The Empire of Japan aimed to dominate Asia and the Pacific and was already at war with the Republic of China in 1937,but the world war is generally said to have begun on 1 September 1939[6] with the invasion of Poland by Germany and subsequent declarations of war on Germany by France and the United Kingdom. From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Following the Molotov–Ribbentrop Pact, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, including Poland, Finland and the Baltic states. The United Kingdom and the British Commonwealth were the only Allied forces continuing the fight against the Axis, with campaigns in North Africa and the Horn of Africa as well as the long-running Battle of the Atlantic. In June 1941, the European Axis powers launched an invasion of the Soviet Union, opening the largest land theatre of war in history, which trapped the major part of the Axis' military forces into a War of Attrition. In December 1941, Japan attacked the United States and European territories in the Pacific Ocean, and quickly conquered much of the Western Pacific.
The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, and Germany was defeated in North Africa and then, decisively, at Stalingrad in the Soviet Union. In 1943, with a series of German defeats on the Eastern Front, the Allied invasion of Italy which brought about Italian surrender, and Allied victories in the Pacific, the Axis lost the initiative and undertook strategic retreat on all fronts. In 1944, the Western Allies invaded France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy and captured key Western Pacific islands.
The war in Europe ended with an invasion of Germany by the Western Allies and the Soviet Union culminating in the capture of Berlin by Soviet and Polish troops and the subsequent German unconditional surrender on 8 May 1945. Following the Potsdam Declaration by the Allies on 26 July 1945, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on 6 August and 9 August respectively. With an invasion of the Japanese archipelago imminent, the possibility of additional atomic bombings, and the Soviet Union's declaration of war on Japan and invasion of Manchuria, Japan surrendered on 15 August 1945. Thus ended the war in Asia, and the final destruction of the Axis bloc.
World War II altered the political alignment and social structure of the world. The United Nations (UN) was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, and France—became the permanent members of the United Nations Security Council.The Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia and Africa began. Most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities and to create a common identity.
Chronology
See also: Timeline of World War II
The start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland; Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931.
Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and the two wars merged in 1941. This article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of the Second World War as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939.
The exact date of the war's end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945 (V-J Day), rather than the formal surrender of Japan (2 September 1945); it is even claimed in some European histories that it ended on V-E Day (8 May 1945).[citation needed] A peace treaty with Japan was signed in 1951 to formally tie up any loose ends such as compensation to be paid to Allied prisoners of war who had been victims of atrocities.A treaty regarding Germany's future allowed the reunification of East and West Germany to take place in 1990 and resolved other post-World War II issues.
Background
Main article: Causes of World War II
World War I had radically altered the political European map, with the defeat of the Central Powers—including Austria-Hungary, Germany and the Ottoman Empire—and the 1917 Bolshevik seizure of power in Russia. Meanwhile, existing victorious Allies such as France, Belgium, Italy, Greece and Romania gained territories, and new Nation states were created out of the collapse of Austria-Hungary and the Ottoman and Russian Empires.
To prevent a future world war, the League of Nations was created during the 1919 Paris Peace Conference. The organisation's primary goals were to prevent armed conflict through collective security, military and naval disarmament, and settling international disputes through peaceful negotiations and arbitration.
Despite strong pacifist sentiment after World War I,[18] its aftermath still caused irredentist and revanchist nationalism in several European states.These sentiments were especially marked in Germany because of the significant territorial, colonial, and financial losses incurred by the Treaty of Versailles. Under the treaty, Germany lost around 13 percent of its home territory and all of its overseas colonies, while German annexation of other states was prohibited, reparations were imposed, and limits were placed on the size and capability of the country's armed forces. In addition, the Russian Civil War had led to the creation of the Soviet Union.
The German Empire was dissolved in the German Revolution of 1918–1919, and a democratic government, later known as the Weimar Republic, was created. The interwar period saw strife between supporters of the new republic and hardline opponents on both the right and left. Italy, as an Entente ally, had made some post-war territorial gains, however Italian nationalists were angered that the promises made by Britain and France to secure Italian entrance into the war were not fulfilled with the peace settlement. From 1922 to 1925, the Fascist movement led by Benito Mussolini seized power in Italy with a nationalist, totalitarian, and class collaborationist agenda that abolished representative democracy, repressed socialist, left-wing and liberal forces, and pursued an aggressive expansionist foreign policy aimed at forging Italy as a world power, promising the creation of a "New Roman Empire".
The League of Nations assembly, held in Geneva, Switzerland, 1930
In Germany, the Weimar Republic was attacked by right-wing elements such as the Freikorps and the Nazi party, resulting in events such as the Kapp Putsch and the Beer Hall Putsch. With the onset of the Great Depression in 1929, domestic support for Nazism and its leader Adolf Hitler rose and, in 1933, he was appointed Chancellor of Germany. In the aftermath of the Reichstag fire, Hitler created a totalitarian single-party state led by the Nazis.
