Explanation:

Imperialism is a cause because European countries competed in claiming lands in different continents.  France and England were most successful, especially in the lands they colonized in Africa.  Germany was especially jealous of England's and France’s land claims.

Effect- On August 4, 1914, German forces crossed this edge into Belgium. At the early fight of world war one, the Germans attacked the hard fortified city of Liege, utilizing the most potent weapons in their arsenal—enormous siege cannons—to capture this city by August 15. Giving death and death in their aftermath, including the shot of civilians and the murder of the Belgian priest, whom they accused of instigating civil resistance, the Germans gained through Belgium towards France.
