formed to oversee the administration of the new Viceroyalty of India (the Crown ruled India directly through a Viceroy after the Indian Rebellion), while the role of the Colonial Office in the affairs of the Dominions was replaced by the Dominion Office in 1925.

Alfred Duff Cooper, 1st Viscount Norwich, GCMG, DSO, PC (22 February 1890 – 1 January 1954), known as Duff Cooper, was a British Conservative Party politician and diplomat who was also a military and political historian and writer.

First elected to Parliament in 1924, he lost his seat in 1929 but returned to Parliament in the 1931 Westminster St George's by-election, which was seen as a referendum on Stanley Baldwin's leadership of the Conservative Party. He later served in the Cabinet as Secretary of State for War and First Lord of the Admiralty. He resigned from the cabinet over the Munich Agreement of 1938.

The British Expeditionary Force (BEF) was the formation of the British Army on the Western Front during the First World War. In its original form it comprised six divisions, sent by Britain to France in 1914 to aid in resisting the German invasion.

Planning for a British Expeditionary Force began with the 1906–1912 Haldane Reforms of the British Army carried out by the Secretary of State for War Richard Haldane following the Second Boer War (1899–1902).

The Army Reserve is the active-duty volunteer reserve force of the British Army. It is separate from the Regular Reserve whose members are ex-Regular personnel who retain a statutory liability for service. Descended from the Territorial Force (1908 to 1921), the Army Reserve was known as the Territorial Army (TA) from 1921 to 1967 and again from 1979 to 2014, and the Territorial and Army Volunteer Reserve (TAVR) from 1967 to 1979.

The force was created in 1908 by the Secretary of State for War, Richard Haldane, when the Territorial and Reserve Forces Act 1907 combined the previously civilian-administered Volunteer Force, with the mounted Yeomanry (at the same time the Militia was renamed the Special Reserve).

The secretary at war was a political position in the English and later British government, with some responsibility over the administration and organization of the Army, but not over military policy. The Secretary at War ran the War Office. After 1794 it was occasionally a Cabinet-level position, although it was considered of subordinate rank to the secretary of state for war. The position was combined with that of secretary of state for war in 1854 and abolished in 1863.

Notable holders of the position include Henry St John, 1st Viscount Bolingbroke, Robert Walpole, Henry Pelham, Henry Fox, Henry John Temple, 3rd Viscount Palmerston, William Windham and Thomas Babington Macaulay, 1st Baron Macaulay.

Lord Kitchener Wants You is a 1914 advertisement by Alfred Leete which was developed into a recruitment poster. It depicted Lord Kitchener, the British Secretary of State for War, above the words "WANTS YOU". Kitchener, wearing the cap of a British field marshal, stares and points at the viewer calling them to enlist in the British Army against the Central Powers. The image is considered one of the most iconic and enduring images of World War I. A hugely influential image and slogan, it has inspired imitations in other countries.
