Colonies in antiquity were post-Iron Age city-states founded from a mother-city (its "metropolis"), not from a territory-at-large. Bonds between a colony and its metropolis remained often close, and took specific forms during the period of classical antiquity. Generally, colonies founded by the ancient Phoenicians, Carthage, Rome, Alexander the Great and his successors remained tied to their metropolis, but Greek colonies of the Archaic and Classical eras were sovereign and self-governing from their inception. While Greek colonies were often founded to solve social unrest in the mother-city, by expelling a part of the population, Hellenistic, Roman, Carthaginian, and Han Chinese colonies were used for expansion and empire-building.
An Egyptian colony that was stationed in southern Canaan dates to slightly before the First Dynasty. Narmer had Egyptian pottery produced in Canaan and exported back to Egypt, from regions such as Arad, En Besor, Rafiah, and Tel ʿErani. Shipbuilding was known to the ancient Egyptians as early as 3000 BC, and perhaps earlier. The Archaeological Institute of America reports that the earliest dated ship — dating to 3000 BC – may have possibly belonged to Pharaoh Aha.
From Gadir the Phoenicians controlled access to the Atlantic Ocean and the trade routes to Britain. The most famous and successful of Phoenician colonies was founded by settlers from Tyre in 814–813 BC and called Kart-Hadasht (Qart-ḥadašt, literally "New Town"), known to history as Carthage. The Carthaginians later founded their own colony in the southeast of Spain, Carthago Nova, which was eventually conquered by their enemy, Rome.
According to María Eugenia Aubet, Professor of Archaeology at the Pompeu Fabra University, Barcelona: "The earliest presence of Phoenician material in the West is documented within the precinct of the ancient city of Huelva, Spain... The high proportion of Phoenician pottery among the new material found in 1997 in the Plaza de las Monjas in Huelva argues in favour, not of a few first sporadic contacts in the zone, but of a regular presence of Phoenician people from the start of the ninth century BC. The recent radiocarbon dates from the earliest levels in Carthage situate the founding of this Tyrian colony in the years 835–800 cal BC, which coincides with the dates handed down by Flavius Josephus and Timeus for the founding of the city."
In Ancient Greece, a vanquished people would sometimes found a colony, leaving their homes to escape subjection at the hand of a foreign enemy; sometimes colonies formed as a sequel to civil disorders, when the losers in internecine battles left to form a new city elsewhere; sometimes to get rid of surplus population, and thereby to avoid internal convulsions; and also, as a result of ostracism. But in most cases colony-founders aimed to establish and facilitate relations of trade with foreign countries and to further the wealth of the mother-city (in Greek: μητρόπολις mētropolis). Colonies were established in Ionia and Thrace as early as the 8th century BC.
More than thirty Greek city-states had multiple colonies. They became dotted across the Mediterranean world, with the most active colony-founding city, Miletus, of the Ionian League, spawning ninety colonies stretching throughout the Mediterranean Sea, from the shores of the Black Sea and Anatolia (modern Turkey) in the east, to the southern coast of the Iberian Peninsula in the west, as well as several colonies on the Libyan coast of northern Africa, from the late 9th to the 5th centuries BC.
Greeks founded two similar types of colony, one known as an ἀποικία apoikía – a designation reflecting the Greek roots ἀπό (apó “away from”) + οἶκος (oîkos “home”) (pl.: ἀποικίαι apoikiai) – and the other as an ἐμπόριov – emporion (pl.: ἐμπόρια emporia). The first type of colony was a city-state on its own; the second was a Greek trading-colony.
Two waves of new colonists set out from Greece at the transition between the "Dark Ages" and the start of the Archaic Period – the first in the early 8th century BC and a second burst of the colonizing spirit in the 6th century. Population growth and cramped spaces at home seem an insufficient explanation, while the economical and political dynamics produced by the competitive spirit between the frequently kingless Greek city-states – newly introduced as a concept and striving to expand their spheres of economical influence – better fits as their true incentive. Through this Greek expansion the use of coins flourished throughout the Mediterranean Basin.
Influential Greek colonies in the western Mediterranean – many of them in today's Italy — included Cyme, Rhegium (Rhegion) by Chalcis and Zankle (c. 8th century), Syracuse by Corinth/Tenea (c. 734 BC), Naxos by Chalcis (c. 734 BC), Massalia (the later Marseille, France, c. 598 BC) and Agathe (shortly after Massalia) by Phokaia, Elea (Italy) and Emporion (present-day Spain) by Phokaia/Massalia (c. 540 BC and early 6th century), Antipolis (nowadays France) by Achaea, Alalia (Corsica) by Phokaia/Massalia (c. 545 BC) and Cyrene (Cyrenaica, present-day Libya) by Thera (762/61 and 632/31 BC).
