Answer:
Step-by-step explanation:
cause: the assassination of Austria's Archduke Franz Ferdinand
The immediate cause of World War I that made the aforementioned items come into play (alliances, imperialism, militarism, and nationalism) was the assassination of Archduke Franz Ferdinand of Austria-Hungary. In June 1914, a Serbian-nationalist terrorist group called the Black Hand sent groups to assassinate the Archduke. Their first attempt failed when a driver avoided a grenade thrown at their car. However, later that day a Serbian nationalist named Gavrilo Princip shot the Archduke and his wife while they were driving through Sarajevo, Bosnia which was part of Austria-Hungary. They died of their wounds. The assassination was in protest to Austria-Hungary having control of this region: Serbia wanted to take over Bosnia and Herzegovina. The assassination of Ferdinand led to Austria-Hungary declaring war on Serbia. When Russia began to mobilize to defend its alliance with Serbia, Germany declared war on Russia. Thus began the expansion of the war to include all those involved in the mutual defense alliances.
effect: world war 1
cause: Imperialism
Imperialism is when a country increases their power and wealth by bringing additional territories under their control, usually without outright colonizing or resettling them. Before World War I, several European countries had made competing imperialistic claims in Africa and parts of Asia, making them points of contention. Because of the raw materials these areas could provide, tensions around which country had the right to exploit these areas ran high. The increasing competition and desire for greater empires led to an increase in confrontation that helped push the world into World War I.

cause: Mutual Defense Alliances
Countries throughout the world have always made mutual defense agreements with their neighbors, treaties that could pull them into battle. These treaties meant that if one country was attacked, the allied countries were bound to defend them. Before World War 1 began, the following alliances existed: Russia and Serbia ,Germany and Austria-Hungary, France and Russia ,Britain and France and Belgium, Japan and Britain .When Austria-Hungary declared war on Serbia, Russia got involved to defend Serbia. Germany, seeing that Russia was mobilizing, declared war on Russia. France was then drawn in against Germany and Austria-Hungary. Germany attacked France by marching through Belgium pulling Britain into war. Then Japan entered the war to support its British allies. Later, Italy and the United States would enter on the side of the Allies (Britain, France, Russia, etc.).
