Nationalism & Imperialism• Nationalism is a feeling of intense pride in one’s
homeland. Nationalists emphasized their homeland’s culture and interests above other countries and they were willing to go to war to expand their nation at the expense of others.
• Self-determination is another basic idea of nationalism. Self-determination is the idea that people who share a national identity should have their own country and government.
• Imperialism: Great Britain, Germany and France needed foreign markets after the increase in manufacturing caused by the Industrial Revolution