The Greeks also colonised modern-day Crimea in the Black Sea. The settlements they established there included the city of Chersonesos, at the site of modern-day Sevastopol. Another area with significant Greek colonies was the coast of ancient Illyria on the Adriatic Sea (e.g. the ancient "Aspalathos", modern-day Split, Croatia).
Cicero remarks on the extensive Greek colonization, noting that "It were as though a Greek fringe has been woven about the shores of the barbarians." Several formulae generally shaped the solemn and sacred occasions when a new colony set forth. If a Greek city decided to send out a colony, the citizenry almost invariably consulted an oracle, especially one such as the Oracle of Delphi, beforehand. Sometimes certain classes of citizens were called upon to take part in the enterprises; sometimes one son was chosen by lot from every house where there were several sons; and strangers expressing a desire to join were admitted. A person of distinction was selected to guide the emigrants and to make the necessary arrangements. It was usual to honor these founders of colonies, after their death, as heroes. Some of the sacred fire was taken from the public hearth in the Prytaneum, from which the fire on the public hearth of the new city was kindled. Just as each individual had his private shrines, so the new community maintained the worship of its chief domestic deities, the colony sending embassies and votive gifts to the mother-city's principal festivals for centuries afterwards.
The Mycenaeans Greeks by the 15th century BC had reached Rhodes, Crete, Cyprus, where Teucer is said to have founded the first colony, and the shores of Asia Minor. Moreover, Greeks were settled in Ionia and Pontus. Miletus in Ionia was an ancient Greek city on the western coast of Anatolia, near the mouth of the Maeander River. The Late Bronze Age, 13th century BC, Milesian saw the arrival in the area of Luwian language speakers from south central Anatolia calling themselves the Carians. Later in that century, other Greeks arrived. The city at that time rebelled against the Hittites Empire. After the fall of that empire, the city was destroyed in the 12th century BC and starting about 1000 BC was resettled extensively by the Ionian Greeks. Before the invasion from Persia in the middle of the 6th century BC, Miletus was considered the greatest and wealthiest of Greek Polis. Over several centuries, numerous Ancient Greek city-states were established on the coasts of Anatolia. Greeks started Western philosophy on the western coast of Anatolia (Pre-Socratic philosophy). Thales, Anaximander, Anaximenes, Diogenes of Apollonia were among of the renowned Milesian school philosophers. Heraclitus lived in Ephesus (/ˈɛfəsəs/; Greek: Ἔφεσος Ephesos; Turkish: Efes) another ancient Greek city and Anaxagoras was from Clazomenae, a city on the coast of Ionia and a member of the Ionian League. All Ancient Greek dialects were spoken in Anatolia depending on the origin of the City states and the list of ancient Greek theatres in Anatolia is one of the longest among all places Greeks had settled. In Pontus, Greeks traditionally lived in the region of Pontus, on the shores of today's Turkey's Black Sea and in the Pontic Alps, in northeastern Anatolia and the former Armenian province of Kars in Caucasus, and also in Georgia. Those from southern Russia, the Ukraine, and Crimea are often referred to as 'Northern Pontic Greeks', in contrast to those from 'South Pontus', which strictly speaking is Pontus proper. Those from Georgia, northeastern Anatolia, and the ones who lived in present-day Armenia are often referred to as 'Eastern Pontic Greeks' or Caucasus Greeks. The Greeks have founded well known cities to this day. The cities of Sinope (Greek: Σινώπη, Sinōpē) and Trabzon (Greek: Τραπεζοῦς Trapezous), were founded by Milesian traders (756 BC) as well as Samsun, Rize and Amasya. Greek was the lingua franca of Anatolia from the conquests of Alexander the Great up to the invasion of the Seljuk Turks in the eleventh century AD.
The relation between colony and mother-city, known literally as the metropolis, was viewed[by whom?] as one of mutual affection. Any differences that arose were resolved by peaceful means whenever possible, war being deemed excusable only in cases of extreme necessity. (Note though that the Peloponnesian War of 431 -404 BC broke out in part as a result of a dispute between Corinth and her colony of Corcyra. The charter of foundation contained general provisions for the arrangement of the affairs of the colony, and also some special enactments. A colony would usually adopt the constitution of the mother-city, but the new city remained politically independent. The "holy fire" of the metropolis was preserved in a special place to remind people of the common ties. If the colony sent out a fresh colony on its own account, the mother-city was generally consulted, or was at least requested to furnish a leader. Frequently the colonies, declaring their commitment to the various metropolitic alliances formed in the Greek mainland and for religious reasons, would pay tribute in religious centres, like Delphi, Olympia or Delos.
The cleruchs (κληροῦχοι, klêrouchoi) formed a special class of Greek colonists, each being assigned an individual plot of land (κλῆρος, klêros) in the place to which they had been assigned. The trade factories set up in foreign countries, such as Egypt, were somewhat different from the ordinary colonies, the members retaining the right of domicile in their own homeland and confining themselves to their own quarter in the foreign city.
