Ancient civilizations timeline by date and region

The earliest urban societies in this comparison appear in southern Mesopotamia during the fourth millennium BCE. Egypt and Caral-Supe developed by about 3000 BCE, followed by the urban Indus civilization, Bronze Age states in China and the Aegean, and later complex societies across Africa, the Mediterranean, Asia, and the Americas. They overlapped: this is not a ladder in which one “replaced” the next.

c. 3500–2000 BCE

Early Mesopotamian cities

Urban centers and cuneiform writing developed in southern Mesopotamia. “Mesopotamia” later included many distinct Sumerian, Akkadian, Babylonian, and Assyrian states.

West Asia · modern Iraq and neighboring regions

c. 3100–30 BCE

Ancient Egypt

The conventional span runs from early dynastic unification to the end of Ptolemaic rule. It contains kingdoms, intermediate periods, and foreign dynasties—not one unchanged empire.

North Africa · Nile Valley

c. 3000–1800 BCE

Caral-Supe

UNESCO dates the development of the Sacred City of Caral-Supe to this period. It was one center within the wider Norte Chico tradition.

South America · coastal Peru

c. 2600–1900 BCE

Urban Indus civilization

This is the mature urban phase associated with sites such as Harappa and Mohenjo-daro. Late Harappan regional cultures continued afterward.

South Asia · Pakistan and northwest India

c. 1900–1450 BCE

Minoan palatial Crete

Large palace centers flourished on Crete during the Bronze Age. “Minoan” is a modern archaeological label, not a name securely known from the people themselves.

Aegean · island of Crete

settled communities from c. 1800 BCE; Classic c. 250–900 CE

Ancient Maya societies

Maya cities and writing developed over long Preclassic and Classic periods. Maya peoples and languages continue today, so there is no honest single “end date.”

Mesoamerica · Mexico and Central America

c. 1600–1046 BCE

Shang dynasty

Archaeology and oracle-bone inscriptions document a Bronze Age royal state in northern China. Exact dates vary between chronological systems.

East Asia · Yellow River region

c. 1500–400 BCE

Olmec cultures

Major Gulf Coast centers included San Lorenzo and La Venta. “Olmec” covers related archaeological cultures rather than a single known empire.

Mesoamerica · Gulf Coast of Mexico

c. 1500–300 BCE

Phoenician city cultures

Independent coastal cities shared language, seafaring networks, and artistic traditions. They did not form one continuous Phoenician empire; western Punic societies developed their own histories.

Levant and Mediterranean coast

c. 900–31 BCE

Ancient Greek world

The Archaic and Classical periods saw many independent poleis, not a unified Greek nation-state. The broad range here also includes the later Hellenistic kingdoms and ends conventionally in 31 BCE.

Mediterranean · Greece and connected colonies

c. 760 BCE–350 CE

Kingdom of Kush

Kush ruled from Nubian centers including Napata and later Meroë. Its history was connected to, but distinct from, ancient Egypt.

Northeast Africa · modern Sudan

550–330 BCE

Achaemenid Persian Empire

Founded by Cyrus II, this imperial system governed a vast, multilingual territory through regional administrations before Alexander's conquest.

West and Central Asia · centered in Iran

509 BCE–476 CE in the West

Roman Republic and Empire

The date 476 marks the end of imperial rule in the western provinces, not the end of Roman civilization. The Eastern Roman Empire continued for nearly another millennium.

Mediterranean, Europe, North Africa, West Asia

c. 1st–7th centuries CE

Kingdom of Aksum

Aksum was tied to Red Sea trade, minted coins from the third century, and adopted Christianity under King Ezana in the fourth century.

Northeast Africa · Ethiopia and Eritrea

c. 1–650 CE

Teotihuacan city-state

Teotihuacan became one of the ancient Americas' largest cities and influenced wide parts of Mesoamerica. This range describes its principal urban trajectory, not every occupation at the site.

Mesoamerica · Basin of Mexico

c. 320–550 CE

Gupta Empire

The Gupta state ruled much of northern and central India. The label describes a political empire and should not be used as a synonym for all Indian civilization in that period.

South Asia · northern and central India

What existed at the same time?

Around 2500 BCE, Old Kingdom Egypt, cities in Mesopotamia, Caral-Supe, and the urban Indus civilization all existed in overlapping centuries. Around 500 BCE, Persian imperial power, Greek city-states, early Rome, Kush, late Egyptian dynasties, and complex societies in Mesoamerica also overlapped. The useful question is therefore not “what came next?” but “what was happening elsewhere at the same time?”

Around 350 CE, the Roman Empire, Kush, Classic Maya states, Teotihuacan, Aksum, and the Gupta Empire also coexisted. Ancient history was always global and simultaneous.

Why the dates differ between sources

Different definitions: one source may date the first settlement, another the first state, palace, writing system, or dominant artistic phase.
Changing evidence: radiocarbon results, inscriptions, and new excavations can revise a chronology.
Modern umbrella labels: terms such as “Minoan,” “Olmec,” and even “Mesopotamian civilization” group many communities and periods.
Political endings are not cultural endings: conquest or dynastic change rarely makes a population disappear.

Frequently asked questions

What was the earliest ancient civilization?

Southern Mesopotamia contains some of the earliest known cities and writing. But there is no universal moment when a settlement becomes a “civilization,” and early state societies developed independently in several regions.

Did all ancient civilizations exist one after another?

No. Many overlapped for centuries. Compare rows across regions rather than reading the list as a chain of winners and successors.

Are these dates exact?

No. Most are conventional and approximate. This page favors ranges from museums and UNESCO and tells you when a range refers only to a mature or classical phase.
