About Fallomon mac Con Congalt

Fallomon mac Con Congalt was a monarch.

Follaman mac Con Congalt (died 766), also written Fallomon mac Con Congelt, was King of Mide, a kingdom of the Uí Néill in central Ireland in modern County Westmeath and County Meath.

Background Follaman belonged to the Clann Cholmåin Bicc branch of the southern Uí Néill, a kin group which traced its descent from Colmån Bec, son of Diarmait mac Cerbaill and, rather less certainly, from Niall of the Nine Hostages. Clann Cholmåin Bicc's own lands lay around Lough Lene, in Mide, the west-central part of the southern Uí Néill kingdoms, from which the names Meath and Westmeath are derived. The remainder of the southern Uí Néill formed the kingdoms of Tethbae, in the north-west midlands, north and west of the River Inny and east of the River Shannon, and Brega in the east midlands, east of the upper part of the River Boyne and its tributary the River Blackwater. The leading branch of Clann Cholmåin Bicc was later known as the Coille Follamain, or Caille Follamain, after Follaman himself. Its name is preserved in that of Killallon, some miles north-west of Clonmellon.

Clann CholmĂĄin Bicc were perhaps in the shadow of the neighbouring Clann CholmĂĄin, in full Clann CholmĂĄin MĂĄir, the descendants of ColmĂĄn Bec's brother ColmĂĄn MĂĄr, whose lands lay to the south-west around the hill of Uisnech. Until the 8th century, both were in a secondary position, the leadership of the southern UĂ­ NĂ©ill being held by the SĂ­l nÁedo SlĂĄine of Brega, descended from Diarmait's son Áed SlĂĄine. During the period when the SĂ­l n'Áedo SlĂĄine were dominant in the midlands, only one descendant of ColmĂĄn Bec was prominent, his son Óengus mac ColmĂĄin who may, perhaps, have been King of Tara, or more probably was appointed as deputy in the midlands—he is called "king of the UĂ­ NĂ©ill" at his death—by northerner Suibne Menn.

In the 8th century, a prolonged internal struggle among the various branches of the Síl nÁedo Slåine led to their decline and the rise of Clann Cholmåin Måir and perhaps also Clann Cholmåin Bicc.

Life The last of Follaman's ancestors to be reported in the Irish annals is his great-grandfather FĂĄelchĂș, who died in the early 660s. The earliest record of Follaman is in 733. Early in that year open warfare broke out among the northern UĂ­ NĂ©ill, between Flaithbertach mac Loingsig of CenĂ©l Conaill, who was the reigning High King of Ireland, and Áed AllĂĄn of CenĂ©l nEĂłgain, who would eventually force Flaithbertach to abdicate and become a pilgrim or monk.

Later in the year, war is reported in the midlands. The Annals of Ulster record that Cathal—usually taken to be Cathal mac Finguine, King of Munster—was first of all defeated by Domnall Midi and Clann CholmĂĄin MĂĄir at Tailtiu, site of the main UĂ­ NĂ©ill Ăłenach, and then victorious against Follaman and Clann CholmĂĄin Bicc at the Hill of Ward, site of the Ăłenach of Tlachtga, second in importance only to that of Tailtiu. However, a recent reinterpretation of this record has been proposed. Rather than identifying Cathal with Cathal mac Finguine, Charles-Edwards suggests that this is Cathal mac Áeda of the SĂ­l n'Áedo SlĂĄine, King of Lagore.

Nothing further is recorded of Follaman until after the death of Domnall Midi in 763, at which time he appears as an ally of Domnall's kin and, in particular, Domnall's son Donnchad Midi. This alliance is presumed to have existed from the earliest part of Domnall's reign, if not before, which began when he defeated and killed Áed Allån in 743.

In 765 Follaman is recorded as aiding Donnchad against Murchad, another of Domnall Midi's sons. Murchad was killed at Carn Fiachach, near present-day Rathconrath, fighting against Follaman and Donnchad. Follaman was killed in 766, at which time he is called king of Mide. The Annals of Ulster call the killing "treacherous", while the Annals of Tigernach call it "deceitful". Since Donnchad was the main beneficiary—he became King of Mide after this—it has been suggested that the killing was on his orders.
