Kos or Cos (Greek: Κως) is a Greek island of the group of the Dodecanese, next to the Gulf of Gökova/Cos. The island measures 40 by 8 kilometres (25 by 5 miles), and is 4 km (2 miles) from the coast of Bodrum, Turkey, and the ancient region of Caria. The island constitutes a municipality within the Kos regional unit, which is part of the South Aegean region. The principal town of the island and seat of the municipality is Kos town. The island has a population of 33,388.
In the West, it was formerly known as Stancho, Stanchio, or Stinco, and in Ottoman and modern Turkish it is known as İstanköy, all from the Greek expression εις την Κω 'to Kos'; cf. the similar Stamboul and Stimpoli, Crete. Under the rule of the Knights Hospitaller of Rhodes, it was known as Lango or Langò, presumably because of its length. In The Travels of Sir John Mandeville, the author misunderstands this, and treats Lango and Kos as distinct islands.
In Italian, it is known as Coo.
A person from Kos is called a "Koan" in English. The word is also an adjective, as in "Koan goods".
The island was originally colonised by the Carians. The Dorians invaded it in the 11th century BC, establishing a Dorian colony with a large contingent of settlers from Epidaurus, whose Asclepius cult made their new home famous for its sanatoria. The other chief sources of the island's wealth lay in its wines and, in later days, in its silk manufacture.
Its early history–as part of the religious-political amphictyony that included Lindos, Kamiros, Ialysos, Cnidus and Halicarnassus, the Dorian Hexapolis (Greek for six cities),–is obscure. At the end of the 6th century, Kos fell under Achaemenid domination but rebelled after the Greek victory at the Battle of Mycale in 479. During the Greco-Persian Wars, before it twice expelled the Persians, it was ruled by Persian-appointed tyrants, but as a rule it seems to have been under oligarchic government. In the 5th century, it joined the Delian League, and, after the revolt of Rhodes, it served as the chief Athenian station in the south-eastern Aegean (411–407). In 366 BC, a democracy was instituted. In 366 BC, the capital was transferred from Astypalaia to the newly built town of Kos, laid out in a Hippodamian grid. After helping to weaken Athenian power, in the Social War (357-355 BC), it fell for a few years to the king Mausolus of Caria.
Proximity to the east gave the island first access to imported silk thread. Aristotle mentions silk weaving conducted by the women of the island. Silk production of garments was conducted in large factories by women slaves.
In the Hellenistic age, Kos attained the zenith of its prosperity. Its alliance was valued by the kings of Egypt, who used it as a naval outpost to oversee the Aegean. As a seat of learning, it arose as a provincial branch of the museum of Alexandria, and became a favorite resort for the education of the princes of the Ptolemaic dynasty. During the hellenistic age, there was a medical school; however, the theory that this school was founded by Hippocrates (see below) during the classical age is an unwarranted extrapolation. Among its most famous sons were the physician Hippocrates, the painter Apelles, the poets Philitas and, perhaps, Theocritus.
Diodorus Siculus (xv. 76) and Strabo (xiv. 657) describe it as a well-fortified port. Its position gave it a high importance in Aegean trade; while the island itself was rich in wines of considerable fame.  Under Alexander the Great and the Egyptian Ptolemies the town developed into one of the great centers in the Aegean; Josephus quotes Strabo to the effect that Mithridates was sent to Kos to fetch the gold deposited there by the queen Cleopatra of Egypt. Herod is said to have provided an annual stipend for the benefit of prize-winners in the athletic games, and a statue was erected there to his son Herod the Tetrarch ("C. I. G." 2502 ). Paul briefly visited here according to Acts 21:1.
Except for occasional incursions by corsairs and some severe earthquakes, the island has rarely had its peace disturbed. Following the lead of its larger neighbour, Rhodes, Kos generally displayed a friendly attitude toward the Romans; in 53 AD it was made a free city. Lucian (125–180) mentions their manufacture of semi-transparent light dresses, a fashion success.
The bishopric of Cos was a suffragan of the metropolitan see of Rhodes. Its bishop Meliphron attended the First Council of Nicaea in 325. Eddesius was one of the minority Eastern bishops who withdrew from the Council of Sardica in about 344 and set up a rival council at Philippopolis. Iulianus went to the synod held in Constantinople in 448 in preparation for the Council of Chalcedon of 451, in which he participated as a legate of Pope Leo I, and he was a signatory of the joint letter that the bishops of the Roman province of Insulae sent in 458 to Byzantine Emperor Leo I the Thracian with regard to the killing of Proterius of Alexandria. Dorotheus took part in a synod in 518. Georgius was a participant of the Third Council of Constantinople in 680–681. Constantinus went to the Photian Council of Constantinople (879). Under Byzantine rule, apart from the participation of its bishops in councils, the island's history remains obscure. It was governed by a droungarios in the 8th/9th centuries, and seems to have acquired some importance in the 11th and 12th centuries: Nikephoros Melissenos began his uprising here, and in the middle of the 12th century, it was governed by a scion of the ruling Komnenos dynasty, Nikephoros Komnenos.
