World Wars in the context of "Key events of the 20th century"

The 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.

In world-systems theory, core countries (or the imperial core) are the industrialized capitalist and/or imperialist countries. Core countries control and benefit the most resources from the global market. They are usually recognized as wealthy states with a wide variety of resources and are in a favorable location compared to other states. They have strong state institutions, a powerful military, and powerful global political alliances. In the 20th-21st centuries they consist of Australia, New Zealand, Canada, Western European countries, Japan, the United Kingdom, and the United States. The population of the core countries is on average by far the wealthiest of the world, with the highest life expectancy, literacy rate, best education and social welfare on the planet.

Core countries do not always stay "core" permanently. Throughout world history, core countries have been changing, and new ones have been added to the "core" list. These were the Asian, Indian, and Middle Eastern empires in the ages up to the 16th century; prominently Medieval India and the Chinese Empire, which were the richest regions in the world until the European Great Powers took the lead during the early modern period, although the major Asian powers were still very influential in the region. Europe remained ahead of the pack until the 20th century, when the two World Wars were disastrous for the European economies. It was then that the victorious United States and Soviet Union, up to the late 1980s, became the two hegemonic powers, creating a bipolar world order during the Cold War. In 1991, the collapse of the Soviet Union left the United States as the world’s sole remaining superpower, sometimes referred to as a hyperpower.

The predecessors to the contemporary Army of India were many: the sepoy regiments, native cavalry, irregular horse and Indian sapper and miner companies raised by the three British presidencies. The Army of India was raised under the British Raj in the 19th century by taking the erstwhile presidency armies, merging them, and bringing them under the Crown. The British Indian Army fought in both World Wars.

The armed forces succeeded the military of British India following India's independence in 1947. After World War II, many of the wartime troops were discharged and units disbanded. The reduced armed forces were partitioned between India and Pakistan. The Indian Armed Forces fought in all four wars against Pakistan, and two wars against People's Republic of China in 1962 and 1967. India also fought in the Kargil War with Pakistan in 1999, the highest altitude mountain warfare in history.

The Monument of Remembrance (French: Monument du souvenir), usually known by the nickname of the Gëlle Fra (Luxembourgish for 'Golden Lady'), is a war memorial in Luxembourg City. It is dedicated to the thousands of Luxembourgers who volunteered for service in the armed forces of the Allied Powers during both World Wars and the Korean War as well as the Luxembourgers who volunteered in the International Brigades during the Spanish Civil War.

A capital levy is a tax on capital rather than income, collected once, rather than repeatedly (regular collection would make it a wealth tax). For example, a capital levy of 30% will see an individual or business with a net worth of $100,000 pay a one-off sum of $30,000, regardless of income. Capital levies are considered difficult for a government to implement.

Some economists argue that capital levies are a disincentive to savings and investment, and cause capital flight, but others argue that in theory this need not be the case. The latter view was popular in the World Wars; in the 2010s, it has also gained some acceptance as more heavily indebted nations struggle to raise revenues.

André Paul Guillaume Gide (French: [ɑ̃dʁe pɔl ɡijom ʒid]; 22 November 1869 – 19 February 1951) was a French author whose writing spanned a wide variety of styles and topics. He was awarded the 1947 Nobel Prize in Literature. Gide's career ranged from his beginnings in the symbolist movement to criticising imperialism between the two World Wars. Author of more than 50 books, he was described in his New York Times obituary as "France's greatest contemporary man of letters" and "judged the greatest French writer of this century by the literary cognoscenti."

Known for his fiction as well as his autobiographical works, Gide expressed the conflict and eventual reconciliation of the two sides of his personality (characterized by a Protestant austerity and a transgressive sexual adventurousness, respectively). As a self-professed pederast, he used his writing to explore his struggle to be fully oneself, including owning one's sexual nature, without betraying one's values. His political activity was shaped by the same ethos. While sympathetic to Communism in the early 1930s, like many intellectuals, after his 1936 journey to the USSR he supported the anti-Stalinist left; during the 1940s he shifted towards more traditional values and repudiated Communism as an idea that breaks with the traditions of Christian civilization.

A blockade runner is a merchant vessel used for evading a naval blockade of a port or strait. It is usually light and fast, using stealth and speed rather than confronting the blockaders in order to break the blockade. Blockade runners usually transport cargo, for example bringing food or arms to a blockaded city. They have also carried mail in an attempt to communicate with the outside world.

Blockade runners are often the fastest ships available, and come lightly armed and armored. Their operations are quite risky since blockading fleets would not hesitate to fire on them. However, the potential profits (economically or militarily) from a successful blockade run are tremendous, so blockade-runners typically had excellent crews. Although having modus operandi similar to that of smugglers, blockade-runners are often operated by states' navies as part of the regular fleet; states having operated them include the Confederate States of America during the American Civil War, and Germany during the World Wars.
