Cities have played an important role in human history for over 9,000 years.
Jericho, the oldest city on record with a population of 2,000,
was the center of commerce and learning in its day.
So was Uruk, Mari and other great cities through history to Tokyo,
 which is the largest city today.
Cities are becoming even more important as 
we passes through the biggest wave of urbanization in human history.


Determining the population of any city prior to the late 1700s is no easy task.
Even the most casual census was unheard of before then,
and studies to nail down city populations throughout history weren't even attempted until 1944.
It was then that Tertius Chandler and Gerald Fox undertook a 30 year study,
 completed in 1974, that looked at urban populations in 2,000 cities,
over several thousand years.
The numbers were drawn from the size of a city's military in peacetime and in war,
 household data, agricultural commerce, church records, fortification sizes,
 food distribution, loss of life in a disaster, and city comparisons.
applying greater detail and further research to his numbers.
In 2003, George Modelski expanded on Chandler's work and wrote
The book remains the authoritative reference on historic population today.
The data here is all based on Modelski's numbers,
except for London in 1825 which is Chandler's.
Jericho and Uruk, the two most ancient cities,
are based on estimates made from Modelski's work.


1. JERICHO: The world's largest city in 7000 BC

Population: 2,000
Present-day population: 14,674
Jericho may be the oldest continually occupied spot in the world, 
with settlements dating to 9,000 BC.
The city, nestled between the Dead Sea and Mt. Nebo,
 had natural irrigation from the
 the Jordan River and the best known oasis in the region.
The springs allowed residents to grow the highly lucrative  opobalsamum plant,
 which produced the most expensive oil in the ancient world.
At the dawn of the earth's prehistory,
 the residents of Jericho enjoyed architecture that included
 a religious shrine and painted skulls that made up the first ever attempt at portraiture.


2. URUK: The world's largest city in 3500 BC

Population: 4,000 people
Present day population: Ruins
Some believe Uruk to be the biblical city of Erech;
 the second city built by King Nimrod in the Book of Genesis.
The domestication of grain and its close proximity to
 the Euphrates River allowed Uruk's harvest to swell, 
leading to trade, advancements in writing, and specialized crafts.
Excavation in the region is difficult because older buildings 
were recycled into newer buildings throughout the ages.
Located between the Tigris and the Euphrates,
 Uruk went on to become part of Mesopotamia, meaning "land between rivers."

3. MARI: The world's largest city in 2400 BC

MARI: The world's largest city in 2400 BC

Population: 50,000
Present day population: Ruins
Mari was the robust trade capital of Mesopotamia, central in moving stone,
 timber, agricultural goods and pottery throughout the region.
Mari's government swelled along with its economy in the second century BC,
 and in the 1930's a French archaeologist discovered
 25,000 tablets written in an extinct language called Akkadian.
Most were municipal documents, economic reports and census rolls 
-- a third were personal letters.
The find changed our understanding of the ancient Near East.

4. UR: The world's largest city in 2100 BC

UR: The world's largest city in 2100 BC
Archeological excavations at Ur
Population: 100,000
Present day population: Ruins
In 2100 BC Ur was rich.
 The city held huge amounts of luxury items crafted from precious metals 
and semi-precious stones imported from throughout the known world.
Many consider Ur to be the city of Ur Kasdim mentioned in the Book of Genesis, 
birthplace of Abraham, mentioned four times in the Tora.
Because of possible drought, or changing river patterns,
 Ur was no longer inhabited after 500 BC.
Due to the sanctity for which Ur was renowned, in the years that followed, 
people throughout the region brought their dead to rest in the abandoned city.
When archaeologists began sincere excavations in the mid 1850s,
 they discovered an immense necropolis, or city of the dead.

