In this video Heimler walks you through Unit 7 Topic 2 (7.2) of AP World History, which is to say the causes of World War I.

The easiest way to remember the four main causes of the conflict is as follows: MAIN. Militarism refers to the build up of military personnel and weaponry. Alliances are the defensive treaties that several countries entered into. Imperialism caused an awful lot of tension between imperial powers as they raced to claim any available land to establish colonies. Nationalism is a strong identification with one's own nation, often at the expense of others.

With all of these causes swirling around and mounting, all it took was the assassination of archduke Franz Ferdinand at the hands of a Serbian nationalist group called the Black Hand, and we had ourselves a world war.

If you have any questions, leave them below and Heimler will answer them forthwithly.
