Those who learn from history make history; those who do not become history themselves. World history clearly shows that power is never permanent. Once-powerful nations have weakened over time, and some have even vanished into the annals of history.
Throughout the flow of time, the world’s superpowers have constantly shifted. Ancient Egypt (2600–1100 BC), the Achaemenid Persian Empire (550–330 BC), the Macedonian Empire (336–323 BC), the Roman Empire (27 BC–476 AD), and the Byzantine Empire (330–1453 AD) led the world during different eras.
In the Middle Ages, the influence of Islamic Caliphates lasted from the 7th to the 13th century, while the Mongol Empire (13th–14th century) and the Ottoman Empire (early 14th–15th century) dominated vast territories.
