The Norse kingdoms of Britannia:
Beornice: the Kingdom of Beornice is one of the three main Norse realms in Englaland. It was estabilished in the end of the eighth century by the (in)famous Viking raider and warrior Ívarr Loðbrók hinn Beinlausi, also known as Ivar the Boneless. Commonly called "the Scourge of the Islands", Ivar is considered to be one of the most cruel and terrible Norse leaders to ever descend on Britannia; also, it is said that he was secretly part of the Røkkatrú cult. He first arrived in Britannia landing in what would would become Beornice, and utterly ravaged the land, killing or forcing to flee a vast part of the Saxon population. Then, the pale skinned Ivar continued his rampage across the northern part of Britannia, conquering Innse Gall and lastly the isle of Man. He was famous for his frequent use of the blood eagle as an execution method, performed by cutting the skin of the victim by the spine, breaking the ribs so they resembled blood-stained wings, and pulling the lungs out through the wounds in the victim's back before finally sparkling salt in the wounds. Today, Beornice is still rightfully feared as one of the most powerful Viking kingdoms in Britannia, and is home to some of the most fearsome Norse raiders of all the isles. The current king of Beornice is Guðrǫðr, residing in Dun Holm.
Jórvík: the Kingdom of Jórvík is the second of the Norse realms in Englaland. The founder of this kingdom was Hálfdan Ragnarrson, or Halfdan of York. Ivar's brother, he was the main leader of the so-called Great Heathen Army, a massive host of raiders and pillagers who ravaged Englaland in the first years of the ninth century. This immense army landed near the city of Eoforwic (later called Jórvík), barely leaving time for the bishops of the College to flee, and from there moved southwards, defeating many Celtic and Saxon kings, including Lucius Septimus Artorius, the then High King of the Brythons. While the Great Heathen Army conquered and pillaged many cities, including Londinium, Halfdan could not hold on to his conquest, except his great stronghold of Jórvík. He was said to be an exceptionally cruel man, surpassed only by his brother: he had many of his defeated enemies blood-eagled, and his now almost legendary rampage through Englaland left nothing but death and destruction in its path. Today, Jórvík is still a powerful fortress of the Norse, a hub of both traders and raiders. The current king of Jórvík is Sigfred.
Danelagh: the Kingdom of Danelagh is the southernmost of the Viking realms of Englaland, and also the most recently estabilished. The kingdom was born in 837, when Guthrum, a great Norse warlord, landed in Eastern Englaland and from there he began his advance eastwards, conquering much of Mercia. The Saxon kings, terrorized, feared that the nightmare of the Great Heathen Army was about to become reality once again: thus, they decided to elect Alfred as Bretwalda, believing that he would be able to stop Guthrum. And able he was: in the battle of Ethandun in 838 Alfred spectacularly defeated the Norse armies. However, Guthrum's power was far from being broken, and in the end, he reached a compromise with Alfred: he would keep the already conquered lands, while renouncing all claims on the other Saxon territories. Guthrum's later conversion to Pelagianism was a clever political move: realizing that his kingdom wouldn't last long with much of its population being still Saxon and Christian, and with Saxon Christian kings surrounding his borders, he decided to embrace and enforce Pelagianism as the state religion. Today, Danelagh is the only Norse kingdom which enjoys peaceful and friendly relations with its Saxon neighbors, and has become the most civilized and centralized of the Viking realms. The current king of Danelagh is Ivar, residing in Torksey.
Anglia: the Kingdom of Anglia is youngest of all the Viking realms in the islands, and also one of the smallest. It was founded in 842 by Sveinn Tjúguskegg, or Sweyn Forkbeard. King of Denmark, Sveinn was arguably the second greatest leader of Norse history, and the first one to take the title of Keisari (Emperor). Before arriving in Britain, Sveinn went on to increase his domains in Danmark and Norégr; then, at the head of a vast invasion army, he landed in Britain, conquering the great city of Ludenwic. Many Saxon and Norse lords bent their knee to him, and thus he created a great empire, spanning from Denmark to Scotland. He was a very cultured man, and liked to present himself as the rightful heir to Roman authority in Britain. However, he died only two years later, and his realm fell into a civil war as various relatives and sons of his fought for the throne. Eventually, his son Knútr the Great emerged victorious, and is considered to be the greatest leader of Norse history. He reunited his father's empire and expanded it vastly, leading expeditions all the way from Suomi to Vinland. Knútr as an Emperor ruled from his great capital, renamed Londinium in honor of the Roman Empire. The Emperor of Miklaríki died without heirs in 851, and his empire collapsed as every vassal king reclaimed his independence. The only trace that remains today is the small kingdom of Anglia, and the great city of Londinium. The current king of Anglia is Svend, residing in Londinium.
