9th century in the context of "Al-Wathiq"

The Norse–Gaels (Old Irish: Gall-Goídil; Irish: Gall-Ghaeil; Scottish Gaelic: Gall-Gàidheal; Manx: Goal-Gael, 'foreigner-Gaels') were a people of mixed Gaelic and Norse ancestry and culture. They emerged in the Viking Age, when Vikings who settled in Ireland and in Scotland became Gaelicised and intermarried with Gaels. The Norse–Gaels dominated much of the Irish Sea and Scottish Sea regions from the 9th to 12th centuries. They founded the Kingdom of the Isles (which included the Hebrides and the Isle of Man), the Kingdom of Dublin, the Lordship of Galloway (which is named after them), and briefly ruled the Kingdom of York (939–944 AD). The most powerful Norse–Gaelic dynasty were the Uí Ímair or Ivar dynasty.

Over time, the Norse–Gaels became ever more Gaelicised and disappeared as a distinct group. However, they left a lasting influence, especially in the Isle of Man and Outer Hebrides, where most placenames are of Norse–Gaelic origin. Several Scottish clans have Norse–Gaelic roots, such as Clan MacDonald, Clan MacDougall and Clan MacLeod. The elite mercenary warriors known as the gallowglass (gallóglaigh) emerged from these Norse–Gaelic clans and became an important part of Irish warfare. The Viking longship also influenced the Gaelic birlinn and longa fada, which were used extensively until the 17th century. Norse–Gaelic surnames survive today and include MacIvor, MacAskill, and [Mac]Cotter.

The Lloyds Bank coprolite is a large coprolite, or fossilised specimen of human faeces, recovered by the York Archaeological Trust while excavating the settlement of Jórvík (present-day York) in northern England. The specimen was dated around the 9th century and offers insight into the dietary practices of the Anglo-Scandinavians during this period.

Hogwarts School of Witchcraft and Wizardry (/ˈhɒɡwɔːrts/) is a fictional boarding school of magic in the Harry Potter series by J. K. Rowling. It is the primary setting for the first six novels and films and also serves as a major setting in the Wizarding World media franchise.

In the novels, Hogwarts is described as a coeducational, secondary boarding school that enrolls children from ages eleven to eighteen. According to Rowling, any child in Britain who shows magical ability is invited to attend the school. The Wizarding World website states that Hogwarts was founded in the Highlands of Scotland sometime between the 9th and 10th century by Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin. Rowling has offered varying accounts of how many students are enrolled at Hogwarts at any given time.

The Icelandic horse (Icelandic: íslenski hesturinn [ˈistlɛnscɪ ˈhɛstʏrɪn]), or Icelandic, is a breed of horse developed in Iceland. Although the horses are smaller (at times pony-sized) than other breeds, most registries for the Icelandic refer to it as a horse. The breed is long-lived and hardy, owing to the ruggedness of its home country. In their native Iceland they have few afflictions or diseases, thus national laws are in place preventing foreign-born horses from being imported into the country, while exported animals are not permitted to return. In addition to the gaits of walk, trot, and canter/gallop, typical of other horse breeds, many Icelandic horses can also do the tölt (ambling gait) and the flying pace. The only breed of horse in Iceland, the Icelandic is also popular internationally, and sizable populations exist in Europe and North America. The breed is still used for traditional sheepherding work in its native country, as well as for leisure, showing, and racing.

Developed from ponies brought to Iceland by Norse settlers in the 9th and 10th centuries, the breed is mentioned in various documents from throughout Icelandic history; an early reference to a named-horse appears in the 12th century. Horses were venerated in Germanic religion, a custom brought to Iceland by the country's earliest settlers. Centuries of selective breeding have developed the Icelandic horse into its modern physical form, with natural selection having also played a role in overall hardiness and disease resistance; the harsh Icelandic climate likely eliminated many weaker horses early on due to exposure and malnourishment, with the strongest passing on their genes. In the 1780s, much of the breed was wiped out in the aftermath of a volcanic eruption at Laki. The first breed society for the Icelandic horse was created in Iceland in 1904, and the breed is represented by organizations in 22 different nations as of 2024, organised under a parent association, the International Federation of Icelandic Horse Associations.

Abahaṭ‌ṭha, Abahatta or Avahaṭṭha (Sanskrit apabhraṣṭa 'corrupted', related to apabhraṃśa) is a stage in the evolution of the Eastern group of the Indo-Aryan languages. This group consists of languages such as Assamese, Bengali, Bhojpuri, Magahi, Maithili, and Odia. Abahatta is considered to follow the Apabhraṃśa stage—i.e. those Apabhraṃśas derived from Magadhi Prakrit.

After different business and trading classes, including the Jains, rose in power and influence at the end of the ninth century CE, the widespread speaking of classical Sanskrit waned. Apabhransa and Abahatta thus became very popular, especially amongst common people, functioning as a lingua franca throughout the north of the Indian subcontinent.
