If you’re interested in learning about or teaching World War I, primary source documents are an excellent place to start. These documents provide a firsthand account of the events that took place during this pivotal time in history. By reading primary source documents, you can gain a deeper understanding of the causes, events, and consequences of the various aspects of the “Great War”.
There are tens of thousands of primary sources covering World War I. These documents were written by people who lived during the time of the revolution, and they offer a unique perspective on the events that unfolded.
I’ve chosen several sources that address parts of the war most teachers cover in their content.
To access a copy of these documents, simply click on the button below.
The Zimmermann Telegram (1917)
The Zimmerman Telegram was a secret message from the German Foreign Secretary to the German ambassador in Mexico, proposing a military alliance against the United States.

The War Effort at Home
There are so many great posters and examples of pro-war propaganda available. Following are 2 posters encouraging the war effort and a photo of a German-American who was tarred and feathered, ostensibly because he did not support the war bond effort.


Conclusion
I hope these primary sources got your juices flowing with lesson ideas! Students can spend an entire period analyzing just one source or take in several during a gallery walk. The possibilities are endless.
One thing is clear, however. Utilizing primary sources in your classroom increases rigor and an appreciation for a bunch of “old dead guys”.