Orkneyjar: the Kingdom of Orkneyjar is the northernmost of all the Viking realms of Britannia, spanning from the far islands of Færeyjar to the upper regions of mainland Albion. It is one of the oldest Norse kingdoms in the islands, and tradition attributes its foundation to Rognvald Eysteinsson. Rognvald is thought to have been one of the most trusted companions of the semi-legendary warlord Ragnarr Loðbrók (father of Ívarr and Hálfdan), whom he accompanied in many expeditions, from the Volga to the Mediterranean. Eventually, Rognvald decided to create a realm of his own, and in the beginning of the second half of the seventh century in landed in the islands of Orkney, and there he set up his own kingdom. He often used the islands as a starting point for many great raids through Scotland and Northern Ireland, and he and his descendants attempted numerous times to subjugate the Pictish tribes, however unsuccessfully. Today, Orkneyjar is still a feared kingdom of raiders, pirates and plunderers, and the large sails of the Viking longships can be seen on the shores of the northen isles. The current king of Orkneyjar is Harald, residing in Rínansey.
Sudreyjar: the Kingdom of Sudreyjar is the realm founded by Ívarr Loðbrók during his rampage through northern Britannia. It is not clear how Ívarr died: most believe that he was killed during a raid in Éire and burned in a pyre, but another common version of the story holds that he died when his ship sunk in the Irish Sea during a terrible storm. This second version sparked a sort of legend or story that many Norse mothers tell their children to make them behave: Ívarr did not actually die, but was brought to Niflehimr by the stormwinds; in the days of Ragnarøkkr, he will return, at the head of an army of the dead, to pillage and plunder like none before. Of course, this is nothing but a superstitious legend. Ívarr had four children, between whom his dominions were split: to his secondborn was given the kingdom of Sudreyjar, which today is one of the greatest dens of pirates and raiders of all the isles. The current king of Sudreyjar is Guðröðr, residing in Fjarðargarðr.
Manx: the Kingdom of Manx is the third of the realms conquered by Ívarr Loðbrók, and later was inherited by his thirdborn. The island of Manx soon became the greatest Norse stronghold in the Irish Sea: from there, fleets of raiders, pirates and warriors left headed towards the farthest places of Britannia, from Fortriu to Cornovia. Given the small size of the island, fortifying it was relatively easy, and the island has gained the fame of being impregnable. The current king of Manx is Gunnar, residing in Sólabyr.
Ulaid: the League of Ulaid is the realm founded by the fourth son of Ívarr Loðbrók, Torfinn, and a most peculiar realm among those of the Norse. Finding himself without any realm to inherit, the fourth and last son of Ivar decided to create one of his own. Assembling a relatively small army, he landed in Northern Éire and, exploiting the weakness of the Irish High Kings he conquered a part of what would become Ulaid. Torfinn, however, was an intelligent and skilled diplomat and ruler. Realizing his scarce Viking host could not mantain his kingdom for much longer, he instead decided to offer the neighboring Irish rulers and chieftains a deal: they could bend the knee to him and enjoy absolute religious freedom, and a part of the incomes derived from trade. Many were hesitant, but in time almost all of Ulaid's rulers decided to submit to Torfinn's authority. The ruler of the newly born league of Ulaid turned his small number of longships into a trading fleet, and used the traditional Norse shipbuilding abilities to create more and more ships. Gold began to flow into Ulaid's coffers, and in time a League was formed, a sort of merchant republic in which the great and wealthy houses control the state, and elect a Speaker to act as a representative and head of state. Today, Ulaid is a melting pot of different cultures and religions, and one of the richest states in all of Britannia. The current Speaker of the League of Ulaid is Sigtryg, residing in Cúil Rathain.
