Key themes to remember
Industrialization began in Britain and spread unevenly. Coal, iron, and capital advantages let Britain industrialize first; Belgium, France, and Germany followed at different paces.
New ideologies responded to industrial inequality. Classical liberalism defended the new capitalist order, while Marxism, utopian socialism, and trade unions challenged it.
Social structures were reshaped, not just the economy. Urbanization, child labor, and new gender roles transformed daily life for both the working and middle classes.
Reform emerged gradually, not all at once. The Factory Acts and Chartism show government and workers slowly responding to industrialization's social costs.
Common exam traps
Don't confuse Marxism with all forms of socialism. Marx called for revolutionary class struggle, while utopian socialists proposed peaceful, cooperative communities.
The Second Industrial Revolution is distinct from the first. The first centered on textiles, coal, and iron; the second (later 19th century) added steel, chemicals, and electricity.
Laissez-faire liberalism and socialism are opposing responses, not the same thing. Liberals wanted minimal government interference; socialists wanted greater collective or state control.
Don't overstate immediate reform. Factory Acts and suffrage expansion came gradually and incompletely — don't imply industrial workers won full rights right away.
Social Darwinism is a justification, not a cause, of inequality. Be ready to explain how it was used to rationalize existing class divisions rather than create them.
