Achaemenid Empire: Timeline and Major Facts
The Achaemenid Empire, also known as the first Persian Empire, was the famed ancient Iranian empire that emerged in prominence and might following the fall of the Neo-Babylonian Empire. Not only did the ancient Persians, under the reign of founder-king Cyrus the Great, defeat the Babylonians, but they also defeated the likes of Lydia in Western Asia Minor (present day western Turkey) and Medes (present day western and northern Iran).
From its hub in Western Asia, the Achaemenid Empire is reasoned to have reached its peak during the reign (486 BCE– 465 BCE) of Xerxes I (or Xerxes the Great), a mighty military commander who defeated many states in northern and central Greece, including the Athenians. With a size of about 2.1 million square miles (5.5 million square kilometers), the Achaemenid Empire was the largest empire up until that time. It has also been estimated that between 20-30 million inhabited the Persian Empire, which included places as far as Egypt and India’s Indus Valley.

In the article below, World History Edu presents a complete timeline of the Achaemenid Empire, from its beginning around the 6th and 7th centuries to its fall in 330 BCE when it fell to Alexander the Great of Macedonia.
553 BCE: Cyrus II of the Ashan (c. 600 BCE-530 BCE) successfully revolts against the Median Empire.
550 BCE: The first Persian Empire is founded (by Cyrus the Great) after the Median capital city Ecbatana is taken.
546 BCE: The Lydian Kingdom falls to the might of Cyrus the Great’s army.
539 BCE: After years of fighting, the Persians claim victory over the Neo-Babylonian Empire with the capture of the city of Babylon.
530 BCE: Cyrus the Great dies during a military campaign against an Eastern Iranian nomadic group of tribes in Central Asia. Cyrus was succeeded by his son Cambyses II (reign- 525 BCE – 522 BCE).
525 BCE: Cambyses II takes areas in Cyprus and Phoenicia (located in the Levant region of the eastern Mediterranean).
526 BCE: Cambyses II defeats newly installed Egyptian pharaoh Psamtik III. Cambyses II crowns himself pharaoh of Egypt.

480 BCE: Xerxes I (also known as Xerxes the Great) assembles several hundreds of thousands of soldiers, perhaps the largest army up until then, to avenge his father’s defeat at Marathon. His army secures victory at the Battle of Themopylae and goes ahead to sack the city of Athens. However, Xerxes’ fleet loses to a Greek coalition at the Battle of Salamis.
479 BCE: The Greeks destroy the remaining Persian army in Athens at the Battle of Plataea. In the ensuing years, several Persian held territories in Asia Minor begin to revolt, including Macedonia.

Six months later, the Sogdianus himself was executed his half-brother Ochus (later Darius II), who takes the throne.

Interesting facts about the Achaemenid Empire
- Persian kings had titles such as King of Kings, Great King, King of Persia, Pharaoh of Egypt, and King of Countries.
- In 1979, the ancient city of Persepolis was named a UNESCO World Heritage Site. Situated in modern day southern Iran, Persepolis was a very important capital city of the Achaemenid Empire. Owing to its rich history, the location is considered one of the greatest archaeological sites in the world
- Cyrus the Great was from one of the very distinguished tribes in Ashan. He started off by defeating and bringing a number of kingdoms in the region under his control. Those kingdoms included Media, Lydia and Neo-Babylonia.
- Owing to how much territory that it controlled, the Achaemenid Empire is often hailed as the first superpower in history.
- Much of what we know about Cyrus the Great comes from an ancient artefact known as the Cyrus Cylinder. The inscriptions on the clay cylinder date to around 539 BCE, explaining how the mighty Persian ruler Cyrus brought Babylon (under the rule of King Nabonidus) to its knees.
- The Achaemenid Empire was further strengthened and unified by Cyrus’ descendant Darius the Great who used standardized weights and measurements to make economic activities in the region move on smoothly. The Achaemenid Empire was also boosted by the fact that it had a standard currency and developed road networks that linked the various trading hubs in the empire.
- It has been stated that the name “Persian” was derived from the tribal name
- King Artaxerxes II’s reign from 404 BCE to 358 BCE made him the longest reigning Persian king. His reign was praised for its tolerance of diversity, relative peace and economic growth.
- Alexander the Great, the Greek conqueror of Persia, was said to have been a strong admirer of Cyrus the Great.
- The name “Achaemenid” means “the family of the Achaemenes”. Achaemenes is largely recognized as the ancestor of the dynasty of rulers of Persia. He ruled over the Anshan (in southwestern Iran) around the 7th century BCE. There have been some claims that he was a mythical figure.
- The Persian capital city, Persepolis, is actually the Greek name for “Persian City”.
- The first nomadic Persians first settle in the present-day Iran around 1000 BC. They made the Zagros Mountains their home.
How large was the Achaemenid Empire?
Inheriting a kingdom that was firmly on the ascendency, Darius the Great, a descendant of Cyrus the Great and the fourth king of the Achaemenid Empire, is believed to have taken the empire to heights never seen before. Under Darius’ reign, the empire was mightier and larger than any previous empire in history. It covered areas from West Asia and the Caucasus to modern-day Balkans, parts of northern Africa, and Central Asia.
To put into perspective how massive the Achaemenid empire was, one just needs to note that it ruled over three ancient civilizations and regions of the past – the Mesopotamia region, Egypt’s Nile Valley and the Indus Valley in India.

How did the Persian Empire fall?
Historians state that the latter part of the 5th century BCE witnessed the beginning of the end of Achaemenid Empire. It began with calamitous attempt by Xerxes I to invade Greek lands in 480 BC. Soon the tides turned and ancient Persia had to dig deep into its coffers to defend its vast border regions.
The Persian rulers had no option than to raise taxes on its already heavily taxed population. Owing to this and many other social strife, the Persian Empire stood no chance when Alexander the Great and his very capable Macedonian army invaded Persia in 330 B.C.
Alexander the Great dealt such a heavy blow to the Achaemenid dynasty that all attempts to resuscitate it proved futile. And so the curtain closed in on the Achaemenid rulers, making way for reign of Alexander’s most trusted generals, i.e. the Ptolemaic Kingdom.
