Query: When was Constantinople established?
Constantinople (; ) was the capital city of the Roman/Byzantine Empire (330–1204 and 1261–1453), and also of the brief Crusader state known as the Latin Empire (1204–1261), until finally falling to the Ottoman Empire (1453–1923). It was reinaugurated in 324 from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, and dedicated on 11 May 330. The city was located in what is now the European side and the core of modern Istanbul.
The original Academy of Plato had been destroyed by the Roman dictator Sulla in 86 BC. Several centuries later, in 410 AD, a Neoplatonic academy was established that had no institutional continuity with Plato's Academy, and which served as a center for Neoplatonism and mysticism. It persisted until 529 AD when it was finally closed by Justinian I. Other schools in Constantinople, Antioch, and Alexandria, which were the centers of Justinian's empire, continued.
After the conquest of Istanbul by Mehmed the Conqueror at 1453, construction of the Topkapı Palace was started in the year 1460 and completed in 1478. The palace was built upon a 700,000 square meter area on an Eastern Roman Acropolis located on the Istanbul Peninsula between the Sea of Marmara, Bosphorus and the Golden Horn. Topkapı Palace was the administrative, educational, and art center of the Empire for nearly four hundred years from Mehmed the Conqueror until Sultan Abdulmecid who was the thirty-first Sultan. Although Topkapi Palace was abandoned by the Ottoman Dynasty by moving to the Dolmabahçe Palace in the middle of the 19th century, Topkapı Palace retained its importance.
During the Byzantine era, the metropolis of Chalcedon was always recorded in the lists of the "Notitiae Episcopatuum", where it usually ranked 9th. There is no exact information about the extent of its ecclesiastical jurisdiction, but it probably coincided with the city of Chalcedon in addition to a number settlements on the Asian shore of the Bosporus. In the early Ottoman period the area of the metropolis was expanded to the east to include Pontoherakleia (modern Ereğli) and Amastris (modern Amasra), while it also included the Princes' Islands. From the late 19th century it was further expanded and covered an extensive and narrow strip on the Black Sea coast, stretching from Rysion (modern Darıca) on the Propontis to Zonguldak.
The chief towns of Upper Moesia (and wider) were: Singidunum (Belgrade), Viminacium (now Old Kostolac), Remesiana (now Bela Palanka), Naissos (Niš), and Sirmium (now Sremska Mitrovica), the latter of which served as a Roman capital during the Tetrarchy. Seventeen Roman Emperors were born in the area of modern-day Serbia, second only to contemporary Italy. The most famous of these was Constantine the Great, the first Christian Emperor, who issued an edict ordering religious tolerance throughout the Empire.
When the Roman Empire was divided in 395, most of Serbia remained under the Eastern Roman Empire, while its northwestern parts were included in the Western Roman Empire. By the early 6th century South Slavs, present throughout the Byzantine Empire in large numbers, merged with the native population (Dacians, Illyrians, Thracians) and assimilated them.
Chalcedon originated as a Megarian colony in 685 BCE. The colonists from Megara settled on a site that was viewed in antiquity as so obviously inferior to that visible on the opposite shore of the Bosphorus (with its small settlements of Lygos and Semistra on Seraglio Point), that the 6th-century BCE Persian general Megabazus allegedly remarked that Chalcedon's founders must have been blind. Indeed, Strabo and Pliny relate that the oracle of Apollo told the Athenians and Megarians who founded Byzantium in 657 BCE to build their city "opposite to the blind", and that they interpreted "the blind" to mean Chalcedon, the "City of the Blind".
The Western Roman Empire collapsed in the late 5th century. Romulus Augustulus is often considered to be the last emperor of the West after his forced abdication in 476, although Julius Nepos maintained a claim recognized by the Eastern Empire to the title until his death in 480. Following Nepos' death, the Eastern Emperor Zeno abolished the division of the position and proclaimed himself as the sole Emperor of a reunited Roman Empire. The Eastern imperial lineage continued to rule from Constantinople ("New Rome"); they continued to style themselves as Emperor of the Romans (later βασιλεύς Ῥωμαίων in Greek), but are often referred to in modern scholarship as Byzantine emperors. Constantine XI Palaiologos was the last Roman emperor in Constantinople, dying in the Fall of Constantinople to the Ottomans in 1453.
