Expansionism

Expansionism refers to states obtaining greater territory through military empire-building or colonialism.
In the classical age of conquest moral justification for territorial expansion at the direct expense of another established polity (who often faced displacement, subjugation, slavery, rape and execution) was often as unapologetic as "because we can" treading on the philosophical grounds of might makes right.
As political conceptions of the nation state evolved, especially in reference to the inherent rights of the governed, more complex justifications arose. State-collapse anarchy, reunification or pan-nationalism are sometimes used to justify and legitimize expansionism when the explicit goal is to reconquer territories that have been lost or to take over ancestral lands.
Lacking a viable historical claim of this nature, would-be expansionists may instead promote ideologies of promised lands (such as manifest destiny or a religious destiny in the form of a Promised Land), perhaps tinged with a self-interested pragmatism that targeted lands will eventually belong to the potential invader anyway.
Theories
Ibn Khaldun wrote that newly established dynasties, because they have social cohesion or Asabiyyah, are able to seek "expansion to the limit."
The Soviet economist Nikolai Kondratiev theorized that capitalism advances in 50-year expansion/stagnation cycles, driven by technological innovation. The UK, Germany, the US, Japan and now China have been at the forefront of successive waves.
Crane Brinton in The Anatomy of Revolution saw the revolution as a driver of expansionism in, for example, Stalinist Russia, the United States and the Napoleonic Empire.
Christopher Booker believed that wishful thinking can generate a "dream phase" of expansionism such as in the European Union, which is short-lived and unreliable.
According to a 2023 study, important historical instances of territorial expansion have frequently happened because actors on the periphery of a state have acted without authorization from their superiors at the center of the state. Leaders subsequently find it difficult to withdraw from the newly captured areas due to "sunk costs, domestic political pressure, and national honor."
Examples
Every part of the world has experienced expansionism. The religious imperialism and colonialism of Islam started with the early Muslim conquests, was followed by the religious Caliphate expansionisms, and ended with the Partition of the Ottoman Empire. In the 15th and 16th centuries, the Ottoman Empire entered a period of expansion. The Ottomans ended the Eastern Roman Empire with the conquest of Constantinople in 1453 by Mehmed the Conqueror.
The militarist and nationalistic reign of Russian Czar Nicholas I (1825–1855) led to wars of conquest against Persia (1826–1828) and Turkey (1828–1829). Various rebel tribes in the Caucasus region were crushed. A Polish revolt in 1830 was ruthlessly crushed. Russian troops in 1848 crossed into Austria-Hungary to put down the Hungarian Revolt. Russification policies were implemented to weaken minority ethnic groups. Pan-Slavist solidarity led to further war with Turkey (the sick man of Europe) in 1853 provoked Britain and France into invading Crimea.
In Italy, Benito Mussolini sought to create a New Roman Empire, based around the Mediterranean. Italy invaded Ethiopia as early as 1935, Albania in early 1938, and later Greece. Spazio vitale ("living space") was the territorial expansionist concept of Italian Fascism. It was analogous to Nazi Germany's concept of Lebensraum and the United States' concept of "Manifest Destiny". Fascist ideologist Giuseppe Bottai likened this historic mission to the deeds of the ancient Romans.
After 1937, Nazi Germany under Hitler laid claim to Sudetenland, unification (Anschluss) with Austria in 1938 and the occupation of the whole of the Czech lands the following year. After war broke out, Hitler and Stalin divided Poland between Germany and the Soviet Union. In a Drang nach Osten aimed at achieving Lebensraum for the German people, Germany invaded the Soviet Union in 1941.
Expansionist nationalism is an aggressive and radical form of nationalism that incorporates autonomous patriotic sentiments with a belief in expansionism. The term was coined during the late 19th century as European powers indulged in the Scramble for Africa, but it has been most associated with militarist governments during the 20th century including Fascist Italy, Nazi Germany, the Japanese Empire, and the Balkans countries of Albania (Greater Albania), Bulgaria (Greater Bulgaria), Croatia (Greater Croatia), Hungary (Greater Hungary), Romania (Greater Romania) and Serbia (Greater Serbia).
In American politics after the War of 1812, Manifest Destiny was the ideological movement during America's expansion West. The movement incorporated expansionist nationalism with continentalism, with the Mexican War in 1846–1848 being attributed to it. Despite championing American settlers and traders as the people whom the government's military would be aiding, the Bent, St. Vrain and Company stated to be the most influential Indian trading company prior to the Mexican War, underwent a decline because of the and of traffic from American settlers by Beyreis. The company also lost the partner Charles Bent on January 19, 1847, to a riot caused by the Mexican War. Many in the Cheyennes, Comanches, Kiowas, and Pawnees tribes died from smallpox in 1839–1840, measles and whooping cough in 1845, and cholera in 1849, which had been brought by American settlers. The buffalo herds, sparse grasses, and rare waters were also depleted following the war as increased traffic by settlers moving to California during the Gold Rush.
