World War I
World War I was a military conflict centered on Europe that began in the summer of 1914. The fighting ended in late 1918. This conflict involved most of the world's great powers, assembled in two opposing alliances: the Allies (centred around the Triple Entente) and the Central Powers. More than 70 million military personnel, including 60 million Europeans, were mobilized in one of the largest wars in history. More than 15 million people were killed, making it also one of the deadliest conflicts in history. The war is also known as the First World War, the Great War, the World War (prior to the outbreak of World War II), and the War to End All Wars.
The assassination on 28 June 1914 of Archduke Franz Ferdinand of Austria, the heir to the throne of Austria-Hungary, is seen as the immediate trigger of the war, though long-term causes, such as imperialistic foreign policies of the great powers of Europe such as the German Empire, the Austro-Hungarian Empire, the Ottoman Empire, the Russian Empire, the British Empire, France, and Italy played a major role. Ferdinand's assassination at the hands of a Yugoslav nationalist resulted in Habsburg ultimatum against the Kingdom of Serbia. Several alliances that had been formed over the past decades were invoked, so within weeks the major powers were at war; as all had colonies, the conflict soon spread around the world.
The conflict opened with the German invasion of Belgium, Luxembourg and France; the Austro-Hungarian invasion of Serbia and a Russian attack against Prussia. After the German march on Paris was brought to a halt, the Western Front settled into a static battle of attrition with a trench line that changed little until 1917. In the East, the Russian army successfully fought against the Austro-Hungarian forces but was forced back by the German army. Additional fronts opened after the Ottoman Empire joined the war in 1914, Italy and Bulgaria in 1915 and Romania in 1916. The Russian Empire collapsed in 1917, and Russia left the war after the October Revolution later that year. After a 1918 German offensive along the western front, American forces entered the trenches and the German armies were driven back in a series of successful allied offensives. Germany surrendered on Armistice Day, November 11, 1918.
By the war's end, four major imperial powers—the German, Russian, Austro-Hungarian and Ottoman Empires—had been militarily and politically defeated, and the last two ceased to exist. The revolutionized Soviet Union emerged from the Russian Empire, while the map of central Europe was completely redrawn into numerous smaller states. The League of Nations was formed in the hope of preventing another such conflict. The European nationalism spawned by the war, the repercussions of Germany's defeat, and of the Treaty of Versailles would eventually lead to the beginning of World War II in 1939.
Triple Alliance (1882)
The Triple Alliance was the military alliance between Germany, Austria–Hungary, and Italy that lasted from 1882 until the start of World War I in 1914. Each member promised mutual support in the event of an attack by any two other great powers, or for Germany and Italy, an attack by France alone. In a supplementary declaration, Italy specified that its undertakings could not be regarded as being directed against the United Kingdom of Great Britain and Ireland. Shortly after renewing the Alliance in June 1902, Italy secretly extended a similar guarantee to France.
When Germany and Austria–Hungary found themselves at war in August 1914 with the rival Triple Entente of Britain, France, and the latter's ally, Russia, Italy pledged its support to the Central Powers, but Italy did not enter into the war because the Triple Alliance was a defensive alliance, and Germany and Austria–Hungary had taken the offensive. Subsequently Italy entered the conflict on the side of the Entente against Austria–Hungary in May 1915 and Germany in August 1916.

World War II
World War II, or the Second World War(often abbreviated as WWII or WW2), was a global military conflict lasting from 1939 to 1945 which involved most of the world's nations, including all of the great powers, organised into two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, with more than 100 million military personnel mobilised. In a state of "total war", the major participants placed their entire economic, industrial, and scientific capabilities at the service of the war effort, erasing the distinction between civilian and military resources. Marked by significant action against civilians, including the Holocaust and the only use of nuclear weapons in warfare, it was the deadliest conflict in human history, and it has been estimated that it resulted in fifty million to over seventy million fatalities.
