Theodore I Laskaris or Lascaris was the first emperor of Nicaea—a successor state of the Byzantine Empire—from 1205 to his death. Although he was born to an obscure aristocratic family, his mother was related to the imperial Komnenos clan. He married Anna, a younger daughter of Emperor Alexios III Angelos in 1200. He received the title of despot before 1203, demonstrating his right to succeed his father-in-law on the throne.
Theodore II Doukas Laskaris or Ducas Lascaris was Emperor of Nicaea from 1254 to 1258. He was the only child of Emperor John III Doukas Vatatzes and Empress Irene Laskarina. His mother was the eldest daughter of Theodore I Laskaris who had established the Empire of Nicaea as a successor state to the Byzantine Empire in Asia Minor, after the crusaders captured the Byzantine capital, Constantinople, during the Fourth Crusade in 1204. Theodore received an excellent education from two renowned scholars, Nikephoros Blemmydes and George Akropolites. He made friends with young intellectuals, especially with a page of low birth, George Mouzalon. Theodore began to write treatises on theological, historical and philosophical themes in his youth.
John III Doukas Vatatzes, Latinized as Ducas Vatatzes, was Emperor of Nicaea from 1222 to 1254. He was succeeded by his son, known as Theodore II Laskaris.
Henry was the second Latin emperor of Constantinople. He was one of the leaders of the Fourth Crusade in which the Byzantine Empire was conquered and Latin Empire formed.
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.
Yolanda, often called Yolanda of Flanders, was Empress of the Latin Empire in Constantinople, first as the wife of Emperor Peter from 1216 to 1217 and thereafter in her own right until her death in 1219. Peter was captured and imprisoned before he could reach Constantinople, so Yolanda assumed the duties of governing the Empire. She was ruling Marchioness of Namur from 1212 until 1217.
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 Despotate of Epirus 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. The term "Despotate of Epirus" is, like "Byzantine Empire" itself, a modern historiographic convention and not a name in use at the time.
Theodore Komnenos Doukas was ruler of Epirus and Thessaly from 1215 to 1230 and of Thessalonica and most of Macedonia and western Thrace from 1224 to 1230. He was also the power behind the rule of his sons John and Demetrios over Thessalonica in 1237–1246.
Michael II Komnenos Doukas, Latinized as Comnenus Ducas, often called Michael Angelos in narrative sources, was from 1230 until his death in 1266/68 the ruler of the Despotate of Epirus, which included Epirus in northwestern Greece, the western part of Greek Macedonia and Thessaly, and western Greece as far south as Nafpaktos.
Alexios Komnenos Strategopoulos was a Byzantine aristocrat and general who rose to the rank of megas domestikos and Caesar. Distantly related to the Komnenian dynasty, 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 VIII 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.
Marie de Courtenay was an Empress of Nicaea. She was a daughter of Peter II of Courtenay and Yolanda of Flanders. She married Theodore I of Nicaea. Marie served as regent for her younger brother Baldwin II of Courtenay in 1228, and styled herself "Empress of Constantinople".
Lady of Neuville was the Empress consort of Robert of Courtenay, Latin Emperor of Constantinople. Her first name is unknown, though a number of genealogies have assigned her the name Eudoxie (Eudoxia). The name is possibly a confusion with Eudokia Laskarina, a Byzantine princess that was previously betrothed to Robert, whose name is Latinized to Eudoxia.
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 siege of Constantinople in 1260 was the failed attempt by the Nicene Empire, the major remnant of the fractured Byzantine Empire, to retake Constantinople from the Latin Empire and re-establish the City as the political, cultural and spiritual capital of a revived Byzantine Empire.
The Battle of Poimanenon or Poemanenum was fought in early 1224 between the forces of the two main successor states of the Byzantine Empire; the Latin Empire and the Byzantine Greek Empire of Nicaea. The opposing forces met at Poimanenon, south of Cyzicus in Mysia, near Lake Kuş.
Isaac Laskaris was a brother of Nicaean emperor Theodore I Laskaris, who along with his brother Alexios Laskaris fled to the Latin Empire and unsuccessfully tried to topple Theodore's successor, John III Doukas Vatatzes, in 1224.

Empire of Thessalonica is a historiographic term used by some modern scholars to refer to the short-lived Byzantine Greek state centred on the city of Thessalonica between 1224 and 1246 and ruled by the Komnenodoukas dynasty of Epirus. At the time of its establishment, the Empire of Thessalonica, under the capable Theodore Komnenos Doukas, rivaled the Empire of Nicaea and the Second Bulgarian Empire as the strongest state in the region, and aspired to capturing Constantinople, putting an end to the Latin Empire, and restoring the Byzantine Empire that had been extinguished in 1204.
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.
