Austria blamed Serbia - it's excuse for war was found. Serbia was a threat to Austria as the most powerful
country in the Balkans.
Germany's 'Blank Cheque'
With Germany offering unconditional support for Austria (blank cheque), it encouraged
Austria to act more outrageous than it would have done alone as they knew Germany
would be there to back them up.
Long Term
Nationalism
The belief that your country is superior to all other counties with the belief you could 'take them on' if
necessary. This leads nations to become assertive and aggressive.
Imperialism
The desire to conquer colonies, especially in Africa. This brought the powers into conflict - Germany wanted an empire.
France and Britain already had empires. Germany believed that they were 'entitled' and deserved an empire the size of
Britain's.
Alliances
In 1882, Germany, Austria-Hungary and Italy formed the Triple Alliance. This alarmed, France, Britain and
Russia. By 1907, they had all joined the Triple Entente. Europe was divided into two armed camps, to help
each other if there was a war. It meant other countries felt inclined to protect their alliance.
Militarism (Arms Race)
The attempt to build up a strong army and navy gave nations the means and will to make war. It started a competition
and countries became threats.