The first Christians in Rome were chiefly people who came from the East and spoke Greek. The founding of Constantinople naturally drew such people thither rather than to Rome, and then Christianity at Rome began to spread among the Roman population, so that at last the bulk of the Christian population in Rome spoke Latin. Hence the change in the language of the liturgy. ...The liturgy was said (in Latin) first in one church and then in more, until the Greek liturgy was driven out, and the clergy ceased to know Greek. About 415 or 420 we find a Pope saying he was unable to answer a letter from some Eastern bishops, because he had no one who could write Greek.
While there is evidence that the hill was inhabited as far back as the fourth millennium BC, it was Pericles (c. 495 – 429 BC) in the fifth century BC who coordinated the construction of the site's most important present remains including the Parthenon, the Propylaia, the Erechtheion and the Temple of Athena Nike. The Parthenon and the other buildings were damaged seriously during the 1687 siege by the Venetians during the Morean War when gunpowder being stored in the Parthenon was hit by a cannonball and exploded.
Several historians such as British historian Edward Gibbon and the Greek historian Dimitri Kitzikis have argued that after the fall of Constantinople, the Ottoman state took over the machinery of the Roman state, and that in essence the Ottoman Empire was a continuation of the Eastern Roman Empire under a thin Turkish Islamic guise. Kitzikis called the Ottoman state "a Greek-Turkish condominium". The American historian Speros Vryonis wrote that the Ottoman state was centered on "a Byzantine-Balkan base with a veneer of the Turkish language and the Islamic religion". Other historians have followed the lead of the Austrian historian Paul Wittek who emphasized the Islamic character of the Ottoman state, seeing the Ottoman state as a "Jihad state" dedicated to expanding the world of Islam. Another group of historians led by the Turkish historian M. Fuat Koprulu championed the ""gazi" thesis" that saw the Ottoman state as a continuation of the way of life of the nomadic Turkic tribes who had come from East Asia to Anatolia via Central Asia and the Middle East on a much larger scale, and argued that the most important cultural influences on the Ottoman state came from Persia. More recently, the American historian Heath Lowry called the Ottoman state a "predatory confederacy" led in equal parts by Turks and Greeks converted to Islam.
The site has been used for religious buildings since at least the 4th century, when an oratory stood on the site. A cathedral was built in the 9th century, but was badly damaged by Norman invasions and was replaced in the 10th century, from about 940, when bishop Milo built a Romanesque cathedral. This building was the location of the Council of Troyes that opened on 13 January 1128/29, at which the Order of the Knights Templar was confirmed and its rule established. The Romanesque cathedral was destroyed by fire in 1188.
The Metropolis of Pergamon () was an ecclesiastical territory (diocese) of the Ecumenical Patriarchate of Constantinople in western Asia Minor, modern Turkey. Christianity in the city of Pergamon (modern Bergama), was introduced already from 1st century AD, while the local Christian community comprised one of the seven Churches of Asia mentioned at the Book of Revelation, written by John of Patmos. The bishopric of Pergamon was twice promoted to a metropolis: during the 13th–14th centuries, as well as for a short period in 1922. Today the "Metropolis of Pergamon and Adramyttium" is the see of a titular metropolitan.
Syracuse was founded in 734 or 733 BC by Greek settlers from Corinth and Tenea, led by the "oecist" (colonizer) Archias. There are many attested variants of the name of the city including "Syrakousai", "Syrakosai" and "Syrakō". A possible origin of the city's name was given by Vibius Sequester citing first Stephanus Byzantius in that there was a Syracusian marsh () called "Syrako" and secondly Marcian's "Periegesis" wherein Archias gave the city the name of a nearby marsh; hence one gets "Syrako" (and thereby "Syrakousai" and other variants) for the name of Syracuse, a name also attested by Epicharmus. The settlement of Syracuse was a planned event, as a strong central leader, Arkhias the aristocrat, laid out how property would be divided up for the settlers, as well as plans for how the streets of the settlement should be arranged, and how wide they should be. The nucleus of the ancient city was the small island of Ortygia. The settlers found the land fertile and the native tribes to be reasonably well-disposed to their presence. The city grew and prospered, and for some time stood as the most powerful Greek city anywhere in the Mediterranean. Colonies were founded at Akrai (664 BC), Kasmenai (643 BC), Akrillai (7th century BC), Helorus (7th century BC) and Kamarina (598 BC).
