Answer the following question: Information:  - Theodore II Doukas Laskaris or Ducas Lascaris ("Theodros II Doukas Laskaris") (1221/1222  August 18, 1258) was Emperor of Nicaea from 1254 to 1258.  - Late Antiquity is a periodization used by historians to describe the time of transition from classical antiquity to the Middle Ages in mainland Europe, the Mediterranean world, and the Middle East. The development of the periodization has generally been accredited to historian Peter Brown, after the publication of his seminal work "The World of Late Antiquity" (1971). Precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD. Generally, it can be thought of as from the end of the Roman Empire's Crisis of the Third Century (c. 235  284) to, in the East, the early Islamic period (7th9th centuries), following the Muslim conquests in the mid7th century. In the West the end was earlier, with the start of the Early Medieval period typically placed in the 6th century, or earlier on the Western edges of the empire.  - A capital city (or simply capital) is the municipality exercising primary status in a country, state, province, or other region, usually as its seat of government. A capital is typically a city that physically encompasses the offices and meeting places of its respective government; the status as capital is often designated by its law or constitution. In some jurisdictions, including several countries, the different branches of government are located in different settlements. In some cases, a distinction is made between the official (constitutional) capital and the seat of government, which is in another place.  - Constantine the Great (27 February 272 AD  22 May 337 AD), also known as Constantine I or Saint Constantine (in the Orthodox Church as Saint Constantine the Great, Equal-to-the-Apostles), was a Roman Emperor from 306 to 337 AD. Constantine was the son of Flavius Valerius Constantius, a Roman Army officer, and his consort Helena. His father became "Caesar", the deputy emperor in the west, in 293 AD. Constantine was sent east, where he rose through the ranks to become a military tribune under the emperors Diocletian and Galerius. In 305, Constantius was raised to the rank of "Augustus", senior western emperor, and Constantine was recalled west to campaign under his father in Britannia (Britain). Acclaimed as emperor by the army at Eboracum (modern-day York) after his father's death in 306 AD, Constantine emerged victorious in a series of civil wars against the emperors Maxentius and Licinius to become sole ruler of both west and east by 324 AD.  - The Count of Flanders was the ruler or sub-ruler of the county of Flanders, beginning in the 9th century. The title was held for a time by the Holy Roman Emperor and the King of Spain. During the French Revolution in 1790, the county of Flanders was annexed to France and the peerage ceased to exist. In the 19th century, the title was appropriated by Belgium and granted twice to younger sons of the King of the Belgians. The most recent holder died in 1983.  - Constantinople  was the capital city of the Roman/Byzantine Empire (3301204 and 12611453), and also of the brief Latin (12041261), and the later Ottoman (14531923) empires. It was reinaugurated in 324 AD from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, and dedicated on 11 May 330 AD.  - An empire is defined as "an aggregate of nations or people ruled over by an emperor or other powerful sovereign or government, usually a territory of greater extent than a kingdom, as the former British Empire, French Empire, Brazilian Empire, Russian Empire, Ottoman Empire, Byzantine Empire or Roman Empire." An empire can be made solely of contiguous territories such as the Austro-Hungarian Empire, or of territories far remote from the homeland, such as a colonial empire.  - The Empire of Romania, more commonly known in historiography as the Latin Empire or Latin Empire of Constantinople, and known to the Byzantines as the Latin Occupation, was a feudal Crusader state founded by the leaders of the Fourth Crusade on lands captured from the Byzantine Empire. It was established after the capture of Constantinople in 1204 and lasted until 1261. The Latin Empire was intended to supplant the Byzantine Empire as the titular Roman Empire in the east, with a Western Roman Catholic emperor enthroned in place of the Eastern Orthodox Roman emperors. Baldwin IX, Count of Flanders, was crowned the first Latin emperor as Baldwin I on 16 May 1204. The Latin Empire failed to attain political or economic dominance over the other Latin powers that had been established in former Byzantine territories in the wake of the Fourth Crusade, especially Venice, and after a short initial period of military successes it went into a steady decline. Weakened by constant warfare with the Bulgarians and the unconquered sections of the empire, it eventually fell when Byzantines recaptured Constantinople under Emperor Michael VIII Palaiologos in 1261. The last Latin emperor, Baldwin II, went into exile, but the imperial title survived, with several pretenders to it, until the 14th century.  - The Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern-day Istanbul, which had been founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the "Roman Empire" (tr. ), or "Romania", and to themselves as "Romans".  - The Empire of Trebizond or the Trapezuntine Empire was a monarchy that flourished during the 13th through 15th centuries, consisting of the far northeastern corner of Anatolia and the southern Crimea. Originally formed during a revolt against the usurpation of the imperial throne by the grandsons of Emperor Andronikos I Komnenos, Trebizond (current Trabzon, Turkey, with which the name of the empire is a cognate) became a Byzantine Greek successor state established after the fall of the Eastern Roman Empire (Byzantine) in the Fourth Crusade, along with the Empire of Nicaea and the Despotate of Epirus. The Emperors of Trebizond pressed their claim on the Imperial throne for decades after the Nicaean reconquest of Constantinople in 1261.  - The Empire of Nicaea was the largest of the three Byzantine Greek successor 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. Founded by the Laskaris family, it lasted from 1204 to 1261, when the Nicaeans restored the Byzantine Empire in Constantinople.  - The Fall of Constantinople ('; Conquest of Istanbul) was the capture of the capital of the Byzantine Empire by an invading army of the Ottoman Empire on 29 May 1453. The Ottomans were commanded by the then 21-year-old Mehmed the Conqueror, the seventh sultan of the Ottoman Empire, who defeated an army commanded by Byzantine Emperor Constantine XI Palaiologos. The conquest of Constantinople followed a 53-day siege that had begun on 6 April 1453.  - Alexios Komnenos Strategopoulos ( Greek :    ) was a Byzantine general during the reign of Michael VIII Palaiologos , rising to the rank of megas domestikos and Caesar . Of noble descent , he appears in the sources already at an advanced age in the early 1250s , leading armies for the Empire of Nicaea against Epirus . After falling out of favour and being imprisoned by Theodore II Laskaris , Strategopoulos sided with the aristocrats around Michael Palaiologos , and supported him in his rise to the throne after Theodore II 's death in 1258 . He participated in the Pelagonia campaign in 1259 , going on to capture Epirus , but his successes were undone in the next year and he was captured by the Epirotes . Released after a few months , he led the unexpected reconquest of Constantinople from the Latin Empire in July 1261 , restoring the Byzantine Empire . He was captured again by the Epirotes in the next year and spent several years in captivity in Italy , before being released . He retired from public affairs and died in the early 1270s .  - Michael VIII Palaiologos or Palaeologus ("Mikhal VIII Palaiologos"; 1223  11 December 1282) reigned as Byzantine Emperor 12591282. Michael VIII was the founder of the Palaiologan dynasty that would rule the Byzantine Empire until the Fall of Constantinople in 1453. He recovered Constantinople from the Latin Empire in 1261 and transformed the Empire of Nicaea into a restored Byzantine Empire.  - Istanbul (or ), historically known as Constantinople and Byzantium, is the most populous city in Turkey and the country's economic, cultural, and historic center. Istanbul is a transcontinental city in Eurasia, straddling the Bosphorus strait (which separates Europe and Asia) between the Sea of Marmara and the Black Sea. Its commercial and historical center lies on the European side and about a third of its population lives on the Asian side. The city is the administrative center of the Istanbul Metropolitan Municipality (coterminous with Istanbul Province), both hosting a population of around 14.7 million residents. Istanbul is one of the world's most populous cities and ranks as the world's 7th-largest city proper and the largest European city.  - The Laskaris or Lascaris family was a Byzantine Greek noble family whose members formed the ruling dynasty of the Empire of Nicaea from 1204 to 1261 and remained among the senior nobility up to the dissolution of the Byzantine Empire, whereupon many emigrated to Italy and then to Smyrna (much later). According to George Pachymeres, they were also called Tzamantouros (T). The feminine form of the name is Laskarina ().  - Komnenos, Latinized Comnenus, plural Komnenoi or Comneni (, pronounced /komniní/), is the name of a noble family who ruled the Byzantine Empire from 1081 to 1185, and later, as the Grand Komnenoi (, "Megalokomnenoi") founded and ruled the Empire of Trebizond (12041461). Through intermarriages with other noble clans, notably the Doukai, Angeloi, and Palaiologoi, the Komnenos name appears among most of the major noble houses of the late Byzantine world.    Given the information, choose the subject and object entities that have the relation of 'occupation'.
