Kingdom Of Prussia
The Kingdom of Prussia (german: Königreich Preußen, ) was a German kingdom that constituted the state of Prussia between 1701 and 1918.Marriott, J. A. R., and Charles Grant Robertson. ''The Evolution of Prussia, the Making of an Empire''. Rev. ed. Oxford: Clarendon Press, 1946. It was the driving force behind the unification of Germany in 1871 and was the leading state of the German Empire until its dissolution in 1918. Although it took its name from the region called Prussia, it was based in the Margraviate of Brandenburg. Its capital was Berlin. The kings of Prussia were from the House of Hohenzollern. Brandenburg-Prussia, predecessor of the kingdom, became a military power under Frederick William, Elector of Brandenburg, known as "The Great Elector".

Eighth Air Force
The Eighth Air Force (Air Forces Strategic) is a numbered air force (NAF) of the United States Air Force's Air Force Global Strike Command (AFGSC). It is headquartered at Barksdale Air Force Base, Louisiana. The command serves as Air Forces Strategic – Global Strike, one of the air components of United States Strategic Command (USSTRATCOM). The Eighth Air Force includes the heart of America's heavy bomber force: the Northrop Grumman B-2 Spirit stealth bomber, the Rockwell B-1 Lancer supersonic bomber, and the Boeing B-52 Stratofortress heavy bomber aircraft. Established on 22 February 1944 by the redesignation of VIII Bomber Command at RAF Daws Hill in High Wycombe, England, the Eighth Army Air Force (8 AAF) was a United States Army Air Forces combat air force in the European Theater of World War II (1939/41–1945), engaging in operations primarily in the Northern Europe area of responsibility; carrying out strategic bombing of enemy targets in France, the Low Countrie ...

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Red Ruhr Army
The Ruhr Red Army (13 March – 12 April 1920) was an army of between 50,000 and 80,000 left-wing workers who conducted what was known as the Ruhr Uprising (''Ruhraufstand''), in the Weimar Republic. It was the largest armed workers' uprising in the nation's history, and ran from 13 March to 2 April, 1920, in Germany's most important industrial area. The workers were reacting to the Kapp Putsch, an effort by right-wing forces in March 1920 to overthrow the elected government. After calling a general strike on 14 March, the Red Ruhr Army defeated the Freikorps and regular army units in the area and started the uprising. The government sent in regular and paramilitary forces, killing an estimated 1,000 workers and suppressing the revolt. Description The workers were drawn from the Communist Party of Germany, the Communist Workers' Party of Germany, the Independent Social Democratic Party of Germany, and the Free Workers Union of Germany. Their army formed in the Ruhr Valley (th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Kapp Putsch
The Kapp Putsch (), also known as the Kapp–Lüttwitz Putsch (), was an attempted coup against the German national government in Berlin on 13 March 1920. Named after its leaders Wolfgang Kapp and Walther von Lüttwitz, its goal was to undo the German Revolution of 1918–1919, overthrow the Weimar Republic, and establish an autocratic government in its place. It was supported by parts of the ''Reichswehr'', as well as nationalist and monarchist factions. Although the legitimate German government was forced to flee the city, the coup failed after a few days, when large sections of the German population joined a general strike called by the government. Most civil servants refused to cooperate with Kapp and his allies. Despite its failure, the Putsch had significant consequences for the future of the Weimar Republic. It was also one of the direct causes of the Ruhr uprising a few weeks later, which the government suppressed by military force, after having dealt leniently with lea ...

Ruhr Area
The Ruhr ( ; german: Ruhrgebiet , also ''Ruhrpott'' ), also referred to as the Ruhr area, sometimes Ruhr district, Ruhr region, or Ruhr valley, is a polycentric urban area in North Rhine-Westphalia, Germany. With a population density of 2,800/km2 and a population of over 5 million (2017), it is the largest urban area in Germany. It consists of several large cities bordered by the rivers Ruhr to the south, Rhine to the west, and Lippe to the north. In the southwest it borders the Bergisches Land. It is considered part of the larger Rhine-Ruhr metropolitan region of more than 10 million people, which is the third largest in Europe, behind only London and Paris.

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ...
