The Roman Empire mainly includes 43 countries, including Italy, France, Spain, Portugal, Austria, Switzerland, the Netherlands, Belgium, Luxembourg, Balkan countries, Turkey, Palestine, Israel, most of Britain, Germany, Poland and North African countries.
The Roman Empire was founded in 27 B.C. and perished in 1453, stretching for more than 1000 years. The land area is very large, spanning Europe, Asia and Africa, starting from Spain, Gaul and Britain in the west, the upper reaches of the Euphrates River in the East, North Africa in the South and the Rhine and Danube in the north. The Mediterranean became the inland sea of the Empire, controlling about 5 million square kilometers in its heyday.
The history of the Roman Empire was divided into two stages. In 395, Theodosius I divided the empire into two sons. From then on, the Roman Empire was divided into two and divided forever. In 476, the leader of the Roman mercenary, the Germanic odoyak, deposed the last emperor of Western Rome, and the Western Rome perished. Eastern Rome did not disintegrate until 1453.
