World War IWorld War I or the First World War, often abbreviated as WWI or WW1, known contemporaneously as the Great War, was a major global conflict lasting from 1914 to 1918. It was fought between two coalitions, the Allies and the Central Powers. Fighting took place throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. The first decade of the 20th century saw increasing diplomatic tension between the European great powers.
Interwar periodIn the history of the 20th century, the interwar period (or interbellum) lasted from 11November 1918 to 1September 1939 (20years, 9months, 21 days)the end of the First World War to the beginning of the Second World War. The interwar period was relatively short, yet featured many significant social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of both social mobility and economic mobility for the middle class.
Allies of World War IThe Allies, or the Entente Powers, were an international military coalition of countries led by France, the United Kingdom, Russia, the United States, Italy, and Japan against the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, and 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.
German colonial empireThe German colonial empire (Deutsches Kolonialreich) constituted the overseas colonies, dependencies, and territories of the German Empire. Unified in the early 1870s, the chancellor of this time period was Otto von Bismarck. Short-lived attempts at colonization by individual German states had occurred in preceding centuries, but Bismarck resisted pressure to construct a colonial empire until the Scramble for Africa in 1884. Claiming much of the remaining uncolonized areas of Africa, Germany built the third-largest colonial empire at the time, after the British and French.
Allies of World War IIThe Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, the Empire of Japan, and the Kingdom of Italy. Its principal members by the end of 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India.
LorraineLorraine is a cultural and historical region in Northeastern France, now located in the administrative region of Grand Est. Its name stems from the medieval kingdom of Lotharingia, which in turn was named after either Emperor Lothair I or King Lothair II. Lorraine later was ruled as the Duchy of Lorraine before the Kingdom of France annexed it in 1766. From 1982 until January 2016, Lorraine was an administrative region of France. In 2016, under a reorganisation, it became part of the new region Grand Est.
Pan-GermanismPan-Germanism (Pangermanismus or Alldeutsche Bewegung), also occasionally known as Pan-Germanicism, is a pan-nationalist political idea. Pan-Germanists originally sought to unify all the German-speaking people – and possibly also non-German Germanic-speaking peoples – in a single nation-state known as the Greater Germanic Reich (Großgermanisches Reich), fully styled the Greater Germanic Reich of the German Nation (Großgermanisches Reich der Deutschen Nation).
Former eastern territories of GermanyThe "former eastern territories of Germany" (Ehemalige deutsche Ostgebiete) refer in present-day Germany to those territories east of the current eastern border of Germany i.e. the Oder–Neisse line which historically had been considered German and which were annexed by Poland and the Soviet Union after World War II in Europe. In many of these territories, Germans used to be the dominant or sole ethnicity.

Ethnic nationalismEthnic nationalism, also known as ethnonationalism, is a form of nationalism wherein the nation and nationality are defined in terms of ethnicity, with emphasis on an ethnocentric (and in some cases an ethnocratic) approach to various political issues related to national affirmation of a particular ethnic group. The central tenet of ethnic nationalists is that "nations are defined by a shared heritage, which usually includes a common language, a common faith, and a common ethnic ancestry".
