The expansion of European nations as empires (also known as imperialism) can be seen as a key cause of World War I, because as countries like Britain and France expanded their empires, it resulted in increased tensions among European countries.
Unlike the second world war, the bloodbath of 1914-18 was not a just war. It was a savage industrial slaughter perpetrated by a gang of predatory imperial powers, locked in a deadly struggle to capture and carve up territories, markets and resources.
Hope this helps!