The war is generally accepted to have begun on 1 September 1939, with the invasion of Poland by Nazi Germany and subsequent declarations of war on Germany by France and most of the countries of the British Empire and Commonwealth. China and Japan were already at war by this date, whereas other countries that were not initially involved joined the war later in response to events such as the German invasion of the Soviet Union and the Japanese attacks on the U.S. Pacific Fleet at Pearl Harbor and on British overseas colonies, which triggered declarations of war on Japan by the United States, the British Commonwealth,and the Netherlands.
The war ended with the total victory of the Allies over Germany and Japan in 1945. World War II left the political alignment and social structure of the world significantly changed. While the United Nations was established to foster international cooperation and prevent future conflicts, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next forty-six years. Meanwhile, the acceptance of the principle of self-determination accelerated decolonization movements in Asia and Africa, while Western Europe began moving toward economic recovery and increased political integration.
Sunday December 7, 1941
Aircraft and midget submarines of the Imperial Japanese Navy began an attack on the U.S. The Americans had deciphered Japan's code earlier and knew about a planned attack before it actually occurred. However, due to difficulty in deciphering intercepted messages, the Americans failed to discover Japan's target location before the attack occurred.Under the command of Admiral Isoroku Yamamoto, the attack was devastating in loss of life and damage to the U.S. fleet. At 06:05 on December 7, the six Japanese carriers launched a first wave of 183 planes composed mainly of dive bombers, horizontal bombers and fighters.The Japanese hit American ships and military installations at 07:51. The first wave attacked military airfields of Ford Island. At 08:30, a second wave of 170 Japanese planes, mostly torpedo bombers, attacked the fleet anchored in Pearl Harbor. The battleship Arizona was hit with an armor piercing bomb which penetrated the forward ammunition compartment, blowing the ship apart and sinking it within seconds. Overall, nine ships of the U.S. fleet were sunk and 21 ships were severely damaged. Three of the 21 would be irreparable. The overall death toll reached 2,350, including 68 civilians, and 1,178 injured. Of the military personnel lost at Pearl Harbor, 1,177 were from the Arizona. The first shots fired were from the destroyer Ward on a midget submarine that surfaced outside of Pearl Harbor; Ward sank the midget sub at approximately 06:55, about an hour before the assault on Pearl Harbor. Japan would lose 29 out of the 350 planes they attacked with.
The Triple Entente (from French entente [ɑ̃tɑ̃t] "agreement") was the name given to the alliance between the Great Britain, the French Third Republic, and Russia after the signing of the Anglo-Russian Entente in 1907. The Franco-Russian Alliance, along with the Anglo-Russian Entente and the Entente Cordiale, formed the Triple Entente between the British Empire, France and Russia. This was an effective deterrent to the Triple Alliance of the Central Powers and also a plan by the French to encircle Germany.
The alliance of the three powers, supplemented by various agreements with Portugal, Japan, the United States, and Spain, constituted a powerful counterweight to the Triple Alliance of Germany, Austria-Hungary, and Italy, the third having concluded an additional secret agreement with France effectively nullifying their alliance commitments.
On August 9, 1945, Nagasaki was the target of the world's second atomic bomb attack (and second plutonium bomb; the first was tested in New Mexico, USA) at 11:02 a.m., when the north of the city was destroyed and an estimated 40,000 people were killed by the bomb nicknamed "Fat Man." According to statistics found within Nagasaki Peace Park, the death toll from the atomic bombing totaled 73,884, as well as another 74,909 injured, and another several hundred thousand diseased and dying due to fallout and other illness caused by radiation.
The city was rebuilt after the war, albeit dramatically changed. New temples were built, as well as new churches due to an increase in the presence of Christianity. Nagasaki is the seat of a Roman Catholic Archdiocese led by Archbishop Joseph Mitsuaki Takami. Some of the rubble was left as a memorial, such as a one-legged torii gate and an arch near ground zero. New structures were also raised as memorials, such as the Atomic Bomb Museum. Nagasaki remains first and foremost a port city, supporting a rich shipping industry and setting a strong example of perseverance and peace.
On January 4, 2005 the towns of Iōjima, Kōyagi, Nomozaki, Sanwa, Sotome and Takashima, all from Nishisonogi District, were merged into Nagasaki.
