William Ewart Gladstone was the dominant figure of Victorian liberalism, serving as Prime Minister four times and embodying 19th-century progressivism's faith in moral improvement, free trade, and extending liberty. His rivalry with Disraeli defined an era; his commitment to Irish Home Rule split his party.
Gladstone began as a Conservative but evolved toward liberalism, championing free trade, expanded suffrage, Irish land reform, and education. His Midlothian Campaign pioneered modern electioneering. He believed in minimal government but also moral government—foreign policy should follow ethical principles, not just national interest.
Gladstone's crusade for Irish Home Rule consumed his final decades. Convinced that justice required Irish self-government, he split the Liberal Party and failed to pass Home Rule. His moral earnestness could seem self-righteous; Disraeli complained he didn't mind Gladstone having an ace up his sleeve, only his pretense that God put it there. Yet Gladstone's high-minded liberalism—peace, retrenchment, and reform—defined progressive politics for generations.
