Invasion in the context of "Nuremberg trials"

A temporary capital or a provisional capital is a city or town chosen by a government as an interim base of operations due to some difficulty in retaining or establishing control of a different metropolitan area. The most common circumstances leading to this are either a civil war, where control of the capital is contested, or during an invasion, where the designated capital is taken or threatened.

By definition, a temporary capital is located somewhere on the country's territory, as opposed to a capital-in-exile located on the territory of a different country. However, a country's capital may move in and out of exile over the course of a conflict.

Human migration is the movement of people from one place to another, with intentions of settling, permanently or temporarily, at a new location (geographic region). The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is the dominant form of human migration globally.

Migration is often associated with better human capital at both individual and household level, and with better access to migration networks, facilitating a possible second move. It has a high potential to improve human development, and some studies confirm that migration is the most direct route out of poverty. Age is also important for both work and non-work migration. People may migrate as individuals, in family units or in large groups. There are four major forms of migration: invasion, conquest, colonization and emigration/immigration.

A buffer state is a country geographically lying between two rival or potentially hostile great powers. Its existence can sometimes be thought to prevent conflict between them. A buffer state is sometimes a mutually agreed upon area lying between two greater powers, which is demilitarised in the sense of not hosting the armed forces of either power (though it will usually have its own military forces). The invasion of a buffer state by one of the powers surrounding it will often result in war between the powers.

Buffer states, when authentically independent, typically pursue a neutralist foreign policy, which distinguishes them from satellite states. The concept of buffer states is part of a theory of the balance of power that entered European strategic and diplomatic thinking in the 18th century. After the First World War, notable examples of buffer states were Poland and Czechoslovakia, situated between major powers such as Germany and the Soviet Union. Lebanon is another significant example, positioned between Syria and Israel, thereby experiencing challenges as a result.

A fortification (also called a fort, fortress, fastness, or stronghold) is a military construction designed for the defense of territories in warfare, and is used to establish rule in a region during peacetime. The term is derived from Latin fortis ("strong") and facere ("to make").

From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley Civilization were the first small cities to be fortified. In ancient Greece, large cyclopean stone walls fitted without mortar had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek phrourion was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted as a border guard rather than a real strongpoint to watch and maintain the border.

In Marxist philosophy, cultural hegemony is the dominance of a culturally diverse society by the ruling class who shape the culture of that society—the beliefs and explanations, perceptions, values, and mores—so that the worldview of the ruling class becomes the accepted cultural norm. As the universal dominant ideology, the ruling-class worldview misrepresents the social, political, and economic status quo as natural and inevitable, and that it perpetuates social conditions that benefit every social class, rather than as artificial social constructs that benefit only the ruling class.When the social control is carried out by another society, it is known as cultural imperialism.

In philosophy and in sociology, the denotations and the connotations of term cultural hegemony derive from the Ancient Greek word hegemonia (ἡγεμονία), which indicates the leadership and the régime of the hegemon. In political science, hegemony is the geopolitical dominance exercised by an empire, the hegemon (leader state) that rules the subordinate states of the empire by the threat of intervention, an implied means of power, rather than by threat of direct rule—military invasion, occupation, and territorial annexation.

Interventionism, in international politics, is the interference of a state or group of states into the domestic affairs of another state for the purposes of coercing that state to do something or refrain from doing something. The intervention can be conducted through military force or economic coercion. A different term, economic interventionism, refers to government interventions into markets at home.

Military intervention, which is a common element of interventionism, has been defined by Martha Finnemore in the context of international relations as "the deployment of military personnel across recognized boundaries for the purpose of determining the political authority structure in the target state". Interventions may be solely focused on altering political authority structures, or may be conducted for humanitarian purposes, or for debt collection. The 1933 Montevideo Convention on the Rights and Duties of States provides that "no state has the right to intervene in the internal or external affairs of another." The General Assembly of the United Nations has condemned (with one abstaining and no dissenting vote) "armed intervention and all other forms of interference or attempted threats against the personality of the State or against its political, economic and cultural elements."

The Shanhai Pass (simplified Chinese: 山海关; traditional Chinese: 山海關; pinyin: Shānhǎi Guān; lit. 'Mountain Sea Pass') is a major fortified gateway at the eastern end of the Great Wall of China and one of its most crucial fortifications, as the pass commands the narrowest choke point in the strategic Liaoxi Corridor, an elongated coastal plain between the Yan Mountains foothills and the Bohai Sea, which is the only easily traversable landway between North and Northeast China. It is located in present-day Shanhaiguan District, Qinhuangdao, Hebei province, on the east bank of the Shi River, with defensive walls stretching from the Yan Mountains all the way to the shores of the Liaodong Bay.

Throughout Chinese history, garrisons around the pass served as frontline defensive outposts against raids and incursions into the North China Plain by various non-Sinitic ethnic groups from the Northeast (also known as Manchuria since the 19th century), including the Dongyi, Donghu (Xianbei and Wuhuan), Khitan and Jurchen (Manchus). The current Shanhai Pass was built during the early Ming dynasty as the easternmost fortification of the Ming Great Wall, and was extensively reinforced after Yongle Emperor moved the capital from Nanjing to Beijing following the Jingnan campaign, making it the most important defensive barrier in all of China, as it shielded the heartland region around the imperial capital. The pass' strategic location dictated that without mounting a costly direct siege, the only way an invading army can get past the pass' defense was to circumvent it around the north through a few treacherously narrow mountain passes deep within the Yan Mountains, which would make it very difficult to maintain supply lines and thus any sizeable invasions. This defensive significance therefore earned the pass the famous nickname "Greatest Pass Under Heaven" (天下第一关).