5. YINXU: The world's largest city in 1300 BC

YINXU: The world's largest city in 1300 BC
Burial pit at Tomb of Lady Fu Hao in Yinxu
Population: 120,000
Present day population: Ruins
Yinxu is known for its immense deposits of Oracle Bones,
 which contain the earliest form of Chinese writing.
Pieces of ox bone and tortoise shell were inscribed using a bronze pin,
 heated until the bone cracked and then presented for divination.
Later when the tradition changed to ink and brush, 
entire genealogies and city histories were
written on the fragments and deposited in central pits.
Over the millennium Chinese farmers would unearth the chips and 
 sell them as "Dragon Bones," for use in traditional Chinese medicine.
The tortoise chips were used to treat malaria; the ox chips, knife wounds.

6. ABYLON: The world's largest city in 700 BC

BABYLON: The world's largest city in 700 BC

Population: 100,000
Present day population: Ruins
Babylon has an almost 4,000 year-old archaeological record a
 has encountered many setbacks with its excavation.
In 1983, Saddam Hussein started rebuilding on top of the old city and
 inscribed his name on most of the bricks used in construction,
 in the style of the Babylonian King Nebuchadnezzar.
They were highly sought collector's items following Hussein's downfall.
More recently, the U.S. occupation is decimating Babylonian relics as helipads,
 and parking areas are scraped from the desert.
 Soldiers have been found removing relics,
 and the antiquities market is booming since the occupation.
Donny George, an Iraqi official in charge of antiquities said that the
 "mess will take decades to sort out".
U.S. officials maintain the base was built there to protect the site from looters.

7. CARTHAGE: The world's largest city in 300 BC

Population: 500,000
Present day population: 20,715
20,000 urns, containing the charred and unscorched remains of 
Carthaginian newborns and infants were recently discovered in Carthage.
Buried between 400 and 200 BC, in a cemetery called the Tophet, 
the internment of the urns coincides with periods of extreme scarcity within the city.
It is not known whether the children were sacrificed in offering,
 or if famine, drought, and other hardships increased infant mortality
 and the remains were cremated.
Because all records of Carthaginian life
were destroyed by the Romans after the Third Punic War, 
the question may never be decided.
In 1985, the mayor of Rome and the Mayor of Carthage signed a peace treaty,
 officially ending that latent 2,100 year conflict.

8. ROME: The world's largest city in 200 AD

ROME: The world's largest city in 200 AD

Population: 1,200,000
Present day population: 2,754,440
From its humble roots as a small Italian village 1100 years earlier, Rome,
 in the second century AD, 
was enjoying the brief pinnacle of its influence and achievement.
At this time, the city was a military dictatorship under Septimius Severus; 
A move the people welcomed to correct the corruption instilled by
 Emporer Commodus.
 Recall Joaquin Phoenix in Gladiator -- that Commodus.
The city reached this size when it did because it relied on 
the food and taxes brought in from most of Europe and the Mediterranean.
Of course, it proved an untenable position. By 273 AD, 
Rome had less than 500,00 inhabitants and
 the Dark Ages could be seen looming on the horizon.

9. CONSTANTINOPLE:

The world's largest city in 600 AD

Population: 600,000
Present day population: 13,120,596
Constantinople was in a fight for its survival in the year 600.
The nomadic Avars and the 
Eastern European Bulgarians were crushing in on the city from the west,
 and the Persians had completely overwhelmed the city's defenses in the east.
The metropolis was spared through a combination of its walls, its navy, 
and the arrival of soon-to-be emperor, Flavius Heraclius Augustus,
who eventually routed the Persians from Asia Minor entirely.
The city is now known as Istanbul.
By 618, however, as the the Persian Wars
 dragged on and decimated the city's supply of grain from Egypt,
Constantinople's population dwindled to 
about one tenth what it was 18 years before.



