Byzantine Empire under the Palaiologos dynasty
The Byzantine Empire was ruled by emperors of 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, 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.
From the start, the regime faced numerous problems. The Turks of Asia Minor had begun conducting raids and expanding into Byzantine territory in Asia Minor by 1263, just two years after the enthronement of the first Palaiologos emperor Michael VIII. Anatolia, which had formed the very heart of the shrinking empire, was systematically lost to numerous Turkic ghazis, whose raids evolved into conquering expeditions inspired by Islamic zeal, the prospect of economic gain, and the desire to seek refuge from the Mongols after the disastrous Battle of Köse Dağ in 1243. The Palaiologoi were engaged on several fronts, often continually, while the empire's supply of food and manpower dwindled. In this period, the Byzantine Empire found itself continually at war, both civil and interstate, with most interstate conflicts being with other Christian empires. Most commonly, these comprised the Second Bulgarian Empire, the Serbian Empire, the remnants of the Latin Empire and even the Knights Hospitaller.
The loss of land in the East to the Turks and in the West to the Bulgarians coincided with two disastrous civil wars, the Black Death, and the 1354 earthquake at Gallipoli which allowed the Turks to occupy the peninsula. By 1380, the Byzantine Empire consisted of the capital Constantinople and a few other isolated exclaves, which only nominally recognized the Emperor as their lord. Nonetheless, Byzantine diplomacy, political intrigue and the invasion of Anatolia by Timur allowed Byzantium to survive until 1453. The last remnants of the Byzantine Empire, the Despotate of the Morea and the Empire of Trebizond, fell shortly afterwards.
However, the Palaiologan period witnessed a renewed flourishing in art and the letters, in what has been called the Palaiologian Renaissance. The migration of Byzantine scholars to the West also helped to spark the Italian Renaissance.
Background
Following the Fourth Crusade, the Byzantine Empire had fractured into the Greek successor-states of Nicaea, Epirus, and Trebizond, with a multitude of Frankish and Latin possessions occupying the remainder, nominally subject to the Latin Emperors at Constantinople. In addition, the disintegration of the Byzantine Empire allowed the Bulgarians, the Serbs, and the various Turcoman emirates of Anatolia to make gains. Although Epirus was initially the strongest of the three Greek states, the Nicaeans succeeded in taking back the city of Constantinople from the Latin Empire.The Nicaean Empire was successful in holding its own against its Latin and Seljuk opponents. At the Battle of Meander Valley, a Turkic force was repelled and an earlier assault on Nicaea led to the death of the Seljuk Sultan. In the west, the Latins were unable to expand into Anatolia; consolidating Thrace against Bulgaria was a challenge that kept the Latins occupied for the duration of the Latin Empire.
In 1261, the Empire of Nicaea was ruled by John IV Laskaris, a boy of 10 years. However, John IV was overshadowed by his co-emperor, Michael VIII Palaiologos. Palaiologos was a leading noble of military standing and the main figure of the regency of John IV, who had used this role to propel himself to the throne, and set the stage for his becoming sole Emperor of the restored Byzantine Empire.
Michael VIII Palaiologos, 1261–1282
In 1261, while the bulk of the Latin Empire's military forces were absent from Constantinople, the Byzantine General Alexios Strategopoulos used the opportunity to seize the city with 600 troops. Thrace, Macedonia and Thessalonica had already been taken by Nicaea in 1246. Following the capture of Constantinople, Michael ordered the blinding of John IV in December 1261, so as to become sole emperor. As a result, Patriarch Arsenios excommunicated Michael, but he was deposed and replaced by Joseph I.Restoration of Constantinople
The Fourth Crusade and their successors, the Latin Empire, had done much to reduce Byzantium's finest city to an underpopulated wreck. Michael VIII began the task of restoring many monasteries, public buildings and defence works. The Hagia Sophia, looted in the Crusade of 1204, was refurbished to Greek Orthodox tradition. The Kontoskalion harbour and the walls of Constantinople were all strengthened against a possible new expedition by the Latin West. Many hospitals, hospices, markets, baths, streets and churches were built, some with private patronage. Even a new Mosque was built to compensate for the one burnt during the Fourth Crusade. These attempts were costly and crippling taxes were placed on the peasantry. Nonetheless, the city grew new cultural and diplomatic contacts, notably with the Mamelukes. Both had common enemies; Latin aggression, and later on, the Ottoman Turks.Foreign policy
The Sultanate of Rum was in chaos and decentralized ever since the Mongol invasions in ca. 1240. As a result, the greatest threat to Byzantium was not the Muslims but their Christian counterparts in the West — Michael VIII knew that the Venetians and the Franks would no doubt launch another attempt to establish Latin rule in Constantinople. The situation became worse when Charles I of Anjou conquered Sicily from the Hohenstaufens in 1266. In 1267, Pope Clement IV arranged a pact, whereby Charles would receive land in the East in return for assisting a new military expedition to Constantinople. A delay on Charles' end meant that Michael VIII was given enough time to negotiate a union between the Church of Rome and that of Constantinople in 1274, thus removing papal support for an invasion of Constantinople.Unfortunately for Michael VIII, the new union was seen as a fake by Clement's successor, Martin IV. The Greek Church was excommunicated, and Charles was given renewed papal support for the invasion of Constantinople. In order to counter this, Michael VIII subsidized Peter III of Aragon's attempts to seize Sicily from Charles. Michael's efforts paid off with the outbreak of the Sicilian Vespers, a revolt that overthrew the Angevin King of Sicily and installed Peter III of Aragon as King of Sicily in 1281.
