Given the question: Information: - Great Britain, also known as Britain, is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago. - Scotland (Scots: ) is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is otherwise surrounded by the Atlantic Ocean, with the North Sea to the east and the North Channel and Irish Sea to the south-west. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles and the Hebrides. - Wessex ("kingdom of the West Saxons") was an Anglo-Saxon kingdom in the south of Great Britain, from 519 until England was unified by thelstan in the early 10th century. - thelred, Lord of the Mercians (or Ealdorman thelred of Mercia; died 911) became ruler of English Mercia shortly after the death of its last king, Ceolwulf II in 879. His rule was confined to the western half, as eastern Mercia was then part of the Viking-ruled Danelaw. thelred's ancestry is unknown. He was probably the leader of an unsuccessful Mercian invasion of Wales in 881, and soon afterwards he acknowledged the lordship of King Alfred the Great of Wessex. The alliance was cemented by the marriage of thelred to Alfred's daughter thelfld. - Old English or Anglo-Saxon is the earliest historical form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages. It was brought to Great Britain by Anglo-Saxon settlers probably in the mid 5th century, and the first Old English literary works date from the mid-7th century. After the Norman Conquest of 1066, English was replaced, for a time, as the language of the upper classes by Anglo-Norman, a relative of French, and Old English developed into the next historical form of English, known as Middle English. - At the Battle of Edington an army of the Anglo-Saxon kingdom of Wessex under Alfred the Great defeated the Great Heathen Army led by Guthrum on a date between 6 and 12 May AD878, soon resulting in the Treaty of Wedmore later the same year.The primary sources locate the battle at ""Ethandun"" or ""Ethandune"", and until a scholarly consensus identified its location with the present-day Edington in Wiltshire it was known as the Battle of "Ethandun", a name which continues to be used. - Edward the Elder ( Old English : Eadweard cyning ; c. 874 -- 877 -- 17 July 924 ) was an English king . He became king in 899 upon the death of his father , Alfred the Great . His court was at Winchester , previously the capital of Wessex . He captured the eastern Midlands and East Anglia from the Danes in 917 and became ruler of Mercia in 918 upon the death of thelfld , his sister . All but two of his charters give his title as '' Anglorum Saxonum rex '' or '' king of the Anglo - Saxons '' . He was the second king of the Anglo - Saxons as this title was created by Alfred . Edward 's coinage reads '' EADVVEARD REX . '' The chroniclers record that all England '' accepted Edward as lord '' in 920 . But the fact that York continued to produce its own coinage suggests that Edward 's authority was not accepted in Viking - ruled Northumbria . Edward 's eponym '' the Elder '' was first used in Wulfstan 's Life of St thelwold ( c. 996 ) to distinguish him from the later King Edward the Martyr . - Alfred the Great ("elf counsel" or "wise elf"; 849 26 October 899) was King of Wessex from 871 to 899. - Ealhswith or Ealswitha (died 5 December 902) was the wife of King Alfred the Great. Her father was a Mercian nobleman, thelred Mucil (or Mucel), Ealdorman of the Gaini, which is thought to be an old Mercian tribal group. Her mother was Eadburh, a member of the Mercian royal family, and according to the historian Cyril Hart she was a descendant of King Coenwulf of Mercia. - English is a West Germanic language that was first spoken in early medieval England and is now a global "lingua franca". Named after the Angles, one of the Germanic tribes that migrated to England, it ultimately derives its name from the Anglia (Angeln) peninsula in the Baltic Sea. It is most closely related to the Frisian languages, although its vocabulary has been significantly influenced by other Germanic languages in the early medieval period, and later by Romance languages, particularly French. English is either the official language or one of the official languages in almost 60 sovereign states. It is the most commonly spoken language in the United Kingdom, the United States, Canada, Australia, Ireland, and New Zealand, and is widely spoken in some areas of the Caribbean, Africa, and South Asia. It is the third most common native language in the world, after Mandarin and Spanish. It is the most widely learned second language and an official language of the United Nations, of the European Union, and of many other world and regional international organisations. It is the most widely spoken Germanic language, accounting for at least 70% of speakers of this Indo-European branch. - thelfld, Lady of the Mercians (died 12 June 918), ruled Mercia in the English Midlands from 911 until her death. She was the eldest daughter of Alfred the Great, king of the Anglo-Saxon kingdom of Wessex, and his wife Ealhswith. thelfld was born around 870 at the height of the Viking invasions of England. By 878 most of England was under Danish Viking rule, East Anglia and Northumbria having been conquered and Mercia partitioned between the English and the Vikings, but in that year Alfred won a crucial victory at the Battle of Edington. Soon afterwards the English-controlled western half of Mercia came under the rule of thelred, Lord of the Mercians, who accepted Alfred's overlordship. Alfred adopted the title King of the Anglo-Saxons, claiming to rule all English people not living in areas under Viking control. In the mid-880s, Alfred sealed the strategic alliance between the surviving English kingdoms by marrying thelfld to thelred. - Middle English (ME) is collectively the varieties of the English language spoken after the Norman Conquest (1066) until the late 15th century; scholarly opinion varies but the Oxford English Dictionary specifies the period of 1150 to 1500. This stage of the development of the English language roughly followed the High to the Late Middle Ages. - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south.