21st century
China
The People's Republic of China is accused of expansionism through its operations and claims in the South China Sea, which are concurrently claimed by Vietnam.
Israel
Israel was established on reacquired lands under international law and a manifest of original ownership on May 14, 1948, after the end of World War II and the Holocaust. Its government has occupied the West Bank, the Gaza Strip, the Golan Heights, and the Sinai Peninsula since the Six-Day War, although the Sinai was later returned to Egypt in 1982 and Israel disengaged from the Gaza Strip in 2005.
Iran
Iran, the largest Shi'ite state, has extended its influence across the entire Middle East, including Iraq, Lebanon, Syria, Yemen and Afghanistan by arming local militias.
Russia
Russia under Vladimir Putin has had an aggressive posture since 2008, especially since 2014. Events associated with Russia are the 2008 Russo-Georgian War and Russia's occupation of South Ossetia and Abkhazia; the Russo-Ukrainian War, which began in 2014 with the Annexation of Crimea and the war in Donbas and escalated into the ongoing full-scale Russian invasion of Ukraine in 2022; and the military intervention in Syria.
Turkey
Turkey's foreign policy is characterized, especially since 2010s by an aggressive expansionism, irredentism and interventionism in the Eastern Mediterranean and the neighboring Cyprus, Greece, Iraq, Syria, as well as in Africa, including Libya, and Nagorno-Karabakh. Turkey has occupied foreign territories and stationed troops in them, following the 1974 Turkish invasion of Cyprus, the Turkish occupation of northern Syria since 2016 and the Turkish presence in northern Iraq since 2018.
United States
The US retains military bases in some of the sovereign countries that it once occupied on a notionally-voluntary basis, including in Germany, Italy, Japan, Greenland, Iceland, Iraq, and formerly in Afghanistan. Guantanamo Bay Naval Base is retained despite the protests of the Cuban government, and the US has military bases in various other countries with which it has allied.
Ideologies
In the 19th century, theories of racial unity evolved such as Pan-Germanism, Pan-Slavism, and Pan-Turkism and the related Turanism. In each case, the dominant nation (respectively, Prussia; the Russian Empire; and the Ottoman Empire, especially under Enver Pasha) used those theories to legitimise their expansionist policies.
American ideology
In terms of Ideological reasons for American expansion, this goes back to the 19th century when Frederick Turner produced his Frontier Thesis which made the case for American expansionism on the US continent and that this turning point marked the beginning of a new epoch. The case for expansionism was made under the umbrella of advances in the American economy and democracy. Furthermore, this was aided at the latter end of the 19th century by the belief of Anglo Saxon and subsequent American superiority. This was exacerbated by a recession for the first time in 20 years and the Americans believed that they could unload their goods on to people because they had a God given right to do so. Their economic intentions were also supplemented by the fact that the Anglo Saxon race believed that they were simply better at governing a nation. Furthermore, there was also a belief that white people were simply superior. This racial superiority complex meant that some believed they had a right to enact their beliefs upon people who did not agree, such as Cuba, Guam and the Philippines.
Pan Americanism was a driver of governmental actors in the period, as the Harrison administration attempted to push through Pan American and tariff policies through the house and senate, however, their efforts were to no avail, but this showed that Pan Americanism was a driver in the efforts of the government for American expansion.
Further expansion came off the American continent, in the Philippines, at the turn of the century which was arguably driven by a paternalistic United States as McKinley’s objectives, he declared in mid-1899, were fourfold: “Peace first, then a government of law and order honestly administered, full security to life, property, and occupation under the Stars and Stripes.” However, the Philippines government was dictated by the Americans and ordinary Filipino people were not afforded the same privileges as the Americans that had been sent there.
It has also been posited that American leaders were pressured under traditional gender roles, which in turn made expansionism more likely. By the end of the 19th century President McKinley had been accustomed to being evaluated in terms of his manliness. This also played in to the fact that in the late nineteenth century, men saw supporting the military as the ultimate test of being a man. As a result, expansionism was a way of projecting manliness onto the electorate and in to society.
In popular culture
George Orwell's satirical novel Animal Farm is a fictional depiction, based on Stalin's Soviet Union, of a new elite seizing power, establishing new rules and hierarchies, and expanding economically while they compromise their ideals.
Robert Erskine Childers's novel The Riddle of the Sands portrays the threatening nature of the German Empire.
Elspeth Huxley's novel Red Strangers shows the effects on local culture of colonial expansion into Sub-Saharan Africa.
