Journey through the fascinating history and heritage sites of Iraq.
Iraq offers an extraordinary journey through the cradle of civilization, from the ancient Mesopotamian ruins to the bustling streets of Baghdad and the stunning mountains of Kurdistan. Experience authentic Middle Eastern culture, world-class archaeological sites, and warm hospitality in this historically rich nation.
Iraq is the cradle of human civilization, encompassing ancient Mesopotamia where writing, law, and urban life were invented. The land between the Tigris and Euphrates rivers nurtured the world's first cities (Uruk, Ur, Eridu) and empires (Akkadian, Babylonian, Assyrian), before passing through Persian, Greek, Parthian, Sasanian, and Islamic rule. The Abbasid Caliphate made Baghdad the intellectual capital of the medieval world, and the region's layered history from 7,000 BC to the present makes it one of the most archaeologically significant countries on earth.
Key moments in Iraq's history.
Agricultural communities establish permanent settlements in the fertile alluvial plains between the Tigris and Euphrates. The preconditions for urban civilization — irrigation, surplus food, social organization — emerge for the first time in human history.
The city of Uruk (modern Warka) becomes the world's first true city with a population exceeding 50,000. The Sumerians develop cuneiform writing — humanity's oldest writing system — initially for accounting grain supplies, then evolving into literature.
Sargon of Akkad establishes history's first empire, uniting Sumerian city-states under centralized rule. Akkadian becomes the lingua franca of the ancient Near East, and the empire stretches from Anatolia to the Persian Gulf.
The city of Ur under King Ur-Nammu reaches its zenith, constructing the Great Ziggurat of Ur (still standing today). The world's first recorded law code (Ur-Nammu Code) is promulgated, predating the Code of Hammurabi by 300 years.
King Hammurabi of Babylon unifies Mesopotamia and issues his famous Code of Hammurabi — 282 laws carved on a 2.25-meter stele. The code establishes principles of justice including 'presumption of innocence' that influence law codes to this day.
Nebuchadnezzar II's Babylonian empire destroys Nineveh and establishes the most powerful kingdom in the Near East. Babylon becomes the world's largest city with the Ishtar Gate, Hanging Gardens (one of the Seven Wonders), and the ziggurat Etemenanki inspiring the Tower of Babel story.
The Achaemenid Persian Empire under Cyrus the Great captures Babylon without resistance, freeing the Jewish captives in what is recorded in the Bible. Iraq becomes the most prosperous satrapy of the Persian Empire for the next two centuries.
Alexander defeats Persian King Darius III at the Battle of Gaugamela (near modern Erbil) and captures Babylon. Alexander dies in Babylon in 323 BC, planning to make it capital of his empire.
The Sasanians establish their capital at Ctesiphon (near modern Baghdad), building the magnificent Taq Kasra arch — the world's largest single-span brick arch still partially standing. Ctesiphon becomes the largest city in the world at its peak.
Arab Muslim forces defeat the Sasanian army at the Battle of Al-Qadisiyyah, ending Persian rule over Iraq. Islam rapidly becomes the dominant religion, and Arabic supplants Aramaic as the primary language over the following century.
Caliph Al-Mansur founds the circular city of Baghdad (Madinat al-Salam) as capital of the Abbasid Caliphate. Under Caliph Harun al-Rashid and Al-Ma'mun, Baghdad becomes the world's largest city and foremost center of science, philosophy, medicine, and literature — the Islamic Golden Age.
Hulagu Khan's Mongol forces destroy Baghdad in one of history's most catastrophic acts of urban destruction, killing the Caliph Al-Musta'sim and up to 800,000 people. The House of Wisdom — greatest library of the medieval world — is destroyed, ending the Abbasid Caliphate.
Ottoman Sultan Suleiman the Magnificent captures Baghdad from Safavid Persia, beginning nearly four centuries of Ottoman rule over Iraq. The region becomes a contested frontier between Ottoman and Safavid empires, with Baghdad changing hands multiple times.
