Land ingen Dúngaile

Land ingen Dúngaile (d. 890 AD) (sometimes spelled Lann or Flann; her patronymic sometimes Dúnlainge) was a Dál Birn princess of Osraige who was a noteworthy figure in Irish politics during a critical time in Viking-age Ireland.

She was the daughter of king Dúngal mac Fergaile (r. 802-842) of Osraige, a kingdom which witnessed a dramatic rise to power under the rule of her war-like brother Cerball mac Dúnlainge (r. 842-888), in which she had a hand. She was married three times to successive kings, and as such appears to have had a central role in cementing alliances between rival Irish kingdoms, but also in urging her husbands towards hostilities against Viking threats. As queen, she became the mother and grandmother to several noteworthy Irish kings, and is remembered as an exemplar for female nobility in Irish verse and genealogical texts. After the death of Cerball in 888, her brother Riagan mac Dúnlainge succeeded the Ossorian throne.

Princess Land had three famous husbands, who were kings in their own right; two of which reigned as high king over Ireland.

She first married king Gáethíne mac Cináeda of Loíchsi from a territory neighboring her home region of Osraige by whom she had a son, Cennétig mac Gáethíne, (d. 903), who also later reigned as king of Loíchsi.

She was married again to the famous High King of all Ireland, Máel Sechnaill mac Máele Ruanaid (r. 846 to 862) and gave birth to his formidable son Flann Sinna who was also High King from 879 to 916. She is thus also the grandmother of Flann's son, High King Donnchadh Donn mac Flainn. Her marriage to Máel Sechnaill is largely seen as part of a political alliance between the Dál Birn of Osraige and the Clann Cholmáin dynasty of Southern Uí Néill, as her brother Cerball mac Dúnlainge, king of Osraige also wedded Máel Sechnaill's daughter as an agreement in alienating Osraige away from the greater polity of Munster. The dual marriages however did not cease fighting between the two dynasties. Máel Sechnaill died in 862.
