How can you search information on it?
Easy. You search the Rise of the Ottoman Empire. And their Impact on the Western World.
It's very easy. And when you found the information, you, in your own words, explain how they did it, and why they did, and what become of it.
Don't be lazy. You won't learn anything having others do you your work. The only way to learn, is by by finding the information yourself.
EDIT TO LARRY:
You know what's interesting. The Ottoman Turks were one of the links I posted. Because they were different, lol
