Nicaea or Nicea was an ancient Greek city in northwestern Anatolia and is primarily known as the site of the First and Second Councils of Nicaea, the Nicene Creed, 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.
The 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 Empire of Nicaea or the Nicene Empire is the conventional historiographic name for the largest of the three Byzantine Greek rump states founded by the aristocracy of the Byzantine Empire that fled after Constantinople was occupied by Western European and Venetian forces during the Fourth Crusade, an event known as the Sack of Constantinople. Like other Byzantine rump states that formed after the 1204 fracturing of the empire, such as the Empire of Trebizond and the Empire of Thessalonica, it was a continuation of the eastern half of the Roman Empire that survived well into the medieval period. A fourth state, known in historiography as the Latin Empire, was established by the Crusaders and the Republic of Venice after the capture of Constantinople and the surrounding environs. It claimed to be the rightful continuation of the Roman Empire, despite having no meaningful connection to it.
The siege of Nicaea was the first major battle of the First Crusade, taking place from 14 May to 19 June 1097. The city was under the control the Seljuk Turks who opted to surrender to the Byzantines in fear of the crusaders breaking into the city. The siege was followed by the Battle of Dorylaeum and the Siege of Antioch, all taking place in modern Turkey.
The military history of Greece is the history of the wars and battles of the Greek people in Greece, the Balkans and the Greek colonies in the Mediterranean Sea and the Black Sea since classical antiquity.
The siege of Nicaea by the forces of Orhan I from 1328 to 1331, resulted in the conquest of a key Byzantine Greek city by the Ottoman Turks. It played an important role in the expansion of the Ottoman Empire.
The Byzantine–Ottoman wars were a series of decisive conflicts between the Ottoman Turks and Byzantines that led to the final destruction of the Byzantine Empire and the rise of the Ottoman Empire. In 1204 the Byzantine capital of Constantinople was sacked and occupied by the Fourth Crusaders, an important moment of the Christian East–West Schism. The Byzantine Empire, already weakened by misrule, was left divided and in chaos.
The siege of Nicaea of 1113 occurred in the course of the Byzantine-Seljuk wars.
Battle of Thessalonica, Siege of Thessalonica, or Sack of Thessalonica may refer to:
The siege of Constantinople (1235) was a joint Bulgarian-Nicaean siege on the capital of the Latin Empire. Latin emperor John of Brienne was besieged by the Nicaean emperor John III Doukas Vatatzes and Tsar Ivan Asen II of Bulgaria. The siege remained unsuccessful.
The Treaty of Nymphaeum was a trade and defense pact signed between the Empire of Nicaea and the Republic of Genoa in Nymphaion in March 1261. This treaty would have a major impact on both the restored Byzantine Empire and the Republic of Genoa that would later dictate their histories for several centuries to come.
The siege of Nicaea of 727 was an unsuccessful attempt by the Umayyad Caliphate to capture the Byzantine city of Nicaea, the capital of the Opsician Theme. Ever since its failure to capture the Byzantine Empire's capital, Constantinople, in 717–718, the Caliphate had launched a series of raids into Byzantine Asia Minor. In 727, the Arab army, led by one of the Caliph's sons, penetrated deep into Asia Minor, sacked two Byzantine fortresses and in late July arrived before Nicaea. Despite constant attacks for 40 days, the city held firm and the Arabs withdrew and returned to the Caliphate. The successful repulsion of the attack was a major boost for Byzantine emperor Leo III the Isaurian's recently initiated campaign to abolish the veneration of icons in the Empire; Leo claimed it as evidence of divine favour for his policy. The siege of Nicaea marks also the high point of the Umayyad raids, as new threats and defeats on their far-flung frontiers decreased Umayyad strength elsewhere, while Byzantine power strengthened afterwards.
Küçük Mustafa was an Ottoman prince who fought to gain control of the throne of the Ottoman Empire in 1422. It was used by the Ottoman chroniclers to distinguish him from his uncle Mustafa Çelebi, who also fought for the throne.
The siege of Sinope in 1214 was a successful siege and capture of Sinope by the Sultanate of Rum under their Sultan, Kaykaus I. Sinope was an important port city on the Black Sea coast of modern Turkey, at the time held by the Empire of Trebizond, one of the Byzantine Greek successor states formed after the Fourth Crusade. The siege is described in some detail by the near-contemporary Seljuq chronicler Ibn Bibi. The Trapezuntine emperor Alexios I led an army to break the siege, but he was defeated and captured, and the city surrendered on 1 November.
The Nicaean–Latin wars were a series of wars between the Latin Empire and the Empire of Nicaea, starting with the dissolution of the Byzantine Empire by the Fourth Crusade in 1204. The Latin Empire was aided by other Crusader states established on Byzantine territory after the Fourth Crusade, as well as the Republic of Venice, while the Empire of Nicaea was assisted occasionally by the Second Bulgarian Empire, and sought the aid of Venice's rival, the Republic of Genoa. The conflict also involved the Greek state of Epirus, which also claimed the Byzantine inheritance and opposed Nicaean hegemony. The Nicaean reconquest of Constantinople in 1261 AD and the restoration of the Byzantine Empire under the Palaiologos dynasty did not end the conflict, as the Byzantines launched on and off efforts to reconquer southern Greece and the Aegean islands until the 15th century, while the Latin powers, led by the Angevin Kingdom of Naples, tried to restore the Latin Empire and launched attacks on the Byzantine Empire.
