The causes of World War I can be summarized by the acronym MAIN: militarism, alliances, imperialism, and nationalism
Militarism is the desire of a state to develop and maintain a powerful military to advance their interests aggressively
Britain and Germany heavily invested in bulking up their militaries prior to World War I
Alliances were formed between nations for mutual self-defense, leading to complex relationships
Imperialism involved bringing other countries under political or economic dominion, leading to bitter rivalries
Nationalism, a strong identification with one's nation to the exclusion of others, added to the tensions
The assassination of Archduke Franz Ferdinand of Austria-Hungary in 1914 sparked World War I
The assassination led to a chain of declarations of war among European powers, escalating the conflict
At the beginning of the 20th century, the West dominated the global balance of power, but by the end of the century, many Maritime and land-based Empires fell apart, giving rise to new States
Four key illustrations of state power shifting after 1900:
Decline of the Ottoman Empire, leading to the emergence of reform-minded groups like the Young Ottomans and The Young Turks
Russian Empire's progress in industrialization under Alexander II and Nicholas II, leading to the Russian Revolution of 1905 and later the successful Russian Revolution of 1917 led by Lenin and the Bolsheviks
China's struggles, including the Tai Ping Rebellion, the Opium Wars, the Sino-Japanese war, and the Boxer Rebellion, leading to the end of Imperial rule under Sun Yat-sen and the emergence of a communist state under Mao Zedong
Mexican Revolution against dictator Porfirio Diaz, resulting in a decade of Civil War and the emergence of a republic with a newly drafted Constitution in 1917
Massacre of Amritsar in 1919 radicalized many Indians, leading to a desire for a free and independent India
