Context: World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history., The Marco Polo Bridge Incident, also known by several other names, was a battle between the Republic of China's National Revolutionary Army and the Imperial Japanese Army. It is often used as the marker for the start of the Second Sino-Japanese War (19371945).

In English, the battle is usually known as the "Marco Polo Bridge Incident". The Marco Polo Bridge is an eleven-arch granite bridge, an architecturally significant structure first erected under the Jin and later restored by the Kangxi Emperor in 1698. It gained its Western name from its appearance in Marco Polo's record of his travels. The name is less often expressed as the , The , or JMSDF, is the naval branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. It was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships and 346 aircraft. Its main tasks are to maintain control of the nation's sea lanes and to patrol territorial waters. It also participates in UN-led peacekeeping operations (PKOs) and Maritime Interdiction Operations (MIOs)., The Emperor of Japan is the head of the Imperial Family and is the ceremonial head of state of Japan's system of constitutional monarchy. According to the 1947 constitution, he is "the symbol of the State and of the unity of the people." Historically, he is also the highest authority of the Shinto religion as he and his family are said to be the direct descendants of the sun-goddess Amaterasu, and his importance also lies in dealing with heavenly affairs, including Shinto ritual and rites throughout the nation., The First Sino-Japanese War (1 August 1894  17 April 1895) was fought between the Qing Empire of China and the Empire of Japan, primarily over control of Korea. After more than six months of unbroken successes by Japanese land and naval forces and the loss of the Chinese port of Weihaiwei, the Qing government sued for peace in February 1895., The was the historical Japanese nation-state and great power that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan., The Second Sino-Japanese War (September 18, 1931  September 9, 1945) was a military conflict fought primarily between the Republic of China and the Empire of Japan from 1931 to 1945. The First Sino-Japanese War happened in 189495. In January 2017, the Chinese Government extended their official definition of the Second Sino-Japanese War back to September 18, 1931  the Invasion of Manchuria by Japan  as opposed to the traditional 1937 start date, defined by the Marco Polo Bridge Incident.
China fought Japan, with some economic help from Germany, the Soviet Union and the United States. After the Japanese attack on Pearl Harbor in 1941, the war would merge into the greater conflict of World War II as a major front of what is broadly known as the Pacific War. One could call the Second Sino-Japanese War part of World War II, but the latter conflict is still mainly considered to have started in 1939 when France and the British Empire declared war on Nazi Germany following the invasion of Poland. The Second Sino-Japanese War was the largest Asian war in the 20th century. It accounted for the majority of civilian and military casualties in the Pacific War, with anywhere between 10 and 25 million Chinese civilians and over 4 million Chinese and Japanese military personnel dying from war-related violence, famine, and other causes., The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, % of the world population at the time, and by 1920, it covered , % of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories., Japan ("Nippon" or "Nihon" ; formally "" or "Nihon-koku", means "State of Japan") is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, It is lying off the eastern coast of the Asia Mainland (east of China, Korea, Russia) and stretching from the Sea of Okhotsk in the north to the East China Sea and near Taiwan in the southwest. , The , literally "Army of the Greater Japanese Empire", was the official ground-based armed force of the Empire of Japan, from 1871 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of War, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the navy. Later an Inspectorate General of Military (Army) Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad-hoc body consisting of the chief and vice chief of the Army General Staff, the minister of war, the chief and vice chief of the Naval General Staff, the inspector general of military aviation, and the inspector general of military training., Manchuria is a modern name, first created by Japanese, given to a large geographic region in Northeast Asia. Depending on the context, Manchuria can either refer to a region that falls entirely within the People's Republic of China, or a larger region divided between China and Russia. The region that falls entirely within modern China is now usually referred to as Northeast China in China, although "Manchuria" is widely used outside of China to denote the geographical and historical region. This region is the traditional homeland of the Xianbei, Khitan, and Jurchen (later called Manchu) peoples, who built several states historically, although no term for "Manchuria" exists in the Manchu language, which originally referred to the area as the "Three Eastern Provinces"., The Invasion of Poland, also known