Orkney (/ˈɔːrkni/), also known as the Orkney Islands, is an archipelago off the north coast of mainland Scotland. The plural name the Orkneys is also sometimes used, but locals now consider it outdated. Part of the Northern Isles along with Shetland, Orkney is 10 miles (16 km) north of Caithness and has about 70 islands, of which 20 are inhabited. The largest island, the Mainland, has an area of 523 square kilometres (202 sq mi), making it the sixth-largest Scottish island and the tenth-largest island in the British Isles. Orkney's largest settlement, and also its administrative centre, is Kirkwall.

Orkney is one of the 32 council areas of Scotland, as well as a constituency of the Scottish Parliament, a lieutenancy area, and an historic county. The local council is Orkney Islands Council.

Causantín mac Áeda (Modern Gaelic: Còiseam mac Aoidh, anglicised Constantine II; born no later than 879; died 952) was an early King of Scotland, known then by the Gaelic name Alba. The Kingdom of Alba, a name which first appears in Constantine's lifetime, was situated in what is now Northern Scotland.

The core of the kingdom was formed by the lands around the River Tay. Its southern limit was the River Forth, northwards it extended towards the Moray Firth and perhaps to Caithness, while its western limits are uncertain. Constantine's grandfather Kenneth I (Cináed mac Ailpín, died 858) was the first of the family recorded as a king, but as king of the Picts. This change of title, from king of the Picts to king of Alba, is part of a broader transformation of Pictland and the origins of the Kingdom of Alba are traced to Constantine's lifetime.

Norn is an extinct North Germanic language that was spoken in the Northern Isles (Orkney and Shetland) off the north coast of mainland Scotland and in Caithness in the far north of the Scottish mainland. After Orkney and Shetland were pledged to Scotland by Norway in 1468–69, it was gradually replaced by Scots. Norn is thought to have become extinct around 1850, after the death of Walter Sutherland, the language's last known speaker, though there are claims the language persisted as late as 1932.

Reay (/reɪ/, RAY; Scottish Gaelic: Ràth, [rˠaː]) is a village which has grown around Sandside Bay on the north coast of the Highland council area of Scotland. It is within the historic Parish of Reay and the historic county of Caithness.

The village is on the A836 road some 12 miles (19 km) west of the town of Thurso and 3 miles (4.8 km) west of Dounreay.

The Earldom of Orkney was a Norse territory ruled by the earls (or jarls) of Orkney from the ninth century until 1472. It was founded during the Viking Age by Viking raiders and settlers from Scandinavia (see Scandinavian Scotland). In the ninth and tenth centuries it covered the Northern Isles (Norðreyjar) of Orkney and Shetland, as well as Caithness and Sutherland on the mainland. It was a dependent territory of the Kingdom of Norway until 1472, when it was absorbed into the Kingdom of Scotland. Originally, the title of Jarl or Earl of Orkney was heritable.

Scandinavian Scotland was the period from the 8th to the 15th centuries during which Vikings and Norse settlers, mainly Norwegians and to a lesser extent other Scandinavians, and their descendants colonised parts of what is now the periphery of modern Scotland. Viking influence in the area commenced in the late 8th century, and hostility between the Scandinavian earls of Orkney and the emerging thalassocracy of the Kingdom of the Isles, the rulers of Ireland, Dál Riata and Alba, and intervention by the crown of Norway were recurring themes.

Scandinavian-held territories included the Northern Isles of Orkney and Shetland, the Hebrides, the islands of the Firth of Clyde and associated mainland territories including Caithness and Sutherland. The historical record from Scottish sources is weak, with the Irish annals and the later Norse sagas, of which the Orkneyinga saga is the principal source of information, sometimes contradictory although modern archaeology is beginning to provide a broader picture of life during this period.

Earl of Orkney, historically Jarl of Orkney, is a title of nobility encompassing the archipelagoes of Orkney and Shetland, which comprise the Northern Isles of Scotland. Originally founded by Norse invaders, the status of the rulers of the Northern Isles as Norwegian vassals was formalised in 1195. Although the Old Norse term jarl is etymologically related to earl, and the jarls were succeeded by earls in the late 15th century, a Norwegian jarl is not the same thing. In the Norse context the distinction between jarls and kings did not become significant until the late 11th century and the early jarls would therefore have had considerable independence of action until that time. The position of Jarl of Orkney was eventually the most senior rank in medieval Norway except for the king himself.

The jarls were periodically subject to the kings of Alba for those parts of their territory in what is now mainland Scotland (i.e. Caithness and Sutherland). In 1232, a Scottish dynasty descended from the mormaers of Angus replaced the previous family descended from the late 10th century jarl Torf-Einarr, although the isles remained formally subject to Norway. This family was in turn replaced by the descendants of the mormaers of Strathearn and later still by the Sinclair family, during whose time Orkney and Shetland became part of Scotland.
