Title: King Arthur (2004 film)
Content:  In the film, Arthur's father is a Roman general from the Imperial Roman army and his mother is a Celtic woman. In the historical notes of the legend, Arthur's father is Uther Pendragon, a famous Romano-British commander and one of Britain's earlier kings, and his mother is Igraine, a beautiful young woman who was once the wife of Gorlois, the Duke of Cornwall and one of Uther's loyal subjects. Arthur's knights are described differently in the film and the legend. In the film, Lancelot, Tristan, Bors and the other Knights of the Round Table are Sarmatian knights fighting for the glory of the Roman Empire. In historical notes, the Knights of the Round Table are Britons, knights of Romano-Celtic Britain fighting for the freedom of Britain against the Saxons. A round table is briefly present in the movie, where Arthur's knights regularly meet in equality, and which flummoxes the bishop Germanus when he cannot find a place at the table to distinguish his stature.
Title: King Arthur: The Role-Playing Wargame
Content:  The plot in King Arthur draws mainly on Arthurian legend, adding and intermixing foreign elements into it. The player takes the role of King Arthur himself, and commands his knights and armies to expand his kingdom. It is explained that Uther Pendragon, Arthur's father, failed to draw the sword Excalibur from the stone. Arthur, years later, pulls the sword from the stone, unleashing ancient forces upon Britannia.
Title: King Arthur's family
Content:   In Welsh Arthurian pre-Galfridian tradition, that is, from before the time of Geoffrey of Monmouth's 12th-century Historia Regum Britanniae (History of the Kings of Britain), Arthur was granted numerous relations and family members. Several early Welsh sources are usually taken as indicative of Uther Pendragon being known as Arthur's father before Geoffrey wrote, with Arthur also being granted a brother (Madog) and a nephew (Eliwlod) in these texts. Arthur also appears to have been assigned a sister in this material – Gwalchmei is named as his sister-son (nephew) in Culhwch and Olwen, his mother being one Gwyar. Culhwch and Olwen, the Vita Iltuti and the Brut Dingestow combine to suggest that Arthur's own mother was named Eigyr. The genealogies from the 13th-century Mostyn MS. 117 assert that Arthur is the

Regarding Arthur's own family, his wife is consistently stated to be Gwenhwyfar, usually the daughter of King Ogrfan Gawr (variation: 'Gogrfan Gawr', "[G]Ogrfan the Giant") and sister to Gwenhwyfach, although Culhwch and Bonedd yr Arwyr do indicate that Arthur also had some sort of relationship with Eleirch daughter of Iaen, which produced a son named Kyduan (Cydfan). Kyduan was not the only child of Arthur according to Welsh Arthurian tradition – he is also ascribed sons called Amr (Amhar), Gwydre, Llacheu and Duran. (See the Offspring section for 
Title: Historicity of King Arthur
Content:  Arthur was first styled as a king of the Britons in Geoffrey of Monmouth's pseudo-historical chronicle Historia Regum Britanniae (History of the Kings of Britain), which dates to c. 1136. Geoffrey also refers to Ambrosius Aurelianus (whom he calls Aurelius Ambrosius) as a king of Britain and an older brother of Uther Pendragon, father of Arthur, thus establishing a familial relationship between Aurelianus and Arthur. He identifies Aurelius Ambrosius as the son of Constantinus, a Breton ruler and brother of Aldroenus.
Title: King Arthur
Content:   Geoffrey of Monmouth's Historia Regum Britanniae, completed, contains the first narrative account of Arthur's life. This work is an imaginative and fanciful account of British kings from the legendary Trojan exile Brutus to the 7th-century Welsh king Cadwallader. Geoffrey places Arthur in the same post-Roman period as do Historia Brittonum and Annales Cambriae. He incorporates Arthur's father Uther Pendragon, his magician advisor Merlin, and the story of Arthur's conception, in which Uther, disguised as his enemy Gorlois by Merlin's magic, sleeps with Gorlois's wife Igerna (Igraine) at Tintagel, and she conceives Arthur. On Uther's death, the fifteen-year-old Arthur succeeds him as King of 
Title: King Arthur
Content:   King Arthur (Brenin Arthur, Arthur Gernow, Roue Arzhur) was a legendary British leader who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the late 5th and early 6th centuries. The details of Arthur's story are mainly composed of Welsh and English folklore and literary invention, and modern historians generally agree that he is unhistorical. The sparse historical background of Arthur is gleaned from various sources, including the Annales Cambriae, the Historia Brittonum, and the writings of Gildas. Arthur's name also occurs in early poetic sources such as Y Gododdin. Arthur is a central figure in

Various works furthermore mention or feature his nieces and occasionally also different nephews. There are furthermore various other more distant family members, such as the case of the historical Romano-British leader Ambrosius Aurelianus being turned into his uncle (Uther's brother) in Goeffrey's tradition deriving Arthur's lineage from the self-proclaimed Western Roman Emperor Constantine II of Britain, who in this version of the legend is presented as Arthur's grandfather. One important figure of no actual blood relation to Arthur is Ector, who in the stories of Arthur's incognito youth is often secretly his adoptive father following the death of Uther soon after his birth.
