York in the context of "Roman Britain"

Constantine I (27 February 272 – 22 May 337), also known as Constantine the Great, or known mononymously as Constantine, was Roman emperor from AD 306 to 337 and the first Roman emperor to convert to Christianity. He played a pivotal role in elevating the status of Christianity in Rome, the Edict of Milan decriminalising Christian practice and ceasing Christian persecution. This was a turning point in the Christianisation of the Roman Empire. He founded the city of Constantinople (now Istanbul) and made it the capital of the Empire, which it remained for over a millennium.

Born in Naissus, a city located in the province of Moesia Superior (now Niš, Serbia), Constantine was the son of Flavius Constantius, a Roman army officer from Moesia Superior, who would become one of the four emperors of the Tetrarchy. His mother, Helena, was a woman of low birth, probably from Bithynia. Later canonised as a saint, she is credited for the conversion of her son in some traditions, though others believe that Constantine converted her. He served with distinction under emperors Diocletian and Galerius. He began his career by campaigning in the eastern provinces against the Persians, before being recalled to the west in AD 305 to fight with his father in the province of Britannia. After his father's death in 306, Constantine was proclaimed as augustus (emperor) by his army at Eboracum (York, England). He eventually emerged victorious in Civil wars of the Tetrarchy against the emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324.

Flavius Valerius Constantius (c. 250 – 25 July 306), also called Constantius I, was a Roman emperor from 305 to 306. He was one of the four original members of the Tetrarchy established by Diocletian, first serving as caesar from 293 to 305 and then ruling as augustus until his death. Constantius was also father of Constantine the Great, the first Christian emperor of Rome. The nickname "Chlorus" (Ancient Greek: Χλωρός, lit. 'the Pale') was first popularized by Byzantine-era historians and not used during the emperor's lifetime.

As an Illyrian soldier of humble origin, Constantius had a distinguished military career and rose to the top ranks of the army. Around 289, he set aside Helena, Constantine's mother, to marry a daughter of Emperor Maximian, and in 293 was added to the imperial college by Maximian's colleague Diocletian. Assigned to rule Gaul, Constantius defeated the usurper Carausius there and his successor Allectus in Britain, and campaigned extensively along the Rhine frontier, defeating the Alamanni and Franks. When the Diocletianic Persecution was announced in 303, Constantius ordered the demolition of churches but did not actively hunt down Christians in his domain. Upon becoming senior emperor in May 305, Constantius launched a successful punitive campaign against the Picts beyond the Antonine Wall. He died suddenly at Eboracum (York) in July the following year.

Eboracum (Classical Latin: [ɛbɔˈraːkũː]) was a fort and later a city in the Roman province of Britannia. In its prime it was the largest town in northern Britannia and a provincial capital. The site remained occupied after the decline of the Western Roman Empire and ultimately developed into the present-day city of York, in North Yorkshire, England.

Two Roman emperors died in Eboracum: Septimius Severus in 211 AD, and Constantius Chlorus in 306 AD.

In archaeology, a biofact (or ecofact) is any organic material including flora or fauna material found at an archaeological site that has not been technologically altered by humans yet still has cultural relevance. Biofacts can include but are not limited to plants, seeds, pollen, animal bones, insects, fish bones and mollusks. The study of biofacts, alongside other archaeological remains such as artifacts are a key element to understanding how past societies interacted with their surrounding environment and with each other. Biofacts also play a role in helping archaeologists understand questions of subsistence and reveals information about the domestication of certain plant species and animals which demonstrates, for example, the transition from a hunter-gatherer society to a farming society.

Biofacts are differentiated from artifacts in that artifacts are typically considered anything purposefully manipulated or made by human art and workmanship, whereas ecofacts represent matter that has not been made or deliberately influenced by humans yet still has cultural relevance. Biofacts reveal how people respond to their surroundings.

Scandinavian York (Jórvík) or Viking York (Old Norse: Jórvík) is a term used by historians for what is now Yorkshire during the period of Scandinavian domination from late 9th century until it was annexed and integrated into England after the Norman Conquest; in particular, it is used to refer to York, the city controlled by these kings and earls. The Kingdom of Jórvík was closely associated with the longer-lived Kingdom of Dublin throughout this period.

Harold Godwinson (died 14 October 1066), also called Harold II, was the last crowned Anglo-Saxon king of England. Harold reigned from 6 January 1066 until his death at the Battle of Hastings on 14 October 1066, the decisive battle of the Norman Conquest. He was succeeded by William the Conqueror, the victor at Hastings.

Harold Godwinson was a member of the most powerful noble family in England, his father Godwin having been made earl of Wessex by King Cnut the Great. Harold, who served previously as earl of East Anglia, was appointed to his father's earldom on Godwin's death. After his brother-in-law, King Edward the Confessor, died childless on 5 January 1066, the Witenagemot convened and chose Harold to succeed him; he was probably the first English monarch to be crowned in Westminster Abbey. In late September, he defeated an invasion by rival claimant Harald Hardrada of Norway in the Battle of Stamford Bridge near York before marching his army back south to meet William at Hastings two weeks later, where he was killed in battle.

Eadric Streona (died 1017) was Ealdorman of Mercia from 1007 until he was killed by King Cnut. Eadric was given the epithet "Streona" (translated as "The Acquisitive”) in Hemming's Cartulary because he appropriated church land and funds for himself. Eadric became infamous in the Middle Ages because of his traitorous actions during the Danish re-conquest of England.

Eadric was one of at least eight children and had relatively humble beginnings: his father Ethelric attended the court of King Æthelred the Unready, but was of no great significance and is not known to have had any titles. Even before becoming an ealdorman, Eadric seems to have acted as Æthelred's enforcer; in 1006 he instigated the killing of the Ealdorman of York, Elfhelm. Eadric was married to Æthelred's daughter Eadgyth by 1009, thus becoming his son-in-law. Eadric was appointed Ealdorman of Mercia in 1007.

Greek Revival architecture is a style that began in the middle of the 18th century but which particularly flourished in the late 18th and early 19th centuries, predominantly in northern Europe, the United States, and Canada, and Greece following that nation's independence in 1821. It revived many aspects of the forms and styles of ancient Greek architecture, including the Greek temple. A product of Hellenism, Greek Revival architecture is looked upon as the last phase in the development of Neoclassical architecture, which was drawn from Roman architecture. The term was first used by Charles Robert Cockerell in a lecture he gave as an architecture professor at the Royal Academy of Arts in London in 1842.

With newfound access to Greece and Turkey, or initially to the books produced by the few who had visited the sites, archaeologist–architects of the period studied the Doric and Ionic orders. Despite its universality rooted in ancient Greece, the Greek Revival idiom was considered an expression of local nationalism and civic virtue in each country that adopted it, and freedom from the lax detail and frivolity that then characterized the architecture of France and Italy, two countries where the style never really took architecturally. Greek Revival architecture was embraced in Great Britain, Germany, and the United States, where the idiom was regarded as being free from ecclesiastical and aristocratic associations and was appealed to each country's emerging embrace of classical liberalism.
