One legend states that the Irish were descended from one Míl Espáine, whose sons supposedly conquered Ireland around 1000 BC or later. The character is almost certainly a mere personification of a supposed migration by a group or groups from Iberia to Ireland. It is from this that the Irish were, as late as the 1800s, popularly known as "Milesian". Medieval Irish historians, over the course of several centuries, created the genealogical dogma that all Irish were descendants of Míl, ignoring the fact that their own works demonstrated inhabitants in Ireland prior to his supposed arrival.
This doctrine was adapted between the 10th and 12th centuries, as demonstrated in the works of Eochaidh Ua Floinn (936-1004); Flann Mainistrech (died 25 November 1056); Tanaide (died c. 1075) and Gilla Cómáin mac Gilla Samthainde (fl. 1072). Many of their compositions were incorporated into the compendium Lebor Gabála Érenn.
This tradition was enhanced and embedded in the tradition by successive historians such as Dubsúilech Ó Maolconaire (died 1270); Seán Mór Ó Dubhagáin (d.1372); Giolla Íosa Mór Mac Fir Bhisigh (fl. 1390–1418); Pilip Ballach Ó Duibhgeannáin (fl. 1579–1590) and Flann Mac Aodhagáin (alive 1640). The first Irish historian who questioned the reliability of such accounts was Dubhaltach Mac Fhirbhisigh (murdered 1671).
