I have to write about a famous historical event that took place at the beginning of the Twentieth Century, can you help?
user
Sure, what do you know about the 1910's?
assistant
I don't know much about the 1910s. Did a famous historical event take place then?
user
I’m not sure. Do you want me to learn more about it?
assistant
Well, I'd just like to focus on one particular event that take place around this time.
user
I don't know much about this time period, so I'm not sure which one you might mean. If you can give me a little more context, I can try to learn more about it.
assistant
Ah, I see that World War 1 began in 1914.
user
I was actually referring to the global flu pandemic that happened around this time, but now that you mention it I think that the World War 1 events might be related. I'll see what I can learn.
assistant
Okay. Well, I think I'd just like to focus on one particular event that led to the start of the First World War. The paper I'm writing is only short.
user
How about the assassination of Archduke Franz Ferdinand? I know a little bit about that one.
assistant
Great. Yes, that would be perfect.
user
As you probably know, Archduke Franz Ferdinand was assassinated by Gavrilo Princip, a student from Bosnia. He shot the Archduke and his wife.

Well, I looked at the Wikipedia entry and the article on it, and I think that's a good place to start. Let's have a look together:

1.  Archduke Franz Ferdinand is assassinated in Serbia.
2.  On this date Austria-Hungary declared war on Serbia.
3.  On this date Serbia issued an ultimatum to the Austro-Hungarian Empire.
4.  On this date Austria-Hungary declared war on Russia, Russia retaliated, and Germany declared war on Russia.
5.  On this date Germany declared war on France, and that set off a war involving several countries.
