Byzantium or Byzantion was an ancient Greek city in classical antiquity that became known as Constantinople in late antiquity and Istanbul today. The Greek name Byzantion and its Latinization Byzantium continued to be used as a name of Constantinople sporadically and to varying degrees during the thousand-year existence of the Eastern Roman Empire, which also became known by the former name of the city as the Byzantine Empire. Byzantium was colonized by Greeks from Megara in the 7th century BC and remained primarily Greek-speaking until its conquest by the Ottoman Empire in AD 1453.
The fall of Constantinople, also known as the conquest of Constantinople, was the capture of the capital of the Byzantine Empire by the Ottoman Empire. The city was captured on 29 May 1453 as part of the culmination of a 55-day siege which had begun on 6 April.
A crescent shape is a symbol or emblem used to represent the lunar phase in the first quarter, or by extension a symbol representing the Moon itself.
The conjoined representation of a crescent and a star is used in various historical contexts, including as a prominent symbol of the Ottoman Empire, and in contemporary times, as a national symbol by some countries, and by some Muslims as a symbol of Islam, while other Muslims reject it as an Islamic symbol. It was developed in the Greek colony of Byzantium ca. 300 BC, though it became more widely used as the royal emblem of Pontic king Mithridates VI Eupator after he incorporated Byzantium into his kingdom for a short period. During the 5th century, it was present in coins minted by the Persian Sassanian Empire; the symbol was represented in the coins minted across the empire throughout the Middle East for more than 400 years from the 3rd century until the fall of the Sassanians after the Muslim conquest of Persia in the 7th century. The conquering Muslim rulers kept the symbol in their coinage during the early years of the caliphate, as the coins were exact replicas of the Sassanian coins.
A vexilloid is any flag-like (vexillary) object used by countries, organisations, or individuals as a form of representation other than flags. American vexillologist Whitney Smith coined the term vexilloid in 1958, defining it as
An object which functions as a flag but differs from it in some respect, usually appearance. Vexilloids are characteristic of traditional societies and often consist of a staff with an emblem, such as a carved animal, at the top.
The double-headed eagle is an iconographic symbol originating in the Bronze Age. The earliest predecessors of the symbol can be found in Mycenaean Greece and in the Ancient Near East, especially in Mesopotamian and Hittite iconography. Most modern uses of the emblem are directly or indirectly associated with its use by the Palaiologos dynasty of the Byzantine Empire, a use possibly derived from the Roman Imperial Aquila. High medieval iterations of the motif can be found in Islamic Spain, France, the Bulgarian Empire and the Serbian principality of Raška. From the 13th century onward it appeared within the Islamic world in the Seljuk Sultanate of Rum and the Mamluk Sultanate, and within the Christian world in Albania, the Holy Roman Empire, Russia, and Serbia. In a few places, among them the Holy Roman Empire and Russia, the motif was further augmented to create the less prominent triple-headed eagle.
Islam is an Abrahamic monotheistic religion teaching that there is only one God and that Muhammad is the last messenger of God. It is the world's second-largest religion, with over 2 billion followers (Muslims) comprising nearly a quarter of the world's population.
Loukas Notaras was a Byzantine Greek statesman who served as the last megas doux or grand Duke and the last mesazon of the Byzantine Empire, under emperors John VIII Palaiologos and Constantine XI Palaiologos.
Turkey has no official national emblem, but the crescent and star design from the national flag is in use on Turkish passports, Turkish identity cards and at the diplomatic missions of Turkey.
An Islamic flag is the flag representing an Islamic caliphate, religious order, state, civil society, military force or other entity associated with Islam. Islamic flags have a distinct history due to the Islamic prescription on aniconism, making particular colours, inscriptions or symbols such as crescent-and-star popular choices. Since the time of the Islamic prophet Muhammad, flags with certain colours were associated with Islam according to the traditions. Since then, historical caliphates, modern nation states, certain denominations as well as religious movements have adopted flags to symbolize their Islamic identity. Some secular states and ethnic or national movements also use symbols of Islamic origin as markers of heritage and identity.
The Byzantine Empire experienced cycles of growth and decay over the course of nearly a thousand years, including major losses during the early Muslim conquests of the 7th century. But the Empire's final decline started in the 11th century, and ended 400 years later in the Byzantine Empire's destruction in the 15th century.