Main article: Colonia (Roman)
It was an old custom in ancient Italy to send out colonies for the purpose of securing new conquests. The Romans, having no standing army, used to plant bodies of their own citizens in conquered towns as a kind of garrison. These bodies would consist partly of Roman citizens, usually to the number of three hundred; partly of members of the Latin League, in larger numbers. The third part of the conquered territory was handed over to the settlers. The coloniae civium Romanorum (colonies of Roman citizens) were specially intended to secure the two seacoasts of Italy, and were hence called coloniae maritimae. The coloniae Latinae, of which there was a far greater number, served the same purpose for the mainland.
The duty of leading the colonists and founding the settlement was entrusted to a commission usually consisting of three members. These men continued to stand in the relation of patrons (patroni) to the colony after its foundation. The colonists entered the conquered city in military array, preceded by banners, and the foundation was celebrated with special solemnities. The coloniae were free from taxes, and had their own constitution, a copy of the Roman, electing from their own body their Senate and other officers of State. To this constitution the original inhabitants had to submit. The coloniae civium Romanorum retained Roman citizenship, and were free from military service, their position as outposts being regarded as an equivalent. The members of the coloniae Latinae served among the socii, the allies, and possessed the so-called ius Latinum or Latinitas. This secured to them the right of acquiring property, the concept of commercium, and the right of settlement in Rome, and under certain conditions the power of becoming Roman citizens; though in course of time these rights underwent many limitations.
From the time of the Gracchi the colonies lost their military character. Colonization came to be regarded as a means of providing for the poorest class of the Roman Plebs. After the time of Sulla it was adopted as a way of granting land to veteran soldiers. The right of founding colonies passed into the hands of the Roman emperors during the Principate, who used it mainly in the provinces for the exclusive purpose of establishing military settlements, partly with the old idea of securing conquered territory. It was only in exceptional cases that the provincial colonies enjoyed the immunity from taxation which was granted to those in Italy.
Imperial China during the Han dynasty (202 BC - 220 AD) expanded to include what is now much of China proper as well as Inner Mongolia, northern Vietnam, northern Korea, the Hexi Corridor of Gansu, and the Tarim Basin region of Xinjiang on the easternmost fringes of Central Asia. After the nomadic Mongolic Xiongnu ruler Hunye (渾邪) was defeated in battle by Huo Qubing in 121 BC, settlers from various regions of China under the rule of Emperor Wu of Han colonized the Hexi Corridor and Ordos Plateau. Tuntian, self-sustaining agricultural military garrisons, were established in frontier outposts to secure the massive territorial gains and Silk Road trade routes leading into Central Asia. Emperor Wu oversaw the Han conquest of Nanyue in 111 BC, bringing areas of Guangdong, Guangxi, Hainan Island, and northern Vietnam under Han rule, and by 108 BC completed the Han conquest of Gojoseon in what is now North Korea. Han Chinese colonists in the Xuantu and Lelang commanderies of northern Korea dealt with occasional raids by the Goguryeo and Buyeo kingdoms, but conducted largely peaceful trade relations with surrounding Korean peoples who in turn became heavily influenced by Chinese culture.
In 37 AD the Eastern Han general Ma Yuan sent Han Chinese to the northeastern frontier and settled defeated Qiang tribes within Han China's Tianshui Commandery and Longxi Commandery. Ma pursued a similar policy in the south when he defeated the Trưng Sisters of Jiaozhi, in what is now modern northern Vietnam, resettling hundreds of Vietnamese into China's Jing Province in 43 AD, seizing their sacred bronze drums as rival symbols of royal power, and reinstating Han authority and laws over Jiaozhi. Historian Rafe de Crespigny remarks that this was a "brief but effective campaign of colonisation and control", before the general returned north in 44 AD.
Cao Song, an Eastern Han administrator of Dunhuang, had military colonies established in what is now Yiwu County near Hami in 119 AD. However, Empress Deng Sui, regent for the young Emperor Shang of Han, pursued a slow, cautious policy of settlement on the advice of Ban Yong, son of Ban Chao, as the Eastern Han Empire came into conflict with the Jushi Kingdom, the Shanshan and their Xiongnu allies located around the Taklamakan Desert in the Western Regions. In 127 AD Ban Yong was able to defeat the Karasahr in battle and colonies were established all the way to Turfan, but by the 150s AD the Han presence in the Western Regions began to wane. The late Eastern Han Empire under the control of chancellor Cao Cao established agricultural military colonies for settling wartime refugees. Towards the end of the Han dynasty, Cao Cao also established military colonies in Anhui province in 209 AD as a means to clearly demarcate a border between his realm and that of his political rival Sun Quan.
...at their new location, colonists were expected to retain ties with their metropolis. A colony that sided with its metropolis's enemy in a war, for example was regarded as disloyal...
