Calum is the Scottish Gaelic form of Columba — the Latin word for dove. Saint Columba (Colmcille in Irish, Calum Cille in Scottish Gaelic — 'dove of the church') founded the monastery of Iona in 563 AD, which became one of the most important centres of early Christian learning in Europe. His name was adopted by generations of Scots in his honour. Calum is the everyday name; Calum Cille (the full saint's name) is used in more formal or religious contexts.
Saint Columba transformed Christianity in Scotland and northern England. His monastery on Iona trained monks who spread across Scotland, Northumbria, and continental Europe. The name Calum carried his prestige throughout the medieval period. It remained one of the most common male names in the Highlands and Islands — particularly on Iona itself and in Argyll, where Columba's influence was strongest.
