The Palaiologan Dynasty, as the ruling dynasty of the Roman Empire, is one of the more powerful and connected political families in the world, with allies and resources across the European continent and considerable influence abroad. To their own people, the Palaiologans are seen as saviors of the Empire, even though the first few rulers of the dynasty were hard-fisted rulers who frequently fought amongst themselves in the pursuit of dramatically declining political power and prestige. There is truth to the statement, however, that the Palaiologan Dynasty helped save the Empire and allow it to recover its strength.
Palaiologos Main Branch (Roman Empire)
The Palaiologos-Halvar Branch was the ruling royal family from 1548 until the Bjelbo-Griffins revolt in 1649. The branch dynasty came to be when Emperor Thomas I of Constantinople married Queen Elsa I Halvar of Scandinavia. Their firstborn, a pair of twins, would form two new branches of rulers. Theodore, the first born, would become the Emperor of the Roman Empire, while Nikolaus, the second born, would become the King of Scandinavia as well as the founder of the branch dynasty.
Under the Palaiologos-Halvar dynasty, Scandinavia maintained close relations with the Roman Empire as well as entered the colonial race against other major European nations like Spain, France, and particularly Britannia, with which Scandinavia nearly came to war several times. Towards the mid-17th century, however, the Scandinavian military was drained from frequent wars in northern Germany and the Empire itself was likewise drained from colonial expansion and competition with the richer and more populated Britannia.
In 1649, John II Palaiologos-Halvar was killed by rebel forces loyal to Kristoffer Bjelbo-Griffins, who promptly took the throne shortly after. Despite Roman aid for several years prior, the Scandinavian Empire was unable to defeat the rebels, who took over the country. Roman forces were, however, able to evacuate the remaining members of John II's family and escort them to Constantinople, where their relatives granted them asylum. The members of the Palaiologos branch dynasty have lived in the Empire ever since, and have even occupied high levels of Roman governmental and military institutions.
Palaiologos-Aleramici Branch (Montferrat)
The Palaiologos-Aleramici Branch ruled Montferrat from 1306 with the death of John I Aleramici and the extinction of the Aleramici family. The new dynasty would rule until the mid-15th century, when their land was overrun by the competing powers of Savoy and Naples, despite considerable pressure being exerted by their relatives in Constantinople.
The exact fate of this branch dynasty is unknown, although many speculate that they continued to live as minor nobles in Savoy or Lombardy for generations afterwords. There is some thought that the Roman Empire encountered the dynasty during their campaign in Lombardy in the early 17th century and brought them back to Constantinople, although there is no conclusive evidence to prove such a theory.
