Byzantine EmpireThe Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fall of the Western Roman Empire in the 5th century AD and continued to exist until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in the Mediterranean world.
TurkeyTurkey (Türkiye, ˈtyɾcije), officially the Republic of Türkiye (Türkiye Cumhuriyeti ˈtyɾcije dʒumˈhuːɾijeti), is a country located mainly on the Anatolian Peninsula in West Asia, with a small portion on the Balkan Peninsula in Southeast Europe. It borders the Black Sea to the north; Georgia to the northeast; Armenia, Azerbaijan, and Iran to the east; Iraq to the southeast; Syria and the Mediterranean Sea to the south; the Aegean Sea to the west; and Greece and Bulgaria to the northwest. Cyprus is off the south coast.
Latin EmpireThe Latin Empire, also referred to as the Latin Empire of Constantinople, was a feudal Crusader state founded by the leaders of the Fourth Crusade on lands captured from the Byzantine Empire. The Latin Empire was intended to replace the Byzantine Empire as the Western-recognized Roman Empire in the east, with a Catholic emperor enthroned in place of the Eastern Orthodox Roman emperors. The main objective of the Latin Empire was planned by Venice, which promoted the creation of this state for self-benefits.
Republic of VeniceThe Republic of Venice or Venetian Republic was a sovereign state and maritime republic in parts of present-day Italy (mainly northeastern Italy) that existed for 1100 years from AD 697 until AD 1797. Centered on the lagoon communities of the prosperous city of Venice, it incorporated numerous overseas possessions in modern Croatia, Slovenia, Montenegro, Greece, Albania and Cyprus. The republic grew into a trading power during the Middle Ages and strengthened this position during the Renaissance.
CrusadesThe Crusades were a series of religious wars initiated, supported, and sometimes directed by the Christian Latin Church in the medieval period. The best known of these military expeditions are those to the Holy Land in the period between 1095 and 1291 that were intended to conquer Jerusalem and its surrounding area from Muslim rule. Beginning with the First Crusade, which resulted in the conquest of Jerusalem in 1099, dozens of military campaigns were organised, providing a focal point of European history for centuries.
Republic of GenoaThe Republic of Genoa was a medieval and early modern maritime republic from the 11th century to 1797 in Liguria on the northwestern Italian coast. During the Late Middle Ages, it was a major commercial power in both the Mediterranean Sea and the Black Sea. Between the 16th and 17th centuries, it was one of the major financial centers in Europe. Throughout its history, the Genoese Republic established numerous colonies throughout the Mediterranean and the Black Sea, including Corsica from 1347 to 1768, Monaco, Southern Crimea from 1266 to 1475, and the islands of Lesbos and Chios from the 14th century to 1462 and 1566, respectively.
Empire of TrebizondThe Empire of Trebizond (Αυτοκρατορία της Τραπεζούντας), or Trapezuntine Empire, was a monarchy and one of three successor rump states of the Byzantine Empire, along with the Despotate of the Morea and the Principality of Theodoro, that flourished during the 13th through to the 15th century, consisting of the far northeastern corner of Anatolia (the Pontus) and the southern Crimea. The empire was formed in 1204 with the help of the Georgian queen Tamar after the Georgian expedition in Chaldia and Paphlagonia, commanded by Alexios Komnenos a few weeks before the sack of Constantinople.
NicaeaNicaea, Nicæa or Nicea (naɪ'si:ə , niːˈkae̯.a), also known as Nikaia (Νίκαια, Attic: nǐːkai̯a, Koine: ˈnikεa), was an ancient Greek city in the north-western Anatolian region of Bithynia that is primarily known as the site of the First and Second Councils of Nicaea (the first and seventh Ecumenical councils in the early history of the Christian Church), the Nicene Creed (which comes from the First Council), and as the capital city of the Empire of Nicaea following the Fourth Crusade in 1204, until the recapture of Constantinople by the Byzantines in 1261.
Despotate of EpirusThe Despotate of Epirus (Δεσποτᾶτον τῆς Ἠπείρου) was one of the Greek successor states of the Byzantine Empire established in the aftermath of the Fourth Crusade in 1204 by a branch of the Angelos dynasty. It claimed to be the legitimate successor of the Byzantine Empire, along with the Empire of Nicaea and the Empire of Trebizond, its rulers briefly proclaiming themselves as Emperors in 1227–1242 (during which it is most often called the Empire of Thessalonica).
Ecumenical Patriarch of ConstantinopleThe ecumenical patriarch (Οἰκουμενικός Πατριάρχης) is the archbishop of Constantinople (Istanbul) and New Rome, and primus inter pares (first among equals) among the heads of the several autocephalous churches which compose the Eastern Orthodox Church. The ecumenical patriarch is regarded as the representative and spiritual leader of the Eastern Orthodox Christians worldwide. The term ecumenical in the title is a historical reference to the Ecumene, a Greek designation for the civilised world, i.e.
