History of the Great WarThe History of the Great War Based on Official Documents by Direction of the Committee of Imperial Defence (abbreviated to History of the Great War or British Official History) is a series of 109 volumes, concerning the war effort of the British state during the First World War. It was produced by the Historical Section of the Committee of Imperial Defence from 1915 to 1949; after 1919 Brigadier-General Sir James Edmonds was Director. Edmonds wrote many of the army volumes and influenced the choice of historians for the navy, air force, medical and veterinary volumes.
Artillery observerAn artillery observer, artillery spotter, or forward observer (FO) is a soldier responsible for directing artillery and mortar fire support onto a target. An artillery observer usually accompanies a tank or infantry unit. Spotters ensure that indirect fire hits targets which those at a fire support base cannot see. Historically, the range of artillery steadily increased over the centuries. In the era of bombards or Steinbüchse, the gunner could usually still fire directly on the target by line-of-sight.
Sister cityA sister city or a twin town relationship is a form of legal or social agreement between two geographically and politically distinct localities for the purpose of promoting cultural and commercial ties. While there are early examples of international links between municipalities akin to what are known as sister cities or twin towns today dating back to the 9th century, the modern concept was first established and adopted worldwide during World War II. The modern concept of town twinning has its roots in the Second World War.
Millet (Ottoman Empire)In the Ottoman Empire, a millet (millet; مِلَّة) was an independent court of law pertaining to "personal law" under which a confessional community (a group abiding by the laws of Muslim Sharia, Christian Canon law, or Jewish Halakha) was allowed to rule itself under its own laws. Despite frequently being referred to as a "system", before the nineteenth century the organization of what are now retrospectively called millets in the Ottoman Empire was not at all systematic.
Minister of MunitionsThe Minister of Munitions was a British government position created during the First World War to oversee and co-ordinate the production and distribution of munitions for the war effort. The position was created in response to the Shell Crisis of 1915 when there was much newspaper criticism of the shortage of artillery shells and fear of sabotage. The Ministry was created by the Munitions of War Act 1915 passed on 2 July 1915 to safeguard the supply of artillery munitions.
Reinsurance TreatyThe Reinsurance Treaty was a diplomatic agreement between the German Empire and the Russian Empire that was in effect from 1887 to 1890. Only a handful of top officials in Berlin and St. Petersburg knew of its existence since it was so secret. The treaty played a critical role in German Chancellor Otto von Bismarck's extremely complex and ingenious network of alliances and agreements, which aimed to keep the peace in Europe and to maintain Germany's economic, diplomatic and political dominance.
Radomir (town)Radomir (Радомир ˈradomir) is a town in the Radomir Municipality in the Pernik Province of Bulgaria. The town of Radomir is located at 764 meters above sea level in the Radomir valley, at the foot of Mount Golo Bardo. It is the center of the historical-geographical region of Mraka. The climate is humid-continental (Dfb). The town was first mentioned in a 15th-century source as Uradmur. The current form appears for the first time in a source from 1488. The name is derived directly from the personal name Radomir or its adjectival form.
German EmpireThe German Empire (Deutsches Kaiserreich), also referred to as Imperial Germany, the Second Reich, or simply Germany, was the period of the German Reich from the unification of Germany in 1871 until the November Revolution in 1918, when the German Reich changed its form of government from a monarchy to a republic. The empire was founded on 18 January 1871, when the south German states, except for Austria, Switzerland, and Liechtenstein, joined the North German Confederation and the new constitution came into force on April 16, changing the name of the federal state to the German Empire and introducing the title of German Emperor for Wilhelm I, King of Prussia from the House of Hohenzollern.
Aisne (river)The Aisne (eɪn , USalsoɛn , ɛːn) is a river in northeastern France. It is a left tributary of the Oise. It gave its name to the French department of Aisne. It was known in the Roman period as Axona. The river rises in the forest of Argonne, at Rembercourt-Sommaisne, near Sainte-Menehould. It flows north and then west before joining the Oise near Compiègne. The Aisne is long. Its main tributaries are the Vesle, the Aire and the Suippe. The Battle of the Axona was fought near there between the Romans and the Belgae in 57 BC.
Railway gunA railway gun, also called a railroad gun, is a large artillery piece, often surplus naval artillery, mounted on, transported by, and fired from a specially designed railway wagon. Many countries have built railway guns, but the best-known are the large Krupp-built pieces used by Germany in World War I and World War II. Smaller guns were often part of an armoured train. Only able to be moved where there were good tracks, which could be destroyed by artillery bombardment or airstrike, railway guns were phased out after World War II.
