Fortriu in the context of "Old Irish language"

The Picts were a group of peoples in what is now Scotland north of the Firth of Forth, in the Early Middle Ages. Where they lived and details of their culture can be gleaned from early medieval texts and Pictish stones. The name Picti appears in written records as an exonym from the late third century AD. They are assumed to have been descendants of the Caledonii and other northern Iron Age tribes. Their territory is referred to as "Pictland" by modern historians. Initially made up of several chiefdoms, it came to be dominated by the Pictish kingdom of Fortriu from the seventh century. During this Verturian hegemony, Picti was adopted as an endonym. This lasted around 160 years until the Pictish kingdom merged with that of Dál Riata to form the Kingdom of Alba, ruled by the House of Alpin. The concept of "Pictish kingship" continued for a few decades until it was abandoned during the reign of Caustantín mac Áeda.

Pictish society was typical of many early medieval societies in northern Europe and had parallels with neighbouring groups. Archaeology gives some impression of their culture. Medieval sources report the existence of a Pictish language, and evidence shows that it was an Insular Celtic language related to the Brittonic spoken by the Celtic Britons to the south. Pictish was gradually displaced by Middle Gaelic as part of the wider Gaelicisation from the late ninth century. Much of their history is known from outside sources, including Bede, hagiographies of saints such as that of Columba by Adomnán, and the Irish annals.

Columba (/kəˈlʌmbəˌ ˈkɒlʌmbə/) or Colmcille (7 December 521 – 9 June 597 AD) was an Irish abbot and missionary evangelist credited with spreading Christianity in what is today Scotland at the start of the Hiberno-Scottish mission. He founded the important abbey on Iona, which became a dominant religious and political institution in the region for centuries. He is the patron saint of Derry. He was highly regarded by both the Gaels of Dál Riata and the Picts, and is remembered today as a Catholic saint and one of the Twelve Apostles of Ireland.

Columba studied under some of Ireland's most prominent church figures and founded several monasteries in the country. Around 563 AD he and his twelve companions crossed to Dunaverty near Southend, Argyll, in Kintyre before settling in Iona in Scotland, then part of the Ulster kingdom of Dál Riata, where they founded a new abbey as a base for spreading Christianity among the pagan Northern Pictish kingdoms. He remained active in Irish politics, though he spent most of the remainder of his life in Scotland. Three surviving early-medieval Latin hymns are attributed to him.

The Kingdom of Alba (Latin: Scotia; Scottish Gaelic: Alba) was the Kingdom of Scotland between the deaths of Donald II in 900 and of Alexander III in 1286. The latter's death led indirectly to an invasion of Scotland by Edward I of England in 1296 and the First War of Scottish Independence.

Alba included Dalriada, but initially excluded large parts of the present-day Scottish Lowlands, which were then divided between Strathclyde and Northumbria as far north as the Firth of Forth. Fortriu, a Pictish kingdom in the north, was added to Alba in the tenth century.

Moray (Middle Irish: Muréb; Medieval Latin: Moravia; Old Norse: Mýræfi) was a province within the area of modern-day Scotland, that may at times up to the 12th century have operated as an independent kingdom or as a power base for competing claimants to the Kingdom of Alba. It covered a much larger territory than the modern council area of Moray, extending approximately from the River Spey in the east to the River Beauly in the north, and encompassing Badenoch, Lochaber and Lochalsh in the south and west.

Moray emerged in the 10th century as a successor to the dominant Pictish kingdom of Fortriu. The status of its rulers was ambiguous: being described in some sources as mormaers, in others as Kings of Moray, and in others as Kings of Alba. The ruling kin-group of Moray, sometimes called the House of Moray, attained the throne of Alba between 1040 and 1058 in the person of Mac Bethad mac Findláich (Shakespeare's Macbeth) and his stepson Lulach. After Lulach was killed and succeeded by Máel Coluim mac Donnchada of the House of Dunkeld, Lulach's son Máel Snechtai and grandson Óengus continued to rule Moray and challenge the kings to the south until Óengus' defeat and death at the Battle of Stracathro in 1130.
