In war, an open city is a settlement which has announced it has abandoned all defensive efforts, generally in the event of the imminent capture of the city to avoid destruction. Once a city has declared itself open, the opposing military will be expected under international law to peacefully occupy the city rather than destroy it. According to Protocol I of the Geneva Conventions, it is forbidden for the attacking party to "attack, by any means whatsoever, non-defended localities". [1] The intent is to protect the city's civilians and cultural landmarks from a battle which may be futile.
Attacking forces do not always respect the declaration of an open city. Defensive forces will occasionally use the designation as a political tactic as well. [2] In some cases, the declaration of a city to be open is made by a side on the verge of defeat and surrender; in other cases, those making such a declaration are willing and able to fight on, but prefer that the specific city be spared. Often, resistance movements will be active in open cities, straining the temperate conduct of the occupying forces.
Numerous cities were declared open cities during World War II:
In 1977, a far-left group in Japan—called the "National Open City Declaration Movement Network"—began organizing activists to make cities preemptively declare themselves "defenseless" under the Geneva Convention, so that in the event of war, they would be legally forced to welcome any invasion. [16] This was rejected by nearly all of Japan's political parties and the ruling government as inherently absurd, since Japan was not in a war, and in the event of war such a decision would have to be approved by the national government. [17] However, the Social Democratic Party—which was the junior party of the ruling coalition from 1994 to 1996—supported it. [18] [ when? ]
Nevertheless, four wards of Tokyo and Kagoshima City, Japan's southernmost port, among many other cities considered[ when? ] legislation to be declared "open cities". [19]
World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II was the deadliest conflict in history, resulting in 70 to 85 million deaths, more than half of which were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.
The Axis powers, originally called the Rome–Berlin Axis and also Rome–Berlin–Tokyo Axis, was a military coalition that initiated World War II and fought against the Allies. Its principal members were Nazi Germany, Fascist Italy and the Empire of Japan. The Axis were united in their far-right positions and general opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion.
The European theatre of World War II was one of the two main theatres of combat during World War II, taking place from September 1939 to May 1945. The Allied powers fought the Axis powers on both sides of the continent in the Western and Eastern fronts. There was also conflict in the Scandinavian, Mediterranean and Balkan regions. It was an intense conflict that led to at least 39 million deaths and a dramatic change in the balance of power in the continent.
The South-East Asian Theatre of World War II consisted of the campaigns of the Pacific War in the Philippines, Thailand, Indonesia, Indochina, Burma, India, Malaya, and Singapore between 1941 and 1945.
Almost every country in the world participated in World War II. Most were neutral at the beginning, but only a relative few nations remained neutral to the end. The Second World War pitted two alliances against each other, the Axis powers and the Allied powers. It is estimated that 74 million people died, with estimates ranging from 40 million to 90 million dead. The main Axis powers were Nazi Germany, the Empire of Japan, and the Kingdom of Italy; while the United Kingdom, the United States, the Soviet Union and China were the "Big Four" Allied powers.
This article is concerned with the events that preceded World War II in Asia.
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members by the end of 1941 were the "Big Four" – the United Kingdom, United States, Soviet Union, and China.
The history of Bulgaria during World War II encompasses an initial period of neutrality until 1 March 1941, a period of alliance with the Axis Powers until 8 September 1944, and a period of alignment with the Allies in the final year of the war. With German consent, Bulgarian military forces occupied parts of the Kingdoms of Greece and Yugoslavia which Bulgarian irredentism claimed on the basis of the 1878 Treaty of San Stefano. Bulgaria resisted Axis pressure to join the war against the Soviet Union, which began on 22 June 1941, but did declare war on Britain and the United States on 13 December 1941. The Red Army entered Bulgaria on 8 September 1944; Bulgaria declared war on Germany the next day.
The neutral powers were countries that remained neutral during World War II. Some of these countries had large colonies abroad or had great economic power. Spain had just been through its civil war, which ended on 1 April 1939 —a war that involved several countries that subsequently participated in World War II.
The government of the United Kingdom declared war on the Empire of Japan on 8 December 1941, following the Japanese attacks on British Malaya, Singapore, and Hong Kong on the previous day as well as in response to the bombing of the US fleet at Pearl Harbor.

Vatican City pursued a policy of neutrality during World War II under the leadership of Pope Pius XII. Although the city of Rome was occupied by Germany from September 1943 and the Allies from June 1944, Vatican City itself was not occupied. The Vatican organised extensive humanitarian aid throughout the duration of the conflict.
