Consequences of Industrialization (1750-1900)

Industrial states justified overseas expansion on economic, strategic, and ideological grounds. Factories needed raw materials such as cotton, rubber, and palm oil, along with markets and coaling stations on routes like the Suez Canal. Social Darwinists, following Herbert Spencer, claimed that stronger nations were destined to rule weaker ones. Missionaries and writers framed conquest as a civilizing duty, an idea captured in Kipling's poem The White Man's Burden.

European powers, Japan, and the United States expanded aggressively after 1870. The Berlin Conference of 1884 and 1885 set the rules for claiming African territory, including effective occupation, though the partition itself came through separate treaties and campaigns; Leopold II ran the Congo Free State as personal property. Britain defeated Qing China in the Opium Wars and took direct control of India after the 1857 rebellion. France seized Indochina, and the United States annexed the Philippines in 1898.

Colonized peoples resisted through rebellion, warfare, and religious movements. Indian soldiers rose against the East India Company in 1857, and the Boxer Rebellion attacked foreigners and Chinese Christians before an international force crushed it in 1900. Zulu forces destroyed a British column at Isandlwana in 1879, and Ethiopia under Menelik II defeated an Italian invasion at Adwa in 1896. Among the Lakota, the Ghost Dance expressed hopes of renewal and ended in the killings at Wounded Knee in 1890.

Imperial economies pushed colonies toward exporting a narrow range of commodities. Cotton from Egypt and India, rubber from the Congo and the Amazon, sugar from Cuba and Java, and palm oil from West Africa moved along commodity chains that ended in European and American factories. Railroads and ports were built to carry goods outward rather than to link colonial regions to one another. Land devoted to cash crops reduced food production and left export regions exposed to swings in world prices.

Powerful states extracted economic advantage without formal conquest. The Treaty of Nanjing in 1842 opened Chinese ports and granted extraterritoriality, and later agreements carved China into spheres of influence. Commodore Perry forced Japan open to foreign trade in 1853 on unequal terms, while European creditors ran the Ottoman Public Debt Administration after 1881. British capital dominated Argentine railroads, and firms such as the United Fruit Company shaped politics in Central America.

Migration surged as industrialization and imperialism reordered labor markets. Famine in Ireland, land shortages in southern Italy and China, and demand for workers in the Americas and Australia set powerful push and pull factors in motion. After Britain abolished slavery, planters recruited indentured laborers from India and China for sugar estates in Trinidad, Mauritius, Fiji, and Natal. Steamships and railroads made these journeys cheaper, and many migrants were young men who sent money home.

Migration reshaped societies at both ends of the journey. Migrants built ethnic enclaves such as Chinatowns in San Francisco and Indian communities in Natal and Trinidad, carrying languages, foods, and religions into new regions. Their arrival provoked nativist backlash, including the United States Chinese Exclusion Act of 1882 and restrictive Australian immigration laws. In sending regions, the departure of young men left women managing households and farms, while remittances supported families left behind.

Imperial expansion between 1750 and 1900 grew out of industrial demand for raw materials and markets, new military and medical technologies, and ideologies that ranked peoples by race. Its effects were uneven: colonies were tied to export economies, borders were drawn to suit conquerors, and millions migrated as laborers. Resistance ran from revolt in India and China to Ethiopia's victory at Adwa in 1896. The dependence and contested boundaries created then shaped conflicts long after 1900.
