France wanted Alsace Lorraine back from Germany who was lost in 1871 Franco-Prussian war.
The use of Nationalism gave nations false hope and aggressive to win the war.
In 1905, Kaiser visited Morocco in North Africa, where Germany was building up its own Empire. At the conference Kaiser was humiliated, this made him fill with rage because he wanted to be seen as Major power in Africa.
Instead, he was treated as if he had no right in speaking at the conference that was made global news. Britain feared that Kaiser wanted to set up a naval base in Agadir.
By Germany, Britain and France participating in the naval and army race, they were able to build their navies to their top standard, this lead to the next stage which was Alliances, also their navy’s strength, significance in the war and how it would help them win the war. In 1914 the six most powerful countries in Europe divided into two opposing Alliances (sides/teams).
The Triple Alliance consisted of Germany, Austria-Hungary and Italy which was formed in 1882.
The Kaiser felt he needed a bigger navy than Britain to protect its country.
While Britain and Germany built up their navies, the major powers on mainland Europe were also building up their armies.
This is because big armies become potential threats to other countries, other countries started forcing alliances in order to secure land.
Imperialism was a cause because building an empire needs manpower such as an army and a navy to conquer and keep the land that they colonised.
