Answer given below.

Explanation:

The First World War fought in 1914 in Europe. European countries began to form alliances with other countries after the assassination of the heir of Austria-Hungary Archduke Franz Ferdinand. Imperialism, Militarism, and Nationalism were the root of the war.

Under the reign of Emperor William II, Germany acquired territories in the Far East. Germany also began to launch a large navy, challenged French control in Morocco, and build a railway line through Baghdad that frightened Britain rule in the Persian Gulf. Germany became the largest manufacturer in Europe.  

The Berlin Conference in 1885 supported the European powers in the colonization of Africa. The resources and wealth in Asia and Africa led to the arrival of several colonial powers that led to the emerging of colonies. It all began in the mid-1800s when Europe indulged in imperialism, which resulted in conquest, military invasions, and colonization in Africa and Asia. European powers started colonizing for three factors- social, economic, and political.

The border conflict over the region of Alsace and Lorraine began the rivalry between France and Germany.

The Balkan region saw the rise of nationalism as the Ottoman Empire started to lose its power. The Balkan issue became one of the causes for the First World War as the European powers - Russia, Germany, Britain, and Austria, wanted to control the area.
