In 330 AD, Constantine, then the emperor of the Roman Empire, moved the seat of power to Constantinople. Then, Constantine founded a "second Rome" (the Byzantine Empire).

The treaty of Versailles was a peace breaker (apparently), therefore, ending World War I. It brought Germany to great suffering; "...starving the children..." - I don't remember who that was by, but its important quote to know. That's only the partial speech, search up the speech and hopefully, you'll find it, otherwise ask your History teacher.
Nine nations created by the Treaty: Poland, Estonia, Finland, Czechoslovakia, Hungary, Yogoslavakia, Latvia, Estonia, and Austria.
Germany was deprived of 12.5 percent of population, 10 percent of the land, all of its colonies, 16 percent of its natural resources (steel, gold etc)...War Guilt Clause 231... These are some important notes to take. However, the allies did not cut off their oil supply, this, in turn, helped Germany perp for WWII.
If you're writing about Hitler's Rise to Power, you could also include the Policy of Appeasement, and ofc the Treaty of Versailles.
I hope this helped :)