For the remainder of his life, Michael campaigned to drive the Latins out of Greece and the Balkans, and secure his position versus the Bulgarians. He was largely successful, regaining several islands in the Aegean, and establishing a foothold in the Peloponnese, that would grow to become the Despotate of the Morea. The downside however was that Michael's efforts in the West absorbed most of the Empire's manpower and resources, and neglected the Asian provinces, where a new and fateful threat was rising: the beylik of Osman I, who by 1263 had captured Sogut. Nevertheless, the border was kept relatively secure, and no significant losses occurred in Asia Minor during Michael's reign.
Foreign policy
Michael VIII's foreign policy relied heavily on diplomacy; nevertheless, his construction projects and military campaigns against the remaining Latins were extensive as well as expensive; the Nicaean army was modeled around the Komnenian army, and while it was not as effective, it was just as burdensome on the treasury. The result was that heavy taxes were levied on the peasantry, something that the Ottomans would later use to their advantage, winning over these poverty-stricken peasants with promises of lower taxes.The Second Council of Lyons and the ostensible union of the two Churches did little to avert Catholic aggression, while at the same time the Orthodox population, led by large parts of the priesthood, denounced Michael VIII as a traitor. His death in 1282 came as a relief to many, and his body was denied an Orthodox funeral, as a result of his policies towards Rome.
Legacy
Michael VIII was a very energetic, ambitious and capable emperor who had enlarged and preserved the Empire and had once again made Byzantium a power to be reckoned with in the region. His army, however, was still small, and diplomacy was relied upon more than ever. An extortionate tax system supported his ambitious and successful foreign policies of expansion, as well as his numerous bribes and gifts to various potentates. He had put Byzantium on the road of recovery, but his achievements were still perilously fragile, as events would soon show.Andronikos II Palaiologos, 1282–1328
Andronikos II was the son of Michael VIII. He ascended the throne in 1282, at the age of 24.Foreign policy
Andronikos II was tied down with events in the West and the East. The Serbians under King Stefan Uroš II Milutin had begun invading the Balkans and took Skopje in 1282 and raids against Macedonia were launched throughout the 1290s. Byzantine counter-attacks failed to stop these, and as a result Andronikos was forced to resort to diplomacy, marrying his 5-year-old daughter to the Serbian King and ceding a number of forts from Ohrid to Stip to Strumica as a "dowry". Nonetheless, the Serbs continued their expansion.Unlike his father, Andronikos II recognized the gravity of the situation in Asia Minor, and tried to drive out the Turks, utilizing a variety of methods. His first action was to move his court to Asia Minor, where he could better oversee the construction of fortifications and raise troop morale. His General, Alexios Philanthropenos, was an able commander, campaigning with some success against the Turks in the Meander Valley. Unfortunately Byzantium was robbed of his services when he staged an unsuccessful coup, leading to his blinding. Next Andronikos sent his son, Michael IX, and the Heteriarch George Mouzalon to attack the Turks who were laying siege to Nicomedia, but they were beaten at the Battle of Bapheus in 1302.
Not giving up, Andronikos hired the 6,500 strong "Catalan Company" of Almogavars, led by Roger de Flor. Originating from Catalonia, these hardy mercenaries were used to skirmishing against the Moors in Spain and now, for an extraordinarily high price, they drove the Turks back in Asia Minor. Once again, these successes were nullified when their leader, Roger de Flor, was assassinated on his way to meet Andronikos; the Catalans then revolted against imperial authority, and began pillaging and raiding cities in Thrace, leaving Asia Minor open to Turkish incursions. After this, Andronikos turned to diplomacy, asking the Ilkhanids of Persia to send troops to attack the Turks, but negotiations for such an alliance failed.
