###Input: Bolshevik leaders had effectively reestablished a polity with roughly the same extent as that empire by 1921, however with an internationalist ideology: Lenin in particular asserted the right to limited self-determination for national minorities within the new territory. Beginning in 1923, the policy of "Indigenization" [korenizatsiia] was intended to support non-Russians develop their national cultures within a socialist framework. Never formally revoked, it stopped being implemented after 1932. After World War II, the Soviet Union installed socialist regimes modeled on those it had installed in 1919–20 in the old Tsarist Empire in areas its forces occupied in Eastern Europe. The Soviet Union and the People’s Republic of China supported post–World War II communist movements in foreign nations and colonies to advance their own interests, but were not always successful.

Trotsky, and others, believed that the revolution could only succeed in Russia as part of a world revolution. Lenin wrote extensively on the matter and famously declared that Imperialism was the highest stage of capitalism. However, after Lenin's death, Joseph Stalin established 'socialism in one country' for the Soviet Union, creating the model for subsequent inward looking Stalinist states and purging the early Internationalist elements. The internationalist tendencies of the early revolution would be abandoned until they returned in the framework of a client state in competition with the Americans during the Cold War. With the beginning of the new era, the after Stalin period called the "thaw", in the late 1950s, the new political leader Nikita Khrushchev put even more pressure on the Soviet-American relations starting a new wave of anti-imperialist propaganda. In his speech on the UN conference in 1960, he announced the continuation of the war on imperialism, stating that soon the people of different countries will come together and overthrow their imperialist leaders. Although the Soviet Union declared itself anti-imperialist, critics argue that it exhibited tendencies common to historic empires. Some scholars hold that the Soviet Union was a hybrid entity containing elements common to both multinational empires and nation states. It has also been argued that the USSR practiced colonialism as did other imperial powers and was carrying on the old Russian tradition of expansion and control. Mao Zedong once argued that the Soviet Union had itself become an imperialist power while maintaining a socialist façade. Moreover, the ideas of imperialism were widely spread in action on the higher levels of government. Non Russian Marxists within the Russian Federation and later the USSR, like Sultan Galiev and Vasyl Shakhrai, considered the Soviet Regime a renewed version of the Russian imperialism and colonialism.

The First British Empire was based on mercantilism, and involved colonies and holdings primarily in North America, the Caribbean, and India. Its growth was reversed by the loss of the American colonies in 1776. Britain made compensating gains in India, Australia, and in constructing an informal economic empire through control of trade and finance in Latin America after the independence of Spanish and Portuguese colonies about 1820. By the 1840s, Britain had adopted a highly successful policy of free trade that gave it dominance in the trade of much of the world. After losing its first Empire to the Americans, Britain then turned its attention towards Asia, Africa, and the Pacific. Following the defeat of Napoleonic France in 1815, Britain enjoyed a century of almost unchallenged dominance and expanded its imperial holdings around the globe. Increasing degrees of internal autonomy were granted to its white settler colonies in the 20th century.

A resurgence came in the late 19th century, with the Scramble for Africa and major additions in Asia and the Middle East. The British spirit of imperialism was expressed by Joseph Chamberlain and Lord Rosebury, and implemented in Africa by Cecil Rhodes. The pseudo-sciences of Social Darwinism and theories of race formed an ideological underpinning during this time. Other influential spokesmen included Lord Cromer, Lord Curzon, General Kitchner, Lord Milner, and the writer Rudyard Kipling. The British Empire was the largest Empire that the world has ever seen both in terms of landmass and population. Its power, both military and economic, remained unmatched.

The early United States expressed its opposition to Imperialism, at least in a form distinct from its own Manifest Destiny, through policies such as the Monroe Doctrine. However, beginning in the late 19th and early 20th century, policies such as Theodore Roosevelt’s interventionism in Central America and Woodrow Wilson’s mission to "make the world safe for democracy" changed all this. They were often backed by military force, but were more often affected from behind the scenes. This is consistent with the general notion of hegemony and imperium of historical empires. In 1898, Americans who opposed imperialism created the Anti-Imperialist League to oppose the US annexation of the Philippines and Cuba. One year later, a war erupted in the Philippines causing business, labor and government leaders in the US to condemn America's occupation in the Philippines as they also denounced them for causing the deaths of many Filipinos. American foreign policy was denounced as a "racket" by Smedley Butler, an American general. He said, "Looking back on it, I might have given Al Capone a few hints. The best he could do was to operate his racket in three districts. I operated on three continents".