Syracuse was founded by Greek colonists in 734 or 733 BC, part of Magna Graecia. According to the Catholic Encyclopedia: "Syracuse claims to be the second Church founded by St. Peter, after that of Antioch. It also claims that St. Paul preached there. ... In the times of St. Cyprian (the middle of the third century), Christianity certainly flourished at Syracuse, and the catacombs clearly show that this was the case in the second century." Across the Strait of Messina, Calabria on the mainland was also probably an early center of Christianity.
The site of Chalcedon is located on a small peninsula on the north coast of the Sea of Marmara, near the mouth of the Bosphorus. A stream, called the Chalcis or Chalcedon in antiquity and now known as the Kurbağalıdere (Turkish: "stream with frogs"), flows into Fenerbahçe bay. There Greek colonists from Megara in Attica founded the settlement of Chalcedon in 685 BC, some seventeen years before Byzantium.
The cross on top of the dome has been replaced by the conquering Ottomans with the symbol of Islam, the crescent moon.
After the Ottoman conquest of Constantinople in 1453 by Mehmed II, the church was enclosed inside the walls of the Topkapi palace. The Janissaries used the church as an arsenal until 1826. It was also used as a warehouse for military equipment and repository for trophies of arms and military regalia taken by the Turks. During the reign of Sultan Ahmet III (1703–1730) it was converted into the National Military Museum in 1726.
The Roman Empire, at its height (c. 117 CE), was the most extensive political and social structure in western civilization. By 285 CE the empire had grown too vast to be ruled from the central government at Rome and so was divided by Emperor Diocletian into a Western and an Eastern Empire. The Roman Empire began when Augustus Caesar became the first emperor of Rome (31 BCE) and ended, in the west, when the last Roman emperor, Romulus Augustulus, was deposed by the Germanic King Odoacer (476 CE). In the east, it continued as the Byzantine Empire until the death of Constantine XI and the fall of Constantinople to the Ottoman Turks in 1453 CE. The influence of the Roman Empire on western civilization was profound in its lasting contributions to virtually every aspect of western culture.
Nevertheless, trade thrived in Chalcedon; the town flourished and built many temples, including one to Apollo, which had an oracle. Chalcedonia, the territory dependent upon Chalcedon, stretched up the Anatolian shore of the Bosphorus at least as far as the temple of Zeus Urius, now the site of Yoros Castle, and may have included the north shore of the Bay of Astacus which extends towards Nicomedia. Important villages in Chalcedonia included Chrysopolis (the modern Üsküdar) and Panteicheion (Pendik). Strabo notes that "a little above the sea" in Chalcedonia lies "the fountain Azaritia, which contains small crocodiles".
During the Middle Ages, the island of Lesbos belonged to the Byzantine Empire. In the 1090s, the island was briefly occupied by the Turkish emir Tzachas. In the 12th century, the island became a frequent target for plundering raids by the Republic of Venice. After the Fourth Crusade (1202–1204) the island passed to the Latin Empire, but was reconquered by the Empire of Nicaea sometime after 1224. In 1354, it was granted as a fief to the Genoese Francesco I Gattilusio. The Gattilusi also ruled Old Phocaea on the Anatolian mainland and the town of Ainos in Thrace, but by the 1430s, with the precipitate decline of Byzantine power, they had also seized Thasos and Samothrace.
In the mid-5th century BC, when the Athenian Acropolis became the seat of the Delian League and Athens was the greatest cultural centre of its time, Pericles initiated an ambitious building project that lasted the entire second half of the century. The most important buildings visible on the Acropolis today — the Parthenon, the Propylaia, the Erechtheion and the temple of Athena Nike — were erected during this period. The Parthenon was built under the general supervision of the artist Phidias, who also had charge of the sculptural decoration. The architects Ictinos and Callicrates began their work in 447 BC, and the building was substantially completed by 432, but work on the decorations continued until at least 431.
