The Battle of Manzikert or Malazgirt was fought between the Byzantine Empire and the Seljuk Empire on 26 August 1071 near Manzikert, theme of Iberia. The decisive defeat of the Byzantine army and the capture of the Emperor Romanos IV Diogenes played an important role in undermining Byzantine authority in Anatolia and Armenia, and allowed for the gradual Turkification of Anatolia. Many Turks, travelling westward during the 11th century, saw the victory at Manzikert as an entrance to Asia Minor.
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/Roman Empire that fled after Constantinople was occupied by Western European and Venetian armed forces during the Fourth Crusade, a military 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 an army of Crusaders and the Republic of Venice after the capture of Constantinople and the surrounding environs.
The Treaty of Devol was an agreement made in 1108 between Bohemond I of Antioch and Byzantine Emperor Alexios I Komnenos, in the wake of the First Crusade. It is named after the Byzantine fortress of Devol. Although the treaty was not immediately enforced, it was intended to make the Principality of Antioch a vassal state of the Byzantine Empire.
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 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 Byzantine–Seljuk wars were a series of decisive battles that shifted the balance of power in Asia Minor and Syria from the Byzantine Empire to the Seljuks. Riding from the steppes of Central Asia, the Seljuks replicated tactics practiced by the Huns hundreds of years earlier against a similar Roman opponent but now combining it with new-found Islamic zeal. In many ways, the Seljuk resumed the conquests of the Muslims in the Byzantine–Arab Wars initiated by the Rashidun, Umayyad and Abbasid Caliphates in the Levant, North Africa and Asia Minor.
The Crusade of 1197, also known as the Crusade of Henry VI or the German Crusade, was a crusade launched by the Hohenstaufen emperor Henry VI in response to the aborted attempt of his father, Emperor Frederick I, during the Third Crusade in 1189–90. Thus the military campaign is also known as the "Emperor's Crusade".
The Byzantine Empire was ruled by emperors of the Angelos dynasty between 1185 and 1204 AD. The Angeloi rose to the throne following the deposition of Andronikos I Komnenos, the last male-line Komnenos to rise to the throne. The Angeloi were female-line descendants of the previous dynasty. While in power, the Angeloi were unable to stop the invasions of the Turks by the Sultanate of Rum, the uprising and resurrection of the Bulgarian Empire, and the loss of the Dalmatian coast and much of the Balkan areas won by Manuel I Komnenos to the Kingdom of Hungary.
The Battle of Philomelion of 1116 consisted of a series of clashes over a number of days between a Byzantine expeditionary army under Emperor Alexios I Komnenos and the forces of the Sultanate of Rûm under Sultan Malik Shah; it occurred in the course of the Byzantine–Seljuk wars. The Seljuk forces attacked the Byzantine army a number of times to no effect; having suffered losses to his army in the course of these attacks, Malik Shah sued for peace.
Between 780–1180, the Byzantine Empire and the Abbasid & Fatimid caliphates in the regions of Iraq, Palestine, Syria, Anatolia and Southern Italy fought a series of wars for supremacy in the Eastern Mediterranean. After a period of indecisive and slow border warfare, a string of almost unbroken Byzantine victories in the late 10th and early 11th centuries allowed three Byzantine Emperors, namely Nikephoros II Phokas, John I Tzimiskes and finally Basil II to recapture territory lost to the Muslim conquests in the 7th century Arab–Byzantine wars under the failing Heraclian Dynasty.
Joseph Tarchaneiotes was a Byzantine general primarily known for his lack of participation in the decisive Battle of Manzikert (1071).
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.
This history of the Byzantine Empire covers the history of the Eastern Roman Empire from late antiquity until the Fall of Constantinople in 1453 AD. Several events from the 4th to 6th centuries mark the transitional period during which the Roman Empire's east and west divided. In 285, the emperor Diocletian partitioned the Roman Empire's administration into eastern and western halves. Between 324 and 330, Constantine I transferred the main capital from Rome to Byzantium, later known as Constantinople and Nova Roma. Under Theodosius I, Christianity became the Empire's official state religion and others such as Roman polytheism were proscribed. And finally, under the reign of Heraclius, the Empire's military and administration were restructured and adopted Greek for official use instead of Latin. Thus, although it continued the Roman state and maintained Roman state traditions, modern historians distinguish Byzantium from ancient Rome insofar as it was oriented towards Greek rather than Latin culture, and characterised by Orthodox Christianity rather than Roman polytheism.
The sack of Constantinople occurred in April 1204 and marked the culmination of the Fourth Crusade. Crusader armies captured, looted, and destroyed parts of Constantinople, then the capital of the Byzantine Empire. After the capture of the city, the Latin Empire was established and Baldwin of Flanders was crowned Emperor Baldwin I of Constantinople in the Hagia Sophia.
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.
A Short History of Byzantium (1997) is a history of the Byzantine Empire by historian John Julius Norwich. It is a condensed version of his earlier three-volume work on the same subject, published from 1988 to 1995 in 1200 pages, which is approximately one page per year of historical time covered.
Baldwin of Antioch was a Frankish knight and general in service of the Byzantine Empire during the Byzantine–Seljuk Wars. He was the son of Princess Constance of Antioch and Raymond of Poitiers. His brother-in-law was Byzantine Emperor Manuel I Komnenos. An ally of the Emperor in his battles against the Seljuk Turks, Baldwin was one of his most trusted advisors and the only one of Manuel's senior commanders "of Western origin".
A reason for the longevity of the Byzantine Empire is how they managed their foreign relations. When excluding the Roman Empire of which the Byzantine Empire is a direct continuation of, it still stands as the longest living regime to have ruled in Europe. Armed combat was the primary method with the evolved traditions of the Roman Empire, however Byzantine diplomacy which eventuated with their many treaties was used extensively as well. A lot of what we know of the world during the Middle Ages comes from the records of Byzantine scholars, which were detailing the Empire's interactions.
