Kingdom of Alba
drawn on the map AD 900–1293
Alba is the Gaelic name for the kingdom that emerged in what is now Scotland, first appearing in the historical record in the early 10th century. Traditional accounts credit Cináed mac Ailpín (Kenneth MacAlpin, d. 858) with uniting Picts and Gaels c. 843 in a single kingdom — often dramatised (in later, unreliable tradition) as "MacAlpin's treason."

Names and the "union" question
Alba is the Gaelic name for the kingdom that emerged in what is now Scotland, first appearing in the historical record in the early 10th century. Traditional accounts credit Cináed mac Ailpín (Kenneth MacAlpin, d. 858) with uniting Picts and Gaels c. 843 in a single kingdom — often dramatised (in later, unreliable tradition) as "MacAlpin's treason." Modern scholarship heavily revises this narrative. As Alex Woolf (From Pictland to Alba) and Dauvit Broun argue, Kenneth is better understood as a king of the Picts (the Gaelic terminology being applied retrospectively); the Chronicles of the Kings of Alba actually make Kenneth's son Áed the last "king of the Picts" and his grandson Constantine II the first "king of Alba." The shift in nomenclature from "Pictland" to "Alba" is now generally placed in the reign of Constantine II (Causantín mac Áeda, r. 900–943), in whose lifetime the name Alba first appears; references making Kenneth the "first king" were probably inserted later to lend the new kingdom legitimacy. The transition, in short, was a gradual cultural and political Gaelicisation of the Pictish kingdom, not a single conquest.
Later kings and transition
Constantine II fought at Brunanburh (937) and abdicated in 943 to become a monk at St Andrews. Malcolm II (Máel Coluim mac Cinaeda, r. 1005–1034) consolidated the kingdom and, having no son, passed the crown to his grandson Duncan I, inaugurating the House of Dunkeld — the transition point toward the medieval Kingdom of Scotland.

- When is the Kingdom of Alba shown on the map?
- The border data draws the Kingdom of Alba AD 900–1293. The source samples borders at fixed dates, so a span can begin late or run on past the end.
