At the start of the 20th century, the Western powers—Britain, France, the Netherlands—dominated global politics, largely due to their imperial holdings and industrialized economies. Their control over global trade routes, colonial resources, and military power allowed them to exert significant influence worldwide.
Meanwhile, older land-based empires—notably the Ottoman, Russian, Austro-Hungarian, and Qing empires—were declining. They struggled to modernize in the face of both internal weakness and external imperial pressure. By contrast, Japan had successfully industrialized after the Meiji Restoration and emerged as a rising global power, while the United States gained overseas territories and rapidly increased its economic and military presence.
The early 20th century thus witnessed a dramatic reconfiguration of global power: empires fell, new states rose, and Western dominance began to face resistance from within and beyond its colonial borders.
The Ottoman Empire, once a powerful Islamic empire, had been losing territory and political strength since the 18th century. In the 19th century, Ottoman leaders initiated the Tanzimat Reforms, aimed at modernizing the legal, military, and educational systems.
⭐
While these reforms modernized parts of the empire, they failed to halt its overall decline. Resistance from conservative factions, rising nationalism among ethnic minorities, and continued economic weakness undermined efforts at reform.
In 1908, the Young Turks—a group of military officers and intellectuals—staged a coup and implemented further constitutional reforms. However, the empire was soon drawn into World War I, and its defeat led to its formal collapse.
The Qing Dynasty faced immense pressure in the 19th century from both foreign imperialism and domestic unrest. Repeated defeats in wars (e.g., the Opium Wars) and the imposition of unequal treaties weakened the state.
Meanwhile, massive uprisings such as the Taiping Rebellion (1850–1864) and the Boxer Rebellion (1899–1901) revealed growing dissatisfaction among the population.
⭐
In 1911, the Xinhai Revolution led to the fall of the Qing and the establishment of the Republic of China, ending over 2,000 years of imperial rule.
The Russian Empire industrialized late compared to Western Europe. While the state built railroads (like the Trans-Siberian Railway) and invested in heavy industry, deep social and economic inequality persisted.
Continued hardship, World War I losses, and mass discontent culminated in the Russian Revolutions of 1917:
In 1922, the Union of Soviet Socialist Republics (USSR) was established, representing a complete transformation of political power and ideology.

⭐ Change: While these empires collapsed, many of their successor states retained old elites or struggled to unify diverse populations under new governments.
While much focus is placed on Eurasian empires, Latin America also experienced upheaval in the early 20th century. The Mexican Revolution (1910–1920) arose from dissatisfaction with the dictatorship of Porfirio Díaz.
Key revolutionary figures included Emiliano Zapata (agrarian reformer) and Pancho Villa (northern guerrilla leader). The revolution ultimately led to:
The early 20th century marked a critical turning point in global history. Old empires crumbled under the weight of internal problems and external pressures, giving rise to new states and ideologies. In their place emerged revolutionary governments, republics, and, in Russia’s case, a communist superpower.
These power shifts fundamentally altered global geopolitics and set the stage for the world wars, the Cold War, and independence movements across the colonial world.