The Kuomintang (KMT) party in China launched a unification campaign against regional warlords and nominally unified China in the mid-1920s, but was soon embroiled in a civil war against its former Chinese communist allies.In 1931, an increasingly militaristic Japanese Empire, which had long sought influence in Chinaas the first step of what its government saw as the country's right to rule Asia, used the Mukden Incident as a pretext to launch an invasion of Manchuria and establish the puppet state of Manchukuo.
Too weak to resist Japan, China appealed to the League of Nations for help. Japan withdrew from the League of Nations after being condemned for its incursion into Manchuria. The two nations then fought several battles, in Shanghai, Rehe and Hebei, until the Tanggu Truce was signed in 1933. Thereafter, Chinese volunteer forces continued the resistance to Japanese aggression in Manchuria, and Chahar and Suiyuan.
Axis collapse, Allied victory (1944–45)
Yalta Conference held in February 1945, with Winston Churchill, Franklin D. Roosevelt and Joseph Stalin
On 16 December 1944, Germany attempted its last desperate measure for success on the Western Front by using most of its remaining reserves to launch a massive counter-offensive in the Ardennes to attempt to split the Western Allies, encircle large portions of Western Allied troops and capture their primary supply port at Antwerp to prompt a political settlement. By January, the offensive had been repulsed with no strategic objectives fulfilled. In Italy, the Western Allies remained stalemated at the German defensive line. In mid-January 1945, the Soviets and Poles attacked in Poland, pushing from the Vistula to the Oder river in Germany, and overran East Prussia. On 4 February, US, British, and Soviet leaders met for the Yalta Conference. They agreed on the occupation of post-war Germany, and on when the Soviet Union would join the war against Japan.
In February, the Soviets invaded Silesia and Pomerania, while Western Allies entered western Germany and closed to the Rhine river. By March, the Western Allies crossed the Rhine north and south of the Ruhr, encircling the German Army Group B, while the Soviets advanced to Vienna. In early April, the Western Allies finally pushed forward in Italy and swept across western Germany, while Soviet and Polish forces stormed Berlin in late April. The American and Soviet forces linked up on Elbe river on 25 April. On 30 April 1945, the Reichstag was captured, signalling the military defeat of the Third Reich.
Several changes in leadership occurred during this period. On 12 April, President Roosevelt died and was succeeded by Harry Truman. Benito Mussolini was killed by Italian partisans on 28 April. Two days later, Hitler committed suicide, and was succeeded by Grand Admiral Karl Dönitz.

German forces surrendered in Italy on 29 April. Total and unconditional surrender was signed on 7 May, to be effective by the end of 8 May.German Army Group Centre resisted in Prague until 11 May.
In the Pacific theatre, American forces accompanied by the forces of the Philippine Commonwealth advanced in the Philippines, clearing Leyte by the end of April 1945. They landed on Luzon in January 1945 and captured Manila in March following a battle which reduced the city to ruins. Fighting continued on Luzon, Mindanao, and other islands of the Philippines until the end of the war.On the night of 9–10 March, B-29 bombers of the US Army Air Forces struck Tokyo with incendiary bombs, which killed 100,000 people within a few hours. Over the next five months, American bombers firebombed 66 other Japanese cities, causing the destruction of untold numbers of buildings and the deaths of between 350,000–500,000 Japanese civilians.

In May 1945, Australian troops landed in Borneo, over-running the oilfields there. British, American, and Chinese forces defeated the Japanese in northern Burma in March, and the British pushed on to reach Rangoon by 3 May. Chinese forces started to counterattack in Battle of West Hunan that occurred between 6 April and 7 June 1945. American forces also moved towards Japan, taking Iwo Jima by March, and Okinawa by the end of June At the same time American bombers were destroying Japanese cities, American submarines cut off Japanese imports, drastically reducing Japan's ability to supply its overseas force.
On 11 July, Allied leaders met in Potsdam, Germany. They confirmed earlier agreements about Germany,and reiterated the demand for unconditional surrender of all Japanese forces by Japan, specifically stating that "the alternative for Japan is prompt and utter destruction". During this conference, the United Kingdom held its general election, and Clement Attlee replaced Churchill as Prime Minister.
