Moving along, Persian Empire was founded around 548 BC. It was the first largest empire stretching from Atlantic Ocean, Morocco, to Indus River, India. The Persian Empire is most famous for its tolerance over other religions and races and the first people to write the Charter of Human Rights. They also invented coins, roads, postal system, and many more innovations.
Furthermore, one of the best innovations, the Persian Empire invented was canal building. They built canals for various reasons: to have drinkable water, to water farms, and to dispose wastes. However, their greatest innovation came around in 525 BC. Now I ask you a question, where and when the Suez Canal was constructed? The Suez Canal lies between Middle East and Egypt and it was completed in 1869. But when European engineers were in the middle of constructing the canal they found a statue with some writing on it which said, "I, Darius the Great, King of Persia, King of Kings, King of the World, commanded my men to build a canal so that the East and West can easily trade with each other." They constructed the canal around 525 BC but years later when the Persian Empire was gone, the climate changed therefore the canal was destroyed. This will always be remembered as the greatest innovation of Persian Empire.
Moreover, their postal system was also famous because a mail could be delivered from one end of empire to the other end of empire in 12 days. They did this by using the relay stations and the purpose of the relay stations was that the messenger could switch his horse with another horse. The relay stations were built only so far distant from each other so that a horse could run without resting or feeding, therefore, the horses didn't die.
In conclusion, Persian Empire
