Tiber river and trade
The city of Rome itself has tremendous environmental advantages, which made it easier for Rome to become an important city. Rome is located at the first place that people can easily cross the Tiber river, so it is the natural location of the main north-south road in Italy.
The reason you can cross the Tiber at Rome is that there is an island in the river there (this is the same as at Paris, and many other cities). Probably the first Romans made a lot of profit from charging people to let them use the island to cross the river – charging tolls.
Salt flats near the city of Rome
There are also big salt flats near the city. Because salt was so valuable in the ancient world for preserving meat and fish, selling the salt made Romans rich. Also the riverboats going up and down the Tiber, from east to west and back again, could stop at Rome. So right from the beginning, the ancient Roman environment helped the Romans get rich.
Roman empire’s many climate zones
The Romans also had the advantage of a good climate. During most of the time of the Roman Empire, Europe and the Mediterranean were unusually warm, about as warm as they are right now. That weather seems to have been good for Roman farming. The Romans brought Mediterranean crops like wine grapes and olives much further north than they normally grew.
Climate change and the fall of Rome
But during the 200s AD, the weather got cooler. The cooler weather forced wine and olive growers to move south. It may even have made it harder to grow wheat and barley. The cooler weather made it harder to heat houses in the north.
This may have helped cause problems for the Romans. The cold weather may have encouraged the Germans and the Sassanians to invade the Roman Empire. It may have encouraged many people to revolt inside the Empire as well.
