Splendid isolationSplendid isolation is a term used to describe the 19th-century British diplomatic practice of avoiding permanent alliances, particularly under the governments of Lord Salisbury between 1885 and 1902. The concept developed as early as 1822, when Britain left the post-1815 Concert of Europe, and continued until the 1902 Anglo-Japanese Alliance and the 1904 Entente Cordiale with France. As Europe was divided into two power blocs, Britain became aligned with the French Third Republic and the Russian Empire (known as the Triple Entente) against the German Empire, Austria-Hungary and the Kingdom of Italy (The Triple Alliance).
European balance of powerThe European balance of power is a tenet in international relations that no single power should be allowed to achieve hegemony over a substantial part of Europe. During much of the Modern Age, the balance was achieved by having a small number of ever-changing alliances contending for power, which culminated in the World Wars of the early 20th century. By 1945, European-led global dominance and rivalry had ended and the doctrine of European balance of power was replaced by a worldwide balance of power involving the United States and the Soviet Union as the modern superpowers.
International relations (1648–1814)International relations from 1648 to 1814 covers the major interactions of the nations of Europe, as well as the other continents, with emphasis on diplomacy, warfare, migration, and cultural interactions, from the Peace of Westphalia to the Congress of Vienna. Balance of power: The concept of the balance of power emerged as a fundamental principle in international relations during this period. Major powers sought to maintain a delicate equilibrium to prevent the domination of any single state or coalition, often leading to alliances, territorial adjustments, and military interventions.
Causes of World War IThe identification of the causes of World War I remains a debated issue. World War I began in the Balkans on July 28, 1914, and hostilities ended on November 11, 1918, leaving 17 million dead and 25 million wounded. Moreover, the Russian Civil War can in many ways be considered a continuation of World War I, as can various other conflicts in the direct aftermath of 1918. Scholars looking at the long term seek to explain why two rival sets of powers (the German Empire and Austria-Hungary against the Russian Empire, France, the British Empire and later the United States) came into conflict by 1915.
Concert of EuropeThe Concert of Europe was a general consensus among the great powers of 19th-century Europe to maintain the European balance of power, political boundaries, and spheres of influence. Never a perfect unity and subject to disputes and jockeying for position and influence, the Concert was an extended period of relative peace and stability in Europe following the Wars of the French Revolution and Napoleonic Wars which had consumed the continent since the 1790s. There is considerable scholarly dispute over the exact nature and duration of the Concert.
Revolutionary waveA revolutionary wave or revolutionary decade is one series of revolutions occurring in various locations within a similar time-span. In many cases, past revolutions and revolutionary waves have inspired current ones, or an initial revolution has inspired other concurrent "affiliate revolutions" with similar aims. The causes of revolutionary waves have become the subjects of study by historians and political philosophers, including Robert Roswell Palmer, Crane Brinton, Hannah Arendt, Eric Hoffer, and Jacques Godechot.
International relations (1919–1939)International relations (1919–1939) covers the main interactions shaping world history in this era, known as the interwar period, with emphasis on diplomacy and economic relations. The coverage here follows the diplomatic history of World War I and precedes the diplomatic history of World War II.
Pax BritannicaPax Britannica (Latin for "British Peace", modelled after Pax Romana) was the period of relative peace between the great powers during which the British Empire became the global hegemonic power and adopted the role of a "global policeman". Between 1815 and 1914, a period referred to as Britain's "imperial century", around of territory and roughly 400 million people were added to the British Empire. Victory over Napoleonic France left the British without any serious international rival, other than perhaps Russia in Central Asia.
Victorian eraIn the history of the United Kingdom and the British Empire, the Victorian era was the period of Queen Victoria's reign, from 20 June 1837 until her death on 22 January 1901. Slightly different definitions are sometimes used. The era followed the Georgian era and preceded the Edwardian era, and its later half overlaps with the first part of the Belle Époque era of continental Europe. Various liberalising political reforms took place in the UK including expanding the electoral franchise.
Eastern questionIn diplomatic history, the Eastern question was the issue of the political and economic instability in the Ottoman Empire from the late 18th to early 20th centuries and the subsequent strategic competition and political considerations of the European great powers in light of this. Characterized as the "sick man of Europe", the relative weakening of the empire's military strength in the second half of the eighteenth century threatened to undermine the fragile balance of power system largely shaped by the Concert of Europe.
