Hello,
The first step when constructing a briefing is to collect material.
Access to food, water, shelter, and all basic human needs can hinder or help the growth of a civilization. Civilizations with similar environments or climates tend to develop on similar paths (because they run into the same problems/conveniences that have to be solved by human brains, which are wired to react to certain situations in certain ways.)
Big Idea. When Justinian became emperor in 527, he was determined to revive the ancient Roman Empire, to build a new Rome. He established Constantinople as the capital of the Byzantine or Eastern Roman Empire and preserved Roman heritage for more than a thousand years.
Germany lost substantial territory had severe restrictions placed on its military operations and was forced to acknowledge 'war guilt' and pay reparations to the Allies .