The Byzantine–Ottoman wars were a series of decisive conflicts between the Byzantine Greeks and Ottoman Turks and their allies that led to the final destruction of the Byzantine Empire and the rise of the Ottoman Empire. The Byzantines, already having been in a weak state even before the partitioning of their Empire following the 4th Crusade, failed to recover fully under the rule of the Palaiologos dynasty. Thus, the Byzantines faced increasingly disastrous defeats at the hands of the Ottomans. Ultimately, they lost Constantinople in 1453, formally ending the conflicts.
The fall of Gallipoli was the siege and capture of the Gallipoli fortress and peninsula, by the Ottoman Turks, in March 1354. After suffering a half-century of defeats at the hands of the Ottomans, the Byzantine Empire had lost nearly all of its possessions in Anatolia, except Philadelphia. Access to the Aegean and Marmara seas meant that the Ottomans could now implement the conquest of the southern Balkans, and could advance further north into the Serbian Empire and Hungary.
The Byzantine Empire was ruled by the Palaiologos dynasty in the period between 1261 and 1453, from the restoration of Byzantine rule to Constantinople by the usurper Michael VIII Palaiologos following its recapture from the Latin Empire, founded after the Fourth Crusade (1204), up to the Fall of Constantinople to the Ottoman Empire. Together with the preceding Nicaean Empire and the contemporary Frankokratia, this period is known as the late Byzantine Empire.
The Palaiologan army refers to the military forces of the Byzantine Empire under the rule of the Palaiologos dynasty, from the late 13th century to its final collapse in the mid-15th century. The army was a direct continuation of the forces of the Empire of Nicaea, which itself was a fractured component of the formidable Komnenian army of the 12th century. Under the first Palaiologan emperor, Michael VIII, the army's role took an increasingly offensive role whilst the naval forces of the empire, weakened since the days of Andronikos I Komnenos, were boosted to include thousands of skilled sailors and some 80 ships. Due to the lack of land to support the army, the empire required the use of large numbers of mercenaries.
For most of its history, the Eastern Roman (Byzantine) Empire did not use heraldry in the Western European sense of permanent motifs transmitted through hereditary right. Various large aristocratic families employed certain symbols to identify themselves; the use of the cross, and of icons of Christ, the Theotokos and various saints is also attested on seals of officials, but these were often personal rather than family emblems. Likewise, various emblems were used in official occasions and for military purposes, such as banners or shields displaying various motifs such as the cross or the labarum. Despite the abundance of pre-heraldic symbols in Byzantine society from the 10th century, only through contact with the Crusaders in the 12th century, and particularly following the Fourth Crusade (1202–1204) and the establishment of Frankish principalities on Byzantine soil from 1204 onwards, did heraldic uses penetrate in Byzantium. A native Byzantine heraldry began to appear in the middle and lower rungs of aristocratic families in the 14th century, coinciding with the decline of imperial authority and with the fragmentation of political power under the late Palaiologan emperors. However, it never achieved the breadth of adoption, or the systematization, of its Western analogues.
The Shahada, also transliterated as Shahadah, is an Islamic oath and creed, and one of the Five Pillars of Islam and part of the Adhan. It reads: "I bear witness that there is no deity but God, and I bear witness that Muhammad is the Messenger of God."
A number of flags have been used to represent the cultural and geographical region of East Turkestan in Central Asia, particularly by states that broke away from China during rebellions in the late 19th and early 20th centuries. Nearly all the flags feature a star and crescent, a symbol of the region's Turkic and Islamic identity.
The Ottoman army was the military structure established by Mehmed II during his reorganization of the Ottoman state and its military. It resulted from a major reorganization of the standing army dating from the time of Sultan Orhan, which had centred on janissaries who were paid by salary rather than rewarded with booty or fiefs. The army built by Orhan had operated during the period of the rise of the Ottoman Empire.
After the conquest of Constantinople in 1453, the sultans of the Ottoman Empire laid claim to represent the legitimate Roman emperors. This claim was based on the right of conquest and mainly rested on possession of Constantinople, capital of the Byzantine Empire for over a millennium. The sultans could also claim to be rulers of the Romans since they ruled over the former Byzantine populace, which continued to identify as such. Various titles were used by the sultans to stress their claim, including kayser-i Rûm and basileus.