As Japan continued to ignore the Potsdam terms issued to them on 27 July, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki in early August. Like the Japanese cities previously bombed by American airmen, the US and its allies justified the atomic bombings as military necessity to avoid invading the Japanese home islands which would cost the lives of between 250,000–500,000 Allied troops and millions of Japanese troops and civilians.Between the two bombings, the Soviets, pursuant to the Yalta agreement, invaded Japanese-held Manchuria, and quickly defeated the Kwantung Army, which was the largest Japanese fighting force.The Red Army also captured Sakhalin Island and the Kuril Islands. On 15 August 1945, Japan surrendered, with the surrender documents finally signed aboard the deck of the American battleship USS Missouri on 2 September 1945, ending the war
Aftermath

Post-war Soviet territorial expansion; resulted in Central European border changes, the creation of a Communist Bloc, and start of the Cold War
The Allies established occupation administrations in Austria and Germany. The former became a neutral state, non-aligned with any political bloc. The latter was divided into western and eastern occupation zones controlled by the Western Allies and the USSR, accordingly. A denazification program in Germany led to the prosecution of Nazi war criminals and the removal of ex-Nazis from power, although this policy moved towards amnesty and re-integration of ex-Nazis into West German society.
Germany lost a quarter of its pre-war (1937) territory. Among the eastern territories, Silesia, Neumark and most of Pomerania were taken over by Poland, East Prussia was divided between Poland and the USSR, followed by the expulsion of the 9 million Germans from these provinces, as well as the expulsion of 3 million Germans from the Sudetenland in Czechoslovakia to Germany. By the 1950s, every fifth West German was a refugee from the east. The Soviet Union also took over the Polish provinces east of the Curzon line, from which 2 million Poles were expelled;north-east Romania parts of eastern Finland,and the three Baltic states were also incorporated into the USSR.
In an effort to maintain peace,the Allies formed the United Nations, which officially came into existence on 24 October 1945, and adopted the Universal Declaration of Human Rights in 1948, as a common standard for all member nations. The great powers that were the victors of the war—the United States, Soviet Union, China, Britain, and France—formed the permanent members of the UN's Security Council.The five permanent members remain so to the present, although there have been two seat changes, between the Republic of China and the People's Republic of China in 1971, and between the Soviet Union and its successor state, the Russian Federation, following the dissolution of the Soviet Union. The alliance between the Western Allies and the Soviet Union had begun to deteriorate even before the war was over.
Germany had been de facto divided, and two independent states, the Federal Republic of Germany and the German Democratic Republicwere created within the borders of Allied and Soviet occupation zones, accordingly. The rest of Europe was also divided into Western and Soviet spheres of influence. Most eastern and central European countries fell into the Soviet sphere, which led to establishment of Communist-led regimes, with full or partial support of the Soviet occupation authorities. As a result, Poland, Hungary, East Germany,Czechoslovakia, Romania, and Albaniabecame Soviet satellite states. Communist Yugoslavia conducted a fully independent policy, causing tension with the USSR.
Post-war division of the world was formalised by two international military alliances, the United States-led NATO and the Soviet-led Warsaw Pact;the long period of political tensions and military competition between them, the Cold War, would be accompanied by an unprecedented arms race and proxy wars.
In Asia, the United States led the occupation of Japan and administrated Japan's former islands in the Western Pacific, while the Soviets annexed Sakhalin and the Kuril Islands.Korea, formerly under Japanese rule, was divided and occupied by the US in the South and the Soviet Union in the North between 1945 and 1948. Separate republics emerged on both sides of the 38th parallel in 1948, each claiming to be the legitimate government for all of Korea, which led ultimately to the Korean War.
In China, nationalist and communist forces resumed the civil war in June 1946. Communist forces were victorious and established the People's Republic of China on the mainland, while nationalist forces retreated to Taiwan in 194.In the Middle East, the Arab rejection of the United Nations Partition Plan for Palestine and the creation of Israel marked the escalation of the Arab-Israeli conflict. While European colonial powers attempted to retain some or all of their colonial empires, their losses of prestige and resources during the war rendered this unsuccessful, leading to decolonisation.
The global economy suffered heavily from the war, although participating nations were affected differently. The US emerged much richer than any other nation; it had a baby boom and by 1950 its gross domestic product per person was much higher than that of any of the other powers and it dominated the world economy.The UK and US pursued a policy of industrial disarmament in Western Germany in the years 1945–1948.Due to international trade interdependencies this led to European economic stagnation and delayed European recovery for several years
Recovery began with the mid-1948 currency reform in Western Germany, and was sped up by the liberalisation of European economic policy that the Marshall Plan (1948–1951) both directly and indirectly caused.The post-1948 West German recovery has been called the German economic miraclItaly also experienced an economic boom[303] and the French economy rebounded.By contrast, the United Kingdom was in a state of economic ruin,and although it received a quarter of the total Marshall Plan assistance, more than any other European country, continued relative economic decline for decades
The Soviet Union, despite enormous human and material losses, also experienced rapid increase in production in the immediate post-war era.[308] Japan experienced incredibly rapid economic growth, becoming one of the most powerful economies in the world by the 1980s. China returned to its pre-war industrial production by 1952.
