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)., Hawaii is the 50th and most recent state to have joined the United States of America, having received statehood on August 21, 1959. Hawaii is the only U.S. state located in Oceania and the only one composed entirely of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean. Hawaii is the only U.S. state not located in the Americas., 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., 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., 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., The were a pair of dreadnought battleships built for the Imperial Japanese Navy ( IJN ) during World War I , although they were not completed until after the end of the war . , the lead ship of the class , frequently served as a flagship . Both ships carried supplies for the survivors of the Great Kant earthquake in 1923 . They were modernized in 1933 -- 36 with improvements to their armor and machinery and a rebuilt superstructure in the pagoda mast style . Nagato and her sister ship briefly participated in the Second Sino - Japanese War in 1937 and Nagato was the flagship of Admiral Isoroku Yamamoto during the attack on Pearl Harbor on 7 December 1941 that began the Pacific War ., 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., The dreadnought was the predominant type of battleship in the early 20th century. The first of its kind, the Royal Navy's , made such a strong impression on people's minds when launched in 1906 that similar battleships built subsequently were referred to generically as "dreadnoughts", and earlier battleships became known as "pre-dreadnoughts". "Dreadnought"s design had two revolutionary features: an "all-big-gun" armament scheme, with more heavy-calibre guns than previous ships, and steam turbine propulsion. As dreadnoughts became a symbol of national power, the arrival of these new warships was a crucial catalyst in the intensifying naval arms race between the United Kingdom and Germany. With the launch of a single ship, "Dreadnought", the scales of naval power were reset overnight. As a result, dreadnought races sprang up around the world, including in South America, during the lead up to World War I. Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era. Within five years, new battleships had outclassed "Dreadnought". These more powerful vessels were known as "super-dreadnoughts." Most of the original dreadnoughts were scrapped after the end of World War I under the terms of the Washington Naval Treaty, but many of the newer super-dreadnoughts continued to be used throughout World War II. The only surviving dreadnought is , located near the San Jacinto Battleground State Historic Site., A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884., 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.

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., The San Jacinto Battleground State Historic Site includes the location of the Battle of San Jacinto, and the USS "Texas". It is located off the Houston Ship Channel in unincorporated Harris County, Texas near the city of Houston. The site was designated a National Historic Landmark in 1960., The Washington Naval Treaty, also known as the Five-Power Treaty, and including the "Four-Power Treaty" and the "Nine-power Treaty" was a treaty among the major nations that had won World War I, which agreed to prevent an arms race by limiting naval construction. It was negotiated at the Washington Naval Conference, held in Washington, D.C., from November 1921 to February 1922, and it was signed by the governments of the United Kingdom, the United States, Japan, France, and Italy. It limited the construction of battleships, battlecruisers and aircraft carriers by the signatories. The numbers of other categories of warships, including cruisers, destroyers and submarines, were not limited by the treaty, but those ships were limited to 10,000 tons displacement., 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 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 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., 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 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).
Names.
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 attack on Pearl Harbor, also known as the Battle of Pearl Harbor, the Hawaii Operation or Operation AI by the Japanese Imperial General Headquarters, and Operation Z during planning, was a surprise military strike by the Imperial Japanese Navy Air Service against the United States naval base at Pearl Harbor, Hawaii Territory, on the morning of December 7, 1941. The attack led to the United States' entry into World War II., 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 as part of the Supreme War Council was established in 1893 to coordinate efforts between the Imperial Japanese Army and Imperial Japanese Navy during wartime. In terms of function, it was approximately equivalent to the United States Joint Chiefs of Staff and the British Chiefs of Staff Committee., 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., Subject: nagato-class battleship, Relation: service_entry, Options: (A) 1868 (B) 1884 (C) 1887 (D) 1893 (E) 1894 (F) 1895 (G) 1906 (H) 1913 (I) 1914 (J) 1918 (K) 1920 (L) 1921 (M) 1922 (N) 1931 (O) 1933 (P) 1937 (Q) 1939 (R) 1941 (S) 1943 (T) 1945 (U) 1946 (V) 1947 (W) 1959 (X) 1960 (Y) 7
