Events on August 9 in history

Edward VII and Alexandra of Denmark are crowned King and Queen of the United Kingdom of Great Britain and Ireland.

The United Kingdom of Great Britain and Ireland was the British state as it existed between 1801 and 1922, when it included all of Ireland. It was established by the Acts of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland into a unified state. The establishment of the Irish Free State in 1922 led to the remainder later being renamed the United Kingdom of Great Britain and Northern Ireland in 1927.

The United Kingdom, having financed the European coalition that defeated France during the Napoleonic Wars, developed a large Royal Navy that enabled the British Empire to become the foremost world power for the next century. For nearly a century from the final defeat of Napoleon following the Battle of Waterloo to the outbreak of World War I, Britain was almost continuously at peace with Great Powers with the most notable exception being the Crimean War with the Russian Empire in which actual hostilities were relatively limited. However, the United Kingdom did engage in extensive offensive military operations in Africa and Asia, such as the Opium Wars with the Qing Dynasty, to extend its overseas territorial holdings and influence. Beginning in earnest in the second half of the nineteenth century, the Imperial government granted increasing levels of autonomy to locally-elected governments in colonies where white settlers had become demographically and/or politically dominant, with this process eventually resulting in Canada, Australia, New Zealand, Newfoundland and South Africa becoming self-governing dominions. Although these dominions remained part of the British Empire, in practice dominion governments were permitted to largely manage their own internal affairs without interference from London, which was primarily responsible only for foreign policy.

Rapid industrialisation that began in the decades prior to the state's formation continued up until the mid-19th century. The Great Irish Famine, exacerbated by government inaction in the mid-19th century, led to demographic collapse in much of Ireland and increased calls for Irish land reform. The 19th century was an era of rapid economic modernisation and growth of industry, trade and finance, in which Britain largely dominated the world economy. Outward migration was heavy to the principal British overseas possessions and to the United States. The British Empire was expanded into most parts of Africa and much of South Asia. The Colonial Office and India Office ruled through a small number of administrators who managed the units of the empire locally, while democratic institutions began to develop. British India, by far the most important overseas possession, saw a short-lived revolt in 1857. In overseas policy, the central policy was free trade, which enabled British and Irish financiers and merchants to operate successfully in many otherwise independent countries, as in South America.

The British remained non-aligned until the early 20th century when the growing naval power of the German Empire increasingly came to be seen as an existential threat to the British Empire. In response, London began to cooperate with Japan, France and Russia, and moved closer to the United States. Although not formally allied with any of these powers, by 1914 British policy had all but committed to declaring war on Germany if the latter attacked France. This was realized in August 1914 when Germany invaded France via Belgium, whose neutrality had been guaranteed by London. The ensuing First World War eventually pitted the Allied and Associated Powers including the British Empire, France, Russia, Italy and the U.S. against the Central Powers of Germany, Austria-Hungary and the Ottoman Empire. The deadliest conflict in human history up to that point, the war ended in an Allied victory in November 1918 but inflicted a massive cost to British manpower, materiel and treasure.

Growing desire for Irish self-governance led to the Irish War of Independence almost immediately after the conclusion of World War I, which resulted in British recognition of the Irish Free State in 1922. Although the Free State was explicitly governed under dominion status and thus was not a fully independent polity, as a dominion it was no longer considered to be part of the United Kingdom and ceased to be represented in the Westminster Parliament. Six northeastern counties in Ireland, which since 1920 were being governed under a much more limited form of home rule, immediately seceded from the Free State and remained part of the Union under this limited form of self-government. In light of these changes, the British state was renamed the United Kingdom of Great Britain and Northern Ireland on April 12, 1927 with the Royal and Parliamentary Titles Act. The modern-day United Kingdom is the same state, that is to say a direct continuation of what remained after the Irish Free State's secession, as opposed to being an entirely new successor state.

Edward VII (Albert Edward; 9 November 1841 – 6 May 1910) was King of the United Kingdom of Great Britain and Ireland and the British Dominions, and Emperor of India, from 22 January 1901 until his death in 1910.

The eldest son of Queen Victoria and Prince Albert of Saxe-Coburg and Gotha, and nicknamed "Bertie", Edward was related to royalty throughout Europe. He was Prince of Wales and heir apparent to the British throne for almost 60 years. During the long reign of his mother, he was largely excluded from political influence and came to personify the fashionable, leisured elite. He travelled throughout Britain performing ceremonial public duties and represented Britain on visits abroad. His tours of North America in 1860 and of the Indian subcontinent in 1875 proved popular successes, but despite public approval, his reputation as a playboy prince soured his relationship with his mother.

As king, Edward played a role in the modernisation of the British Home Fleet and the reorganisation of the British Army after the Second Boer War of 1899–1902. He re-instituted traditional ceremonies as public displays and broadened the range of people with whom royalty socialised. He fostered good relations between Britain and other European countries, especially France, for which he was popularly called "Peacemaker", but his relationship with his nephew, the German Emperor Wilhelm II, was poor. The Edwardian era, which covered Edward's reign and was named after him, coincided with the start of a new century and heralded significant changes in technology and society, including steam turbine propulsion and the rise of socialism. He died in 1910 in the midst of a constitutional crisis that was resolved the following year by the Parliament Act 1911, which restricted the power of the unelected House of Lords.
