The Empire of Rome dominated most of Europe and much of Africa and the Middle East. What is often overlooked though is the key role Rome's geography played in it's rise to power. There were two mountain ranges, the Alps and the Apennines protected Rome from invasion because it acted as a natural barrier to prevent armies from invading in those areas. This also forced enemies to push through narrow passages, allowing time for Rome to set up and defend. The fertile land in Rome also allowed for extensive amounts of agriculture. It is often cited that the soil in Rome is some of the most fertile soil in Europe. Finally Rome benefited from it position, allowing to become a center for trade. Rome was positioned in the center of the Mediterranean Sea, which made Rome a very desirable place for trade, even before Rome rose to power. All in all Rome's natural barriers, fertile land, and central location played a key role in its rise to power.
Hey there!
The Greek City-State of Sparta was a warrior society. Everyone was either respected to find and hunt for food or steal it, as they lived in a very mountainous isolated region- a big consequence of Greece's geography.
It was run by oligarchs. This meant that rich aristocrats ruled over them, and usually had laws in favor of the wealthy. That meant the rich got richer, and the poor lost their money, and got poorer. Perhaps this was the reason why there were so many hardships in Sparta, and this possibly led to its downfall.
Hopefully this helped!