The Pantheon (, ; , from Greek "Pantheion", "[temple] of all the gods") is a former Roman temple, now a church, in Rome, Italy, on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC – 14 AD). It was completed by the emperor Hadrian and probably dedicated about 126 AD. Its date of construction is uncertain, because Hadrian chose not to inscribe the new temple but rather to retain the inscription of Agrippa's older temple, which had burned down.
After Constantinople fell to the Ottoman Turks in 1453, the patriarchate came to care more directly for all the Orthodox living in the Ottoman Empire. Hovagim I was at the time the Metropolitan of Bursa. In 1461, Hovagim I was brought to Constantinople by Sultan Mehmed II and established as the Armenian Patriarch of Constantinople which the office was created solely with a political purpose. Sultan Mehmed II wanted Armenian-Greek separation. Constantinople become the real center of their ecclesiastical and national life. The Armenian patriarch and not the Catholicos of Etchmiadzin, was their most important national dignitary, as part of Mehmed's wish. In the Sultan's capital, lived the largest Armenian community in the world; and his civil-ecclesiastical authority made the Sultan practically the most powerful official among the Armenians at large. Before the Ottoman conquest in 1453 there were probably no Armenian churches in Constantinople. Since 1453, 55 new Armenian churches were built in Istanbul, some are from the 16th century.
The Imperial Library of Constantinople, in the capital city of the Byzantine Empire, was the last of the great libraries of the ancient world. Long after the destruction of the Great Library of Alexandria and the other ancient libraries, it preserved the knowledge of the ancient Greeks and Romans for almost 1,000 years. A series of unintentional fires over the years and wartime damage, including the raids of the Fourth Crusade in 1204, impacted the building itself and its contents. The library continued in substantial form until the city of Constantinople was conquered by the Ottoman Empire on 29 May 1453 when the library's considerable surviving contents were destroyed or lost. The library was founded by Constantius II (reigned 337–361 AD) who established a Scriptorium so that the surviving works of Greek literature could be copied for preservation. The Emperor Valens in 372 employed four Greek and three Latin calligraphers. The majority of Greek classics known today are known through Byzantine copies originating from the Imperial Library of Constantinople.
The Council of Chalcedon in 451 established Constantinople as a patriarchate with ecclesiastical jurisdiction over Asia Minor (the dioceses of Asiane and Pontus) and Thrace as well as over the barbaric territories, non-converted lands outside the defined area of the Western Patriarchate (Old Rome) and the other three patriarchates, Alexandria, Antioch and Jerusalem, gave it appellate jurisdiction extraterritorially over canon law decisions by the other patriarchs and granted it honours equal to those belonging to the first Christian see, Rome, in terms of primacy, Rome retaining however its seniority (canon xxviii). Leo I refused to accept this canon, basing himself on the fact that it was made in the absence of his legates. In the 6th century, the official title became that of "Archbishop of Constantinople, New Rome, and Ecumenical Patriarch."
The Moscow–Constantinople schism, also known as the Orthodox Church schism of 2018, is a schism which began on 15 October 2018 when the Russian Orthodox Church unilaterally severed full communion with the Ecumenical Patriarchate of Constantinople. This was done in response to a decision of the synod of the Ecumenical Patriarchate on 11 October 2018 which confirmed the intention of moving towards granting autocephaly (independence) to the Orthodox Church in Ukraine, to reestablish a stauropegion (church body ruled directly by the Ecumenical Patriarch) in Kiev, to revoke the legal binding of the letter of 1686 which led to the Russian Orthodox Church establishing jurisdiction over the Ukrainian Church, and to lift the excommunications which affected clergy and faithful of two unrecognized Ukrainian Orthodox churches. Those two churches, the Ukrainian Autocephalous Orthodox Church (UAOC) and the Ukrainian Orthodox Church – Kiev Patriarchate (UOC-KP), were competing with the Ukrainian Orthodox Church (Moscow Patriarchate) (UOC-MP) and were considered "schismatics" (illegally segregated groups) by the Patriarchate of Moscow.