Following the Fourth Crusade, Kos passed under Genoese control, although it was retaken in ca. 1224 and kept for a while by the Empire of Nicaea. In the 1320s, Kos nominally formed part of the realm of Martino Zaccaria, but was most likely in the hands of Turkish corsairs until ca. 1337, when the Knights Hospitaller took over the island. The last Hospitaller governor of the island was Piero de Ponte.
The Ottoman Empire captured the island in early 1523. The Ottomans ruled Kos for 400 years, neglecting the island, until it was transferred to Italy in 1912 after the Italo-Turkish War. The Italians developed the infrastructures of the island, after the ruinous earthquake of 23 April 1933, which destroyed a great part of the old city and damaged many new buildings. Architect Rodolfo Petracco drew up the new city plan, transforming the old quarters into an archaeological park, and dividing the new city into a residential, an administrative, and a commercial area., In World War II, the island, as Italian possession, was part of the Axis. It was controlled by Italian troops until the Italian surrender in 1943. On that occasion, 100 Italian officers who had refused to join the Germans were executed. British and German forces then clashed for control of the island in the Battle of Kos as part of the Dodecanese Campaign, in which the Germans were victorious. German troops occupied the island until 1945, when it became a protectorate of the United Kingdom, which ceded it to Greece in 1947.
In the late 1920s about 3,700 Turks lived in Kos, slightly less than 50% of the population, settled mainly in the west part of the city.
A 21-month British child disappeared in 1991, triggering an extensive investigation and international publicity. The child has never been found.
In 2011, Kos city was merged with two other municipalities, creating the new Kos municipality: the three municipalities became municipal units:
Kos is in the Aegean Sea. Its coastline is 112 kilometres (70 miles) long and it extends from west to east.
In addition to the main town and port, also called Kos, the main villages of Kos island are Kardamena, Kefalos, Tingaki, Antimachia, Mastihari, Marmari and Pyli. Smaller ones are Zia, Zipari, Platani, Lagoudi and Asfendiou.
The island is part of a chain of mountains from which it became separated after earthquakes and subsidence that occurred in ancient times. These mountains include Kalymnos and Kappari which are separated by an underwater chasm c. 70 metres (230 ft) (40 fathoms deep), as well as the volcano of Nisyros and the surrounding islands.
There is a wide variety of rocks in Kos which is related to its geographical formation. Prominent among these are the Quaternary layers in which the fossil remains of mammals such as horses, hippopotami and elephants have been found. The fossilised molar of an elephant of gigantic proportions was presented to the Paleontology Museum of the University of Athens.
The main religion practiced is Greek Orthodoxy. Kos has one of the four cathedrals in the entire Dodecanese. There is also a Roman Catholic church on the island as well as a Mosque catering to the Turkish-speaking Muslim community of Kos. The Synagogue is no longer used for religious ceremonies as the Jewish community of Kos was practically wiped out by the Nazis in World War II. It has, however, been restored and is maintained with all religious symbols intact and is now used by the Municipality of Kos for various events, mainly cultural.
Tourism is the primary industry. Some are attracted to the beaches. The main port and population centre on the island, also called Kos, is also the tourist and cultural centre, with whitewashed buildings including many hotels, restaurants and a small number of nightclubs forming the Kos town "barstreet".
Farming is the second principal occupation, with the main crops being grapes, almonds, figs, olives, and tomatoes, along with wheat and corn. Cos lettuce may be grown here, but the name is unrelated.
The ancient market place of Kos was considered one of the biggest in the ancient world. It was the commercial and commanding centre at the heart of the ancient city. It was organized around a spacious rectangular yard 50 metres (160 ft) wide and 300 metres (980 ft) long. It began in the Northern area and ended up south on the central road (Decumanus) which went through the city. The northern side connected to the city wall towards the entrance to the harbour. Here there was a monumental entrance. On the eastern side there were shops. In the first half of the 2nd century BC, the building was extended toward the interior yard. The building was destroyed in an earthquake in 469 AD.
In the southern end of the Market, there was a round building with a Roman dome and a workshop which produced pigments including “Egyptian Blue”. Coins, treasures, and copper statues from Roman times were later uncovered by archeologists. In the western side excavations led to the findings of rooms with mosaic floors which showed beastfights, a theme quite popular in Kos.
The ancient physician Hippocrates is thought to have been born on Kos, and in the center of the town is the Plane Tree of Hippocrates, a dream temple where the physician is traditionally supposed to have taught. The limbs of the now elderly tree are supported by scaffolding. The small city is also home to the International Hippocratic Institute and the Hippocratic Museum dedicated to him. Near the Institute are the ruins of Asklepieion, where Herodicus taught Hippocrates medicine. Kardamena is a popular resort for young British holidaymakers and has a large number of bars and nightclubs.