10. BAGHDAD: The world's largest city in 900 AD

BAGHDAD: The world's largest city in 900 AD
House of Wisdom -- Baghdad
Population: 900,000
Present day population: 6,554,126
In the year 900, Baghdad was the center of the Golden Age of Islam -- 
A 500-year Mid-East renaissance that began with the founding of the city 
and ended in 1250 AD with the Mongol invasion.
Home to the House of Wisdom, 
where all the world's knowledge was laboriously transcribed into Arabic, 
Baghdad's enlightenment saved innumerable ancient texts from the western world.
This free exchange of ideas is probably what led to the population explosion, 
as traders from around the known world came to the city 
and exchanged farming techniques.
The result was the Arab Agricultural Revolution and
 a scientific approach to agriculture still used today.

11. KAIFENG: The world's largest city in 1200 AD

KAIFENG: The world's largest city in 1200 AD
Life in Kaifeng -- scroll
Population: 1,000,000
Present day population: 4,800,000
For centuries, because of its central location on four major canals,
 Kaifeng was the capital city for a huge swath of China.
By 1200, the city was surrounded by three rings of walls to offset the vulnerability.
Despite the fortifications, 
Kaifeng was an early casualty in what would become
a forty year war with the Mongols
 — it was sacked and its residents fled, in 1234.
Kaifeng is also home to the Kaifeng Jews
the most ancient Jewish population anywhere in China.


12.BEIJING: The world's largest city in 1500 AD

Population: 1,000,000
Present day population: 22,000,000
In the mid 1400s, to feed its growing population and vast number of troops,
 Beijing officials constructed the Jingtong storehouses 
to store the grain it received as tax from the region.
The practice helped control prices and prevent inflation until
 the city grew to be the largest in the world and the demand outgrew supply.
The population had also consumed all the forests in the region
 for housing and firewood by this time, 
so the residents of the city were using coal, 
mined from the Western Hills, for heat and fuel.
The resulting pollution changed the ecological makeup of the entire region.


13. AYUTTHAYA: The world's largest city in 1700 AD

Population: 1,000,000
Present day population: 54,888 
The island Ayutthaya, the capitol of Thailand for over 400 years,
 was often referred to as the most beautiful city 
in the world by the diplomats who traveled there.
It was so appealing, in fact, that in 1767 it was sacked by the Burmese, 
and the capital was moved to its current location in Bangkok.
Today, Ayutthaya is a city of ruins and is so unique that
 UNESCO named it a World Heritage Site in 1991 
and it's consistently mentioned in lists of "places to see before you die."


14. LONDON: The world's largest city in 1825 AD

Population: 1,335,000
Present day population: 13,945,000
While the British Empire was flung around the globe 
bringing in immense wealth for a small portion of England,
 London was largely a slum in 1825.
 Not until four years after the city reached the record 
for being the most populous in the world
did government activate a full-time police force.
Named after the Prime Minister at the time, Robert Peel,
 they're called "bobbies" to this day.
London retained the largest number of residents until 1914.

15. NEW YORK: The world's largest city in 1925 AD

Population: 7,774,000
Present day population: 8,175,133 
New York City took on its modern shape in 1914, 
when the Bronx was added as the fifth borough.
It was a city that looked to the future as it built skyscrapers
 and laid plans to build them even larger.
Despite the onset of the Great Depression in 1929
 New York went ahead and built the Chrysler Building,
 the Empire State Building, the Lincoln Building and 
One Wall Street by 1931, just to name a few.
The Dow Jones Stock exchange reached a high of 159 in 1925.
 It would more than double before the crash four years later.


16. TOKYO: The world's largest city in 1968 AD

TOKYO: The world's largest city in 1968 AD
Population: 20,500,000
Present day population: 32,450.000 
The economic toll of World War II continued 
to threaten Japan's economic future into the 1950s.
But by 1968, Japan had reached an economic and
 population growth curve that has carried it into the 21st century.
The years from 1950 through 1990 in Japan 
re referred to as the post-war economic miracle
the most prosperous time in Japan's history — ever.
The economic success was based on many factors,
 but perhaps most importantly was heavy U.S. investment and
a large measure of government intervention by the Japanese.