as the September Campaign, or the 1939 Defensive War in Poland (or "Wojna obronna 1939 roku"), and alternatively the Poland Campaign or "Fall Weiss" in Germany (Case White), was a joint invasion of Poland by Nazi Germany, the Free City of Danzig, the Soviet Union, and a small Slovak contingent, that marked the beginning of World War II in Europe. The German invasion began on 1 September 1939, one week after the signing of the MolotovRibbentrop Pact, while the Soviet invasion commenced on 17 September following the Molotov-Tg agreement that terminated the Russian and Japanese hostilities in the east on 16 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German-Soviet Frontier Treaty., The United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, during the final stage of World War II. The United States had dropped the bombs with the consent of the United Kingdom as outlined in the Quebec Agreement. The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history., The Soviet Union, officially the Union of Soviet Socialist Republics (USSR " ) was a socialist state in Eurasia that existed from 1922 to 1991. A union of multiple subnational republics, its government and economy were highly centralized. The Soviet Union was a one-party federation, governed by the Communist Party with Moscow as its capital., World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved., The Holocaust (from the Greek ': "hólos", "whole" and "kaustós", "burnt"), also referred to as the Shoah"' (Hebrew: , "HaShoah", "the catastrophe"), was a genocide in which Adolf Hitler's Nazi Germany and its collaborators killed about six million Jews. The victims included 1.5 million children and represented about two-thirds of the nine million Jews who had resided in Europe. Some definitions of the Holocaust include the additional five million non-Jewish victims of Nazi mass murders, bringing the total to about 11 million. Killings took place throughout Nazi Germany, German-occupied territories, and territories held by allies of Nazi Germany., The Type 97 Hand Grenade (  Kynana - shiki Terydan ) was the standard fragmentation hand grenade of the Imperial Japanese Army and Imperial Japanese Navy SNLF during the Second Sino - Japanese War and World War II., Kyjitai, literally "old character forms" (Kyjitai: or ), are the traditional forms of kanji, Chinese written characters used in Japanese. Their simplified counterparts are shinjitai, "new character forms". Some of the simplified characters arose centuries ago and were in everyday use in both China and Japan, but they were considered inelegant, even uncouth. After World War II, simplified character forms were made official in both these countries. However, in Japan fewer and less drastic simplifications were made: e.g. "electric" is still written as in Japan, as it is also written in Hong Kong, Macao, South Korea and Taiwan, which continue to use traditional Chinese characters, but has been simplified to in mainland China. Prior to the promulgation of the Ty kanji list in 1946, kyjitai were known as "seiji" (meaning "proper/correct characters") or "seijitai". Even after "kyjitai" were officially marked for discontinuation with the promulgation of the Ty kanji list, they were used in print frequently into the 1950s due to logistical delays in changing over typesetting equipment. "Kyjitai" continue in use to the present day because when the Japanese government adopted the simplified forms, it did not ban the traditional forms. Thus traditional forms are used when an author wishes to use traditional forms and the publisher agrees., The Pacific War, sometimes called the Asia-Pacific War, was the theater of World War II that was fought in the Pacific and East Asia. It was fought over a vast area that included the Pacific Ocean and islands, the South West Pacific, South-East Asia, and in China (including the 1945 SovietJapanese conflict)., The Imperial Japanese Navy (IJN; Kyjitai: Shinjitai: "" or "Nippon Kaigun", "Navy of the Greater Japanese Empire") was the navy of the Empire of Japan from 1868 until 1945, when it was dissolved following Japan's defeat and surrender in World War II. It was controlled by the Imperial Japanese Navy General Staff and the Ministry of the Navy, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the navy. The Japan Maritime Self-Defense Force (JMSDF) was formed after the dissolution of the IJN., Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party (NSDAP). Under Hitler's rule, Germany was transformed into a fascist state in which the Nazi Party took totalitarian control over nearly all aspects of life. The official name of the state was "Deutsches Reich" from 1933 to 1943 and "Großdeutsches Reich" ("Greater German Reich") from 1943 to 1945. The period is also known under the names the Third Reich and the National Socialist Period (abbreviated as "NS-Zeit"). The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945, ending World War II in Europe., Pearl Harbor is a lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. Much of the harbor and surrounding lands is a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The attack on Pearl Harbor by the Empire of Japan on December 7, 1941 was the immediate cause of the United States' entry into World War II., Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe.