Following World War I, Britain establishes a League of Nations mandate over Iraq. The Great Iraqi Revolution of 1920 — a major anti-colonial uprising — forces Britain to grant greater Iraqi self-governance, establishing the foundation for the modern Iraqi state.
Iraq becomes the first Arab country to gain independence from European mandate status, joining the League of Nations as the Kingdom of Iraq under King Faisal I. Oil is discovered near Kirkuk in 1927, transforming Iraq's economic potential.
The US-led coalition invades Iraq and topples Saddam Hussein's Ba'athist government. The subsequent decade of insurgency, the 2014-2017 ISIS occupation of Mosul and western Iraq, and subsequent reconstruction have shaped contemporary Iraq's complex political and security landscape.
Must-visit places for history enthusiasts.
The ruins of one of the ancient world's greatest cities, where Nebuchadnezzar II built the Ishtar Gate, Hanging Gardens, and the Tower of Babel. The reconstructed Ishtar Gate with its brilliant blue glazed bricks and relief sculptures of lions and dragons is Iraq's most iconic archaeological image.
The best-preserved ziggurat in Iraq, built by King Ur-Nammu as a temple to the moon god Nanna. Standing 30 meters high and measuring 64x46 meters at the base, it rises dramatically from the flat desert and is one of the world's most important archaeological monuments.
UNESCO World Heritage Site and the oldest continuously inhabited settlement on earth, where people have lived on this 30-meter mound for at least 7,000 years. The current Ottoman-era townhouses date from the 18th-19th centuries, and restoration work by the Aga Khan Trust continues.
The surviving half of the magnificent Taq Kasra arch — the world's largest single-span brick arch at 37 meters high and 26 meters wide — is all that remains of the great Sasanian palace complex at Ctesiphon, once the largest city in the world.
A UNESCO World Heritage Site and the best-preserved Parthian city in the world, featuring magnificent temple complexes combining Hellenistic and Eastern architectural styles. Hatra withstood Roman sieges led by both Trajan and Septimius Severus.
The ancient Assyrian capital where enormous winged bull lamassu guardian statues once stood. Though partially destroyed by ISIS in 2015, restoration work has begun and the site remains a moving testament to Iraq's ancient civilization and its vulnerability.
Built by Caliph Al-Mustansir II in 1227, this is one of the oldest universities in the world and a masterpiece of Abbasid Islamic architecture. The madrasa once taught all four schools of Islamic law simultaneously, representing the pluralistic intellectual tradition of Baghdad at its height.
One of the holiest sites in Shia Islam, housing the tomb of Imam Ali ibn Abi Talib (Prophet Muhammad's cousin and son-in-law). The golden dome and minarets rise magnificently over the old city of Najaf, and millions of pilgrims visit annually.

Explore history period by period.
4000 BC — 2300 BC
The world's first urban civilization emerges in southern Mesopotamia, inventing writing (cuneiform), the wheel, and complex social organization. City-states like Ur, Uruk, Eridu, and Lagash build ziggurats and develop sophisticated art, law, and religion.
2300 BC — 539 BC
Successive empires — Akkadian, Babylonian, Kassite, Assyrian, and Neo-Babylonian — transform Mesopotamia into the most powerful political entity of the ancient world. Babylon's Ishtar Gate, Hammurabi's Law Code, and Assyrian palace reliefs define this era.
750 AD — 1258 AD
Baghdad under the Abbasids becomes the world's largest city (population ~1 million) and the intellectual capital of the medieval world. The House of Wisdom (Bayt al-Hikma) translates Greek, Persian, and Indian knowledge into Arabic, preserving and advancing human learning.
1920 AD — Present
After four centuries of Ottoman rule, Iraq gained independence in 1932 under Hashemite monarchy rule. The 1958 Republic, Ba'athist rule, Gulf Wars, 2003 invasion, and ISIS occupation (2014-2017) have profoundly shaped modern Iraq, now in a period of reconstruction and development.
