Causantín mac Cináeda was a king of the Picts. He is often known as Constantine I in reference to his place in modern lists of Scottish monarchs, but contemporary sources described Causantín only as a Pictish king. A son of Cináed mac Ailpín, he succeeded his uncle Domnall mac Ailpín as Pictish king following the latter's death on 13 April 862. It is likely that the reign of Causantín witnessed increased activity by Vikings, based in Ireland, Northumbria and northern Britain. He died fighting one such invasion.
Causantín mac Áeda 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.
Kenneth MacAlpin or Kenneth I was King of Dál Riada (841–850), and King of the Picts (848–858), of likely Gaelic origin. According to the traditional account, he inherited the throne of Dál Riada from his father Alpín mac Echdach, founder of the Alpínid dynasty. Kenneth I conquered the kingdom of the Picts in 843–850 and began a campaign to seize all of Scotland and assimilate the Picts, for which he was posthumously nicknamed An Ferbasach. He fought the Britons of the Kingdom of Strathclyde and the invading Vikings from Scandinavia. Forteviot became the capital of his kingdom and Kenneth relocated relics, including the Stone of Scone from an abandoned abbey on Iona, to his new domain.
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.
Dál Riata or Dál Riada was a Gaelic kingdom that encompassed the western seaboard of Scotland and north-eastern Ireland, on each side of the North Channel. At its height in the 6th and 7th centuries, it covered what is now Argyll in Scotland and part of County Antrim in Northern Ireland. After a period of expansion, Dál Riata eventually became associated with the Gaelic Kingdom of Alba.

He is credited with having founded the church at Dunkeld which later received relics of St Columba from Iona.

The House of Alpin, also known as the Alpinid dynasty, Clann Chináeda, and Clann Chinaeda meic Ailpín, was the kin-group which ruled in Pictland, possibly Dál Riata, and then the kingdom of Alba from Constantine II in the 940s until the death of Malcolm II in 1034.
